There's much to consider when sourcing I/O connectors for harsh environments

Despite all the warnings to avoid use of electrical devices in wet areas, it seems that designers are working at a fast pace to create devices that play well with water. Traditionally, most electronic boxes have been located in a sheltered, controlled environment. However, the proliferation of electronics into every industry has resulted in the need for designers to give serious consideration to enclosure and connector design elements that ensure a reliable product function for use in every environmental condition.

The most common harsh environment applications are found in the factory automation market, outdoor communications, portable or vehicle-mounted instrumentation or navigation systems, and security/surveillance equipment. The most common I/O connectors are D-subs, M12 and M8, RJ45 for Ethernet, USB 2.0, and LC fibre optic.

Sealing against liquid ingress

Just how ‘sealed' is a sealed connector? The industry has defined a range of Ingress Protection (IP) ratings, represented by a two-digit number. The first digit indicates the ability to shield against intrusion of foreign objects or particles, and the second digit indicates the strength of which the connection's ability to withstand various levels of pressure. Within the context of this article, the main ratings all start with a 6, which represents sealing against liquid:

* IP65, the ability to seal out low-pressure hose-directed liquids
* IP67, the ability to withstand light, temporary immersion in liquid (30 minutes@1 metre)
* IP68, the ability to withstand liquid immersion for a specified time and pressure
* IP69k, the ability to withstand very high-pressure liquid jets, directed at specified angles

Most I/O connectors are not sealed to IP65 specifications. Design enhancements are required to achieve the most common harsh environment rating, IP67. This usually means component and assembly changes to incorporate potting materials/solder, adhesives or ultrasonic welding, extra gaskets, and reliable means to compress these elastomeric seals. This is seldom achieved through the simple addition of room temperature curing sealants. IP67-sealed D-subs are readily available, and they offer the enhancements of a panel-to-connector seal and an elastomeric interfacial seal on one of the connectors.

IP68 tends to be an application-specific rating, so there is no universal set of tests. Thus, details are unique to the application and specified by the designer. This can range from a continuous low static pressure (e.g. a pot filled with dielectric oil), to long-term submersion of an instrument at the bottom of a tank. Hermetic-rated connectors are often specified for these conditions, with all the costs and complexities of glass seals and special metals for bonding.

IP69k is a special category that tends to be used in factory automation applications, and requires all components to withstand ‘pressure washer' type cleaning operations. Circular connectors, like the M12 and M8 families of I/O and sensor connections, may require such a rating. These types of connectors are typically used in the food and beverage packing industry.

Materials compatibility

A wet environment immediately brings concerns about corrosion of metal parts. The most common tin-plated steel I/O connectors, like D-subs, do not fare well in wet applications. As a result, designers should consider various plated copper alloy shells, nickel- or tin-plated zinc die-casting, or even stainless steel. For example, CONEC offers a wide variety of D-subs that are available in these more exotic materials

In addition to retaining integrity in water, components also must withstand various lubricants, fuels, test chemical agents, or gases. Thus, typical connector materials might not be suitable for this type of application. Design engineers need to calibrate their selection of component materials to account for all chemical aspects in the operating environment including where the device will be located geographically, since cold climates pose different environmental challenges than warm locations.

Ethernet RJ45 connectors and USB ports are available in sealed configurations and for harsh environments, including factory automation, outdoor instrumentation, navigation, or communications equipment. The connector bodies are available in a variety of plastics, or even die-cast zinc.

With connectors, there is no ‘one size fits all' recommendation for material compatibility. The designer must optimize the product selection based on all aspects of the application environment.

Temperature

Any time a device is used outside of a controlled environment, temperature extremes are sure to be a concern. Because of this, the normal temperature range of -25C to +85C is extended down to -40C or -55C, and up to 105C or 150C. Many connectors can withstand these extremes, but unique challenges should be considered. For example, thermal shock requirements can challenge even the most stringent MIL-spec standards, let alone commercial I/O connectors. Factoring in the need for sealing, plus the thermal shock parameters, choices quickly become limited. Most catalogue specifications do not detail thermal shock, so if this is important, designers must ensure the selected connector product testing matches these needs.

In the factory automation area, for example, using the circular family of connectors (e.g. M12 and M8) is optimal. Some are designed to withstand long-term exposure to 125C and 150C for 2,000 to 8,000 hours but most are rated from -30C to +85C, which is adequate for the typical sensor application. Again, selected connectors must be evaluated to the specific environmental needs of the application.

Don't Forget the Cables

Since I/O connections will involve a cable, the cable jackets need to be specified as well. Some performance parameters to consider include: UV and sunlight resistance, low temperature flex rating, chemical- or oil-resistance, weld slag tolerance, and high flex needs. It must also be able to withstand millions of cycles.

Cables may need a special hood/backshell to withstand the harsh environment. In the world of D-subs, there are liquid-sealed hoods available, which are also optimal for field installation. Overmoulded hoods are often a good choice, if implemented properly.

In the M12 and M8 families, overmoulded cable ends are extremely common. Overmoulding can improve durability, streamline size, and enhance the appearance of a cable connection. The increased durability is a result of the extra strain relief for wire terminations resulting from the overmould material bonding to the cable jacket. The overall assembly gives a high-reliability connector on each end with customer-specified cable properties in between.

Overmoulded connectors are available in right angle or straight, and shielded or unshielded options. They can also come with LEDs embedded in the overmould material for easy monitoring of signal integrity, or to indicate presence of power. These connectors are all IP rated as well.

RJ45, USB 2.0, and fibre optic LC connections, with their limited range of sizes and circular connector formats, are well suited to the use of field installed plug & boot kits. Factory-made cable sets are also available. Of course, shop pre-assembly is more typical in the case of LC connectors. The end result is an IP-rated connector system.

In summary, with proper design and careful component selection, the common connector formats for I/O connections can often be used in applications that require ruggedized components. With careful evaluation of the specifications, design engineers may be able to avoid expensive connector formats and utilize the cost savings of the various families of ruggedized commercial I/O connectors.

New product available from In2connect - IDC d-sub connector

2011-09-07T07:27:00.000-07:00

The new Conec IDC d-sub connector with stamped contacts provides a modular approach to electronic inter-connection. Outstanding features of the IDC connectors are high contact reliability, long life and low contact resistance.

These standard IDC D-sub connectors have stamped contacts. IDC technology is a solderless connection method which remains very popular in the mass production of electronic equipment.

Soldering can have several disadvantages ~ it can create thermal stress, and pretty obviously requires solder to be applied in what can be a costly reflow manufacturing process.

Insulation displacement contacts (IDCs) allow a ribbon cable to be forced onto sharp tines on the back of the contacts; this action pierces the insulation of all the wires simultaneously. This is a very quick means of assembly whether done by hand or automatically.The design these IDC dsub connectors offers a very reliable mass termination and cost effective approach to interconnecting PCBs, or wire-to-board applications.

Industrial In/Out Connectors

2011-03-18T08:32:00.000-07:00

Industrial USB Connectors from In2Connect UK Ltd

Industrial applications from the simplest hand held data logger to a fully blown industrial Ethernet system have carried the world’s best loved I/O connectors into a harsher and less tolerant environment. Industrial connectors face numerous environmental stresses. In order to support transportation, communications, networking, IT, medical systems, etc. they must match the level of product technology and the rapid development and growth of the sector and must combat temperature and humidity; exposure to liquids, oils and chemicals; shock or vibration and RF/EMI interference. Above all, whatever the specific application, they must provide absolute fail safe reliability.

In most industrial applications, waterproofing of components is arguably the first major add-on to the features required of an indoor interconnect and it has become very clear that many engineers and designers don’t want to reinvent interconnects for the sake of it, they want manufacturers to adapt products that they’ve already got built into BOMs.

As a prime example of this, whilst the D-sub I/O connector is a very mature product it remains extremely popular in instrumentation and industrial contexts and with the acceleration of rugged computers, hand held data loggers, etc. the connector manufacturer has seen an accelerating demand for more robust

D-sub designs both waterproof and filtered against RF or EMI. One only has to consider the extreme variety of applications demanding computerised control/communication systems to see what is driving this ~ everything from robotics systems in wet manufacturing; wash-down areas like milking parlours, food preparation plants, car washes; and networking technologies for automating discrete and process manufacturing plants.

As a consequence of this demand, EN 60529 an international classification system for the sealing effectiveness of enclosures for electrical equipment against the intrusion of foreign bodies and moisture was developed by the International Electrotechnical Commission. It isn’t specific to connectors, but they form an integral part of most entering or exiting most enclosures. This system utilizes the letters "IP" ("Ingress Protection") followed by two or three digits. The first digit indicates the degree that persons are protected against contact with moving parts and intrusion: 6 = No ingress of dust; and complete protection against contact.

The second digit indicates the degree of protection of the equipment inside the enclosure against the harmful entry of various forms of moisture (e.g. dripping, spraying, submersion, etc.): 7 = No ingress of water in harmful quantity when immersed in water under defined conditions of pressure and time (up to 1 m of submersion), i.e. temporary immersion. 8 = Suitable for continuous immersion in water under conditions which shall be specified by the manufacturer but is usually taken to cover depths say between 1 and 3 metres. It doesn’t cover the pressures associated with deep sea exploration, etc.

If one takes the ubiquitous D-sub connector, the aim has been to reduce the number of components that make up the connector, hence remove all possible leakage paths and manufacturers have generally produced an IP67 rated connector by adding a mounting plate with a silicone O-ring to create a watertight seal at the panel interface and back potting screw machined contacts to prevent water ingress through the connector body. These are now available in pretty much all of the standard d type configurations excepting crimp. Backpotting of the contacts has to be done once the contacts are embedded in the insulator, so the concept of a truly waterproof crimp d-sub would arguably cost too much to achieve?

Cost of course is amongst the leading drivers, thus the design concept for I/O connectors will always be limited by it ~ so in order to save space and reduce equipment size the industry needs to get more and more signals, such as common signals, microwave signals, optical signals, high voltage signals, power signals into a single connector whilst maintaining circuit or signal separation. This has been achieved with the IP67 mixed layout d-sub.

MIL-C circular connectors like the D38999 range provide waterproofing and environmental sealing; EMI/RFI shielding; shock and vibration proofing, but at a relatively high cost. So what does the electronic tap-ware industry do when not fitting baths into fighter aircraft? In2Connect was set this question when asked to develop low cost, functional waterproof connectors and the resulting Pintail circular range is an IP68 rated indoor/outdoor interconnect solution for industrial and electronics applications. These multi-pin, threaded coupling connectors will provide IP68 integrity when mated or when fitted with a waterproof end cap.

The connector bodies are moulded from glass filled nylon and are available in free plug, cable end receptacle and fixed jam nut receptacle formats, all with dust caps to suit. Contacts are interchangeable between plug and socket to allow design flexibility and polarisation. They were designed to be light weight, corrosion resistant and RoHS compliant with additional improved product features over competitive products; such as ~ planform contact identification by raised numbering for easy identification of circuits to save time and money when soldering or repairing incoming cables. Contacts are solder cup and are an integral part of the insulator, so less piece parts or crimp contacts to lose and no need for expensive crimp tools. To simplify the field assembly process, the dual O ring sealing means that the integral backshell can be easily removed in two sections to allow accurate soldering of the incoming cable. The threaded bodies provide a quick and easy connection to reduce installation and service time and have inbuilt key/keyway orientation with good cable waterproofing and retention by virtue of a rear compression nut. Not rocket science like the aluminium bodied MIL-Ccircular connectors, but then the proximity sensing electronic taps in our bathrooms aren’t for rocket fuel.

Ethernet has long been the standard communications protocol in the office, but the transition to Industrial Ethernet for shopfloor networks has meant reinforcement to the Ethernet and other similar connectors. Office or shopfloor are built on the same standards-based networking platform, the Ethernet local area network (LAN) standard IEEE 802.3. The key advantage of industrial Ethernet is that it allows manufacturers to deploy a single platform to enable interoperability in connecting workplace operations to corporate and office networks. However, there is a huge difference between installing Ethernet in a sheltered office environment and installing them on the manufacturing floor. If a connector or interconnect fails in a manufacturing system, the cost of parts replacement and repair will be insignificant compared to the indirect costs which could be associated with production downtime.

D-sub and circular multipin in/out connectors are relatively chunky with or without additional protection, but the transition of RJ45, USB, FireWire IEE 1394 and Optical Fibre to the industrial environment has required the application of the type of reinforcement associated with MIL-C circular connectors. For industrial real-time-Ethernet, the industry has gravitated toward an RJ45 connector type with a bayonet latching or screw threaded coupling mechanism according. This robust design with IP67 rating ensures reliable protection and easy connection under harsh environmental conditions.

It could be said that what goes around (the connector), comes around ~ and provides the called for reliability at the same time?

Non-Magnetic d-sub connectors from In2Connect

2011-03-09T02:21:00.000-08:00

Non-magnetic D-Sub I/O connectors suit medical applications ~ Mar 2, 2011

In2Connect has enhanced its Conec I/O connectors for use in areas with high magnetic fields by ensuring the connectors' own non-magnetic properties, replacing traditionally used steel shells and hardware with tin-plated brass and making the brackets of diecast zinc. Conec says its non-magnetic D-Sub I/O connector is ideal for medical imaging systems and other medical applications, as magnetic interference can severely compromise the observations as reported by doctors to patients.

"Typically, D-Sub I/O connectors used steel-stamped housing and steel hardware for the various configurations which can result in a magnetic attraction," explains Bob Hart technical manager at In2Connect UK Ltd. "By using copper alloy shells, tin-plated brass hardware components like screws or threaded rivets and diecast zinc brackets, this new connector is now completely non-magnetic. The connectors are utilized in a lot of medical equipment since it requires non- to low-magnetic components in order to maintain the integrity of the imaging."

In2Connect offers the Conec non-ferrous materials in all of the D-Sub connector families including high-density, standard and EMI filter connectors that are also widely used in medical imaging systems.

The non-magnetic D-subs are available to special order in standard densities of 9 through 50 positions, in solder cup and pc tail versions. High-density D-subs in the product line include sizes from 15 to 78 positions, also in solder cup and pc tail versions. Combination D-subs are available in 21 standard arrangements. EMI filter connectors are also available with this non-magnetic capability. Current ratings are from 5 to 40 amps, depending on the base connector chosen.

In2Connect UK launches IP68 rated Waterproof Circular Cable Connectors.

2010-11-17T12:48:00.000-08:00

The “Pintail” circular cable connector range from In2Connect provides low-cost, watertight, IP68 interconnects for industrial and electronics applications. Cable and panel connectors have threaded plastic shells with waterproof solder contacts.

The SP12 and SP21 connectors create an indoor/outdoor interconnect system which offers the form and function of MIL threaded connectors at the cost of a commercial (COTS) product. The SP13 (panel mounting hole size 13mm) and SP21 (panel mounting hole size 21mm) series of multi-pin, threaded coupling connectors are IP68 rated when mated or when fitted with a waterproof end cap and will work reliably indoors, outdoors and in harsh UV and fairly hostile wet environments. They are designed for safe control and LV power connections between equipment where IP68 is critical, e.g. in instrumentation, process control, industrial machinery, automotive, boating and other applications like outdoor lights, LED lights and LED display walls, outdoor security cameras, etc.
Developed by the European Committee for Electrotechnical Standardization (CENELEC), the IP Standards numerically rate an electrical product on the level of protection its enclosure provides. IP68 connectors must allow no ingress of dust with complete protection against electrical contact. They must also prevent ingress of water in harmful quantity when immersed long term under defined conditions of pressure and time (up to 1 m of submersion).
Using a combination of dual “O” ring sealing, high temperature PPS inserts, grommets and compression nuts; all insulator and contact areas in these connectors are fully sealed against environmental elements. The dual “O” rings mean that the integral backshell can be easily removed to allow accurate soldering of the incoming cable. Connector end caps are available to suit and IP68 integrity is achieved when male and female connectors are mated or when the IP68 end cap replaces a mating connector.
The screw machined brass, solder terminations on the SP21 range http://www.in2connect.uk.com/pintail.html are plated gold over nickel in cable free plug, in-line cable receptacle and jam nut panel mounting receptacle options.
Plug and receptacle housings are “keyed” to ensure correct polarisation and tactile feedback when mating. Unlike many competitors' products all the Pintail SP13/21 connectors have the option of male or female solder bucket contacts in any body shell; plus the ability to join cables with cable-end plug and in-line receptacle models.
Constructed of glass filled nylon, flammability rated V-0 shells with high temperature inserts these connectors have very stable dielectric and insulating properties plus they provide good mechanical properties at their design temperatures of -40 to 85 degrees C. They are RoHS compliant, CE approved, small, lightweight and extremely cost-effective when compared to their metal counterparts ~ without compromising the integrity of the interconnection.
Pintail connectors are designed for at least 500 mating cycles; backshell options can accommodate cable diameters from 3 to 12mm and they’re stocked in depth.

In the same water resisting family In2Connect also offer the chrome plated, brass bodied SF connector http://www.in2connect.uk.com/ip67_push_pull_metal.html. The SF12, IP67 has a self latching system which is renowned for its easy and quick mating/unmating features. It also provides security against vibration, shock or pull on the cable and facilitates operation in a very limited space. The push and pull system also allows the connector to be mated by simply pushing the plug axially into the socket. Once firmly latched, connection cannot be broken by pulling on the cable or any other release sleeve. When required, the connector is disengaged by a single axial pull on the outer release sleeve. It first disengages the latches and then withdraws the plug from the socket.

We offer a full range of IP67/69 rated environmentally sealed connectors http://www.in2connect.uk.com/waterproof_connectors.html designed to provide secure and safe connections in harsh or hostile conditions.

We've just given a totally new look to it, removing the rather "cartoon" like pictures and using real colour shots to enable searchers to know that they're looking at the correct product. Lots of clean white space to make product selection much easier on the eye.

Under the main headings of:

D-Sub I/O connectors
Circular connectors
Rectangular connectors
PCB and Backplane connectors
Waterproof connectors (which as you can see from the blog background, we're strong on!)
Cable and Harnessing

... you'll find the answer to many of your board-to-board, board-to-cable and cable-to-cable needs whilst Acrobat files of datasheets can be downloaded freely from the product page for each individual connector product line or from the Catalogues page.

Also new is a priced listing of our top moving items across all the categories with particular reference to our strong stocks of ITW McMurdo and Conec I/O connectors.

DIN 41612 connectors with tin/lead contact zones

2010-05-26T09:07:00.000-07:00

Do you still require non-RoHS DIN 41612 connectors for defence, avionics and other non-ROHS applications? In2Connect can still build these two part printed circuit board connectors which range up to 96 contacts in three rows on a 2.54mm grid.
Like their standard counterparts, these connectors conform to DIN 41612, EN 60603-2 and BS 9525 requirements. They are produced to special order in the Standard Forms B and C, plus B/2, C/2 and M but with the contact zone selectively gold plated and the contact tails (termination zone) tin/lead plated at the factory (Tin 63%/Lead 37%). MOQs as low as 250 pieces. For further details http://www.in2connect.uk.com/backplane-connector-din41612

Obsolete McMurdo d-sub connectors and hoods

2010-01-26T10:03:00.000-08:00

In2Connect UK Ltd is increasingly receiving requests for ITW McMurdo d-sub connectors and hoods which users believe to have been obsoleted. This seems to originate from explanations on the Farnell Electronics website which state "no longer manufactured" or "no longer stocked".
We're not complaining that customers are seeking other sources for components that Farnell no longer carry, because we're most certainly able to supply many of the dsub connectors, hoods, accessories, etc which have been the backbone of McMurdo's range over the years.
Please don't write-off a damn good manufacturer just because one distributor with a vast range of supply partners seemingly does so; there are other franchised suppliers of "McMurdo Connectors" ~ and we're proud to be the foremost.

ept offer a range of male IEC 60603-2 (DIN 41612) connectors for reflow soldering

2009-10-30T05:19:00.000-07:00

Until now, the most cost-effective means of applying a right angled male 41612 connector was to "press-fit" the connector to the PCB after all the other board components had been placed and reflow soldered. A logical addition to the standard press-fit male connectors, these new 'ept' "paste in hole" DIN 41612 THTR (Through-Hole Technology Reflow) types, can be fitted as with all other SMT reflow solder components before processing ~ completely eliminating the "press-fit" step and double handling of the PCB. The connector is manufactured with a high-temp plastic body moulding able to withstand a +260° C lead free soldering process to fulfil the requirements of J-STD-020D (Moisture/Reflow Sensitivity Classification for Non Hermetic Solid State Surface Mount Devices).

This all means less time, fewer production steps, and lower overall costs.

Samples of type C (male) 103-40064TH are available on request from us at In2Connect UK, other pin arrangements and models with boardlocks can be prepared.

DIN connectors are used in various applications with different termination methods. The DIN type C connectors are also available in press-fit and other solder technology.

We've just returned from the International Broadcast Convention (IBC) in Amsterdam. This is the leading international forum for the electronic media industry, but the experience leaves me wondering what future "real" as opposed to 'virtual' conventions and exhibitions have?
What a brilliant opportunity to network and 'learn' but seemingly less people are bothering. Is this a British phenomenon or are the rest of the world also finding that people are less inclined to spend the time and money? The internet's great but you really can't beat face to face contact.

According to a joint project between Napier and the University of Chichester engineers are making use of online tools to communicate and collaborate – particularly forums and LinkedIn – there appears to be a significant resistance to social media and viral marketing amongst a large section of the engineering audience. Could explain why no-ones reading this?
