The NICOMATIC CMM 220 (LF) Interconnect system is a 2mm pitch connector with 2 rows of signal contacts, known for its reliability and security, adapted to the lowest possible environments. With a large range of frequency contacts from 4 to 60 ways, and backpotting option for flexibility.

nicomatic 220 signal maleThe Nicomatic CMM range was designed for use in aerospace, instrumentation and control, military and transportation sectors with applications to date including IFES, HUD, flight controls, FADEC units, radar, missiles, optoelectronic sighting systems, space satellites, mobile radios, power supplies, UAVs and engine controls.

Key Features

Features include:

  • PCB to PCB, board-to-wire and wire-to-wire connections
  • High density ­ saves up to 50% space and weight over conventional connectors or Sub-D
  • Mixed layout, LF, HF and HP in one footprint
  • 4 to 60 low frequency contacts, up to 2500 mating cycles
  • High reliability contact design for harsh environment usage
  • MIL-DTL-55302F and BS-9525-F0033 compliant
  • Resistant to solvents, radiation + oxygen free
  • RoHS and Reach compliant with tin whiskers free, gold plated contacts
  • 260ºC insulator allows infrared, wave or vapour phase
  • Secure latched or jackscrew locking for anti-vibration interconnection
  • Interchangeable and drop-in rpelacements for ITW McMurdo Micronector 220 and Harwin Datamate J-Tek Series. These ranges are comparable in fit, form and function.

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.
