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.

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. These shapes work equally well with male and female connectors while the CMM320 and CMM340 use extended walls in the housings allowing them to be filled
and protect terminated contacts.

In2Connect recommend usage of Stycast 2651 MM with Catalyst 9 (8% – 10%) and can also offer harness assembly either pigtailed or complete.

NICOMATIC is certified ISO 9001:2000 and their quality management system is applicable to any type of development, manufacturing, assembly and delivery of systems, components and connections
