Nicomatic CMM Series 340 Mixed

nicomatic cmm 340 maleNICOMATIC CMM SERIES 340 MIXED HP/HF

Nicomatic innovation creates even more capability of design with the CMM340 series. By introducing the series 22 Power/ Coax contacts into the familiar 2mm pitch, 3 row CMM320 connector, almost every design choice is now possible


nicomatic cmm 340 femaleThis new series of micro-connectors offers the widest possible mixed layout choice present on the market today, up to 120 low frequency contacts, 64 high frequency or high power contacts, or virtually any combination of the three contacts. Coaxial high frequency contacts allow high speed signals up to 6GHz and high power (Series 22 up to 10 Amp and Series 30 up to 20 Amp). There are thousands of design capabilities providing a cost effective solution for your needs. The NICOMATIC CMM 340 Mixed Interconnect system is a 2mm pitch connector with 3 rows of LF contacts with HP or HF. High density, mixed layout, minimum of 6 LF contacts with up to 64 special High Frequency or High Power contacts. Proven high reliability under the most extreme environmental conditions.
The 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

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.
