M300 - 10A, 3mm pitch High-Reliability Connectors

M300 - 3mm pitch High-Reliability Connectors

Power Connectors with reliable performance in harsh applications

Compact Power in Harsh Environments

The M300 series is a 3.00mm pitch high-reliability, high performance connector range suited to aerospace, defense, industrial and other harsh environment applications.

It provides a choice of 3, 6 or 10 contact board-to-board, cable-to-board and cable-to-cable options for applications requiring up to 10A in a confined space. Featuring a rear wall to assist the backpotting for additional strain relief, the housings are designed with ‘scoop-proof’ mating requirements for added handling assistance.

Housings come with jackscrew fixtures to achieve vibration and shock performance, and are future-proofed with halogen-free, RoHS compliant materials.
