 Nicomatic CMM 220 Mixed Layout Micro Connectors, 2mm Pitch. Nicomatic are the inventor of the CMM micro-connector system developed for the defence, aerospace and transportation markets. |
|
|
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, 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.
The Nicomatic 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.
