Rugged board connectors in four-to-60-pin configurations for extreme conditions introduced by Nicomatic
BON-EN-CHABLAIS, France – Nicomatic in Bons-En-Chablais, France, is introducing the EMM series board connectors that meet the performance requirements of MIL 83513-G and MIL-DTL 55302G to reduce space and weight in extreme environments military and space applications.
The 1.27-millimeter pitch EMM interconnects effect a 40 percent space reduction over their parent CMM series and a 20 percent space saving when compared to standard Micro D connectors.
The connectors come in four-to-60 pin-configurations, and are modular, suited to board-to-board and board-to-wire configurations, with male and female thru-hole and SMT straight and 90-degree variants as well as cabled versions available.
90-degree EMM series interconnects feature ingenious integrated back protection, with the contacts protected by a proprietary design.
Hardware is interchangeable, with locking and guiding functions available on both male and female connectors to ensure no misalignment or mis-mating can occur.
Manufactured in Nicomatic's facility in France, EMM series rugged connectors have high-performance glass fibre composite molding, copper alloy male pins and female pins featuring tulip technology -- a clip with a four-finger spring contact made with the outer in copper alloy and beryllium copper inner.
Fixing hardware is passivated 300-series stainless steel. EMM interconnects can be mated and unmated up to 500 times. Electrical performance is rated voltage of 250 volts RMS at sea level, dielectric withstanding voltage 750 volts RMS.

At high altitude, where the EMM series is often specified, dielectric withstanding voltage is 540 volts RMS at 30,000 feet and 465 volts RMS at over 100,000 feet.
For extreme environments, the EMM series is qualified to withstand vibration, shock, extreme temperature cycling, fluid immersion, humidity, and salt spray corrosion.
For space applications, they are certified to meet the ASTM E595 (ECSS-Q-ST-70-02C) specification for thermal vacuum outgassing. For more information contact Nicomatic online at www.nicomatic.com.
