Applications

Applications

Nicomatic CMM micro-connectors are designed to meet or exceed the relevant electrical and environmental performances described in MIL-DTL-55302F and BS9525-F0033 standards. These connectors are much used in PCB applications where vibration could cause breakdown to safety systems, such as aircraft electronics.

Nicomatic has developed back potting services and shapes as a fast, flexible and reliable solution for harness protection in the CMM Connector Series. These backpotting solutions provide protection from moisture or debris to the contacts while offer strain relief to the wire and cable as an effective alternative to overmolding or backshells.

Nicomatic CMM Series 200 and Series 220 use backpotting shapes made from thermoplastic plastics (Polyethylene or Polypropylene) rated to 100ºC.
