The Nicomatic CMM 220 system is a low cost 2mm pitch connector with reliability under the most extreme environmental conditions. The Nicomatic CMM 220 range is similar to the popular McMurdo M200/M300 and Harwin Datamate 2mm series, but offers 'mixed layout' capabilities, 4 to 60 LF contacts, or up to 15 HF or HP contacts (series 30), hence providing the designer with a choice of High Frequency, High Power, Low Frequency and Fibre Optic in a common, space saving footprint. Termination styles are also available for through-hole, surface mount and press-fit. These connectors will intermate with similar ranges like those from Harwin and ATI.

An integral jacking mechanism provides security to the mated pair from the effects of vibration, whilst a high temperature insulator allows infrared or vapour phase soldering.

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.

In2Connect stock many popular examples of these great little connectors.
