Nicomatic CMM 220 mixed layout Micro connectors, 2mm pitch

 
 

The CMM 220 system is a low cost 2mm pitch connector with reliability under even the most extreme environmental conditions. Similar to the popular M200/M300 series it offers 'mixed layout' 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.
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.
This connector was designed for use in aerospace, instrumentation and control, military and transportation sectors with applications to date including IFES, HUD, mobile radios, power supplies and engine controls.
