M300 Series Connectors

Harwin's M300 series is a 3.00 mm pitch high-reliability, high-performance connector range suited for aerospace, defense, industrial, and other harsh-environment applications. The connectors provide a choice of three, six, and ten contact board-to-board, cable-to-board, and cable-to-cable options for applications requiring up to 10 A in a confined space.

Featuring a rear wall to assist the back-potting for additional strain relief, the housings are designed with ‘scoop-proof’ mating requirements for added handling assistance. The housings come with jackscrew fixtures to assist with vibration and shock performance and are future-proofed with halogen-free, RoHS-compliant materials.
