Nicomatic EMM series
Rugged EMM Series connectors from Nicomatic meet or exceed MIL 83513-G & MIL-DTL 55302G connector standards, resist fluid immersion & salt spray, handle temperatures to +150C and are available in multiple different configurations.
EMM Series connectors from high performance interconnect systems manufacturer, Nicomatic meet or exceed the performance requirements of MIL 83513-G and MIL-DTL 55302G to reduce space and weight in the most extreme environments, including defence, space, motorsport, civil aviation, UAVs and robotics. The 1.27mm pitch EMM interconnects effect a 40% space reduction over their parent CMM Series and a 20% space saving when compared to standard Micro D connectors. A recent customer application was a sophisticated missile actuation system; others include the TUM Hyperloop pod motherboard.
On a 1.27mm pitch in 04 to 60 pin configurations, the EMM Series is highly modular, suited to both board to board (thanks to their secure wiping length) and board to wire (from gauge 24 to gauge 30) configurations, with male and female thru-hole and SMT straight and 90° variants as well as cabled versions available. 90° 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 purpose-built facility in France, EMM Series connectors have high-performance glass fibre composite moulding, copper alloy male pins and female pins featuring tulip technology – a clip with a 4-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 outstanding: rated voltage is 250V RMS at sea level, dielectric withstanding voltage 750V RMS. At high altitude, where the EMM Series is often specified, diaelectric withstanding voltage is 540V RMS at 30,000 feet and 465V 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.
