ITW McMurdo 200/300 Micronector

M200M200/M300 High Density 2mm Connector.

This high density, low frequency, 2mm connector is a low cost product with proven reliability, enabling 'Board-to-Board', 'Board-to-Wire', or 'Wire-to-Wire' interconnections.


The 2mm pitch layout enables a 40% space saving over a conventional 2.54mm connector and is is ideal for applications where safety is key, the application is subject to high loads of vibration and shock or operates in harsh environments.

An optional spring latch is available to ensure security of interconnection between mated pairs.
