For years, standard D-sub-miniature connectors (MIL-DTL-24308) were the poster child in relation to overall ruggedness and reliability when it came to interconnect greatness. However, much of this has changed with the influx of today’s digital explosion.

These days designers are quickly realizing how big of an impact size and weight are playing within their design templates, despite its extensive track-record, this 0.100" pitch solution is no to fulfill today's military or advanced electronics system specifications for weight and space. In some instances this is also the case with Omnetics very own Micro D-sub connectors at 0.050" pitch per MIL-DTL-83513.

Enter MIL-DTL-32139…. A new connector specification designed to meet the requirements for today’s demanding military environment. These new Nanosized connectors, although small, must be even more rugged and reliable than connector options of years past, and Omnetics Nano-D connectors have proven to be a cut above the rest. With precision gold plated, flex pin contacts on a nominal pitch of 0.64mm (0.025"), this family of Nano-miniature connectors is ideal for mission critical applications ranging from Aerospace to down-hole drilling.

Omnetics Nano-D (Bi-Lobe®) is generally viewed militarily due in part to its overall ability to operate successfully under sinusoidal vibrations of 10 to 2000 Hz at up to 20 g’s, withstand 48-hours of salt spray without exposure of base metals affecting the connector’s performance, the ability to withstand 100 g’s of shock with no electrical discontinuity, not to mention the ability to operate at temperatures of -55 to +200 degrees Celsius.

A number of non-military markets, such as robotics, are quickly reaping the benefits in which this small, yet powerful, connector family can offer.  Regardless of the industry, circuit boards themselves are evolving, and they are doing so faster with the intention of performing more and more functions, but on half the size of their previous footprint. Meanwhile, the number of physical wires needed for data acquisition continues to rise, and as these data speeds increase, differential signal routing does as well, as do the number of drain wires necessary to facilitate the performance needed.

While this continues to be a design challenge for today's designer, this growth in wire count can easily be solved using Omnetics' Nano-D connectors wired in a format to account for these factors.  With many sizes and formats readily available in Omnetics COT’s and standards library, your design can be assembled quickly and pain free. Whether it be for initial testing or full out production, Omnetics Connector Corporation has you covered. Standard contact sizes mimic the likes of MIL-DTL-83513 and 24308 including: 9, 15, 21, 25, 31, 37, 51, 65 and 85 pins, all at .025" pitch. All standard wired offerings come pre-assembled with 18" of color coded 30 AWG Teflon® insulated wire. Longer lengths are also available upon request. Circuit board level options range from horizontal and vertical surface mount, to a number of thru-hole configurations. Panel mount housings are also available and have the ability to include an environmental seal and will inter-mate with all qualified MIL-DTL-32139 manufacturers.

Alongside the MIL-STD version, which requires a pair of 0-80# jackscrews to ensure a mated state, Omnetics has created the very first of its kind; a 100% tool-free, latching equivalent to the MIL-DTL-32139 Nano-D. Gone are the jackscrews, however, the overall ruggedness remains the same. Omnetics Latching Nano-D is the first latching Nano interconnect solution suitable for use in Military and Aerospace applications. The latches provide extra security, and are very simple to use requiring no screwdrivers to mate or un-mate, and best of all, the performance with the latches actually exceeds the Mil-Spec call out in regards to shock and vibration. One of Omnetics aerospace customers recently noted, “When you can ditch a screwdriver you can barely hold in the first place, and not lose any sleep over shock and vibe, you know you’ve found a good product.”

Another variation to the MIL-DTL-32139 standard which Omnetics design team has created is a Nano-D Hybrid offering. This connector type allows users the ability to add up to a (3) Amp “power” contact typically reserved for use in Micro-D (MIL-DTL-83513) related applications, and house them in conjunction with a (1) Amp “signal” Nano-D contact in a familiar layout one would typically find in a Nano-D form factor. This enables the user and NOT the connector company to determine the perfect combination of power and signal lines best suitable for your needs.

Nano-D connectors, although small, have proven their toughness and reliability time-in and time-out with circuitry used in robotics, weaponry, future soldier systems as well as Unmanned Vehicles technology. Other popular uses include: Portable surveillance and Field Communications electronics where size, weight, signal integrity and overall ruggedness are a must. These same connectors are also being used on a number of mission critical satellites that simply cannot afford reliability question marks. One common trend you’ll see; these applications all have extreme shock and vibration requirements to which Omnetics Nano-D passes with flying colors.

Omnetics has been a certified supplier to the military specification MIL-DTL- 32139 for Nano-D connectors since 2007, and is well experienced in assembly, performance and connector design. When customizing or varying from standard designs, Omnetics offers design support using SolidWorks® 3D modeling. This can include anything from adding back shells to cable shielding which assists in EMI Protection. Please consult the factory with any other questions.
