Harwin has introduced M300 series 10A high reliability connectors

Harwin M300 Series10A High Reliability Connectors

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.
