M300 3.00mm Pitch Headers & Wire Housings

Harwin M300 3.00mm Pitch Headers and Wire Housings are a range of male and female, rectangular, fully shrouded, unsealed connectors with a temperature range of -65°C to +175°C. The M300 contains 3-contact Single Row and 6- or 10-contact Double Row connectors, capable of board-to-board, cable-to-board, and cable-to-cable configurations. Hard acid gold-plated (98% purity) for high performance and long service life, the cable contacts are barrel-crimp style and are replaceable in the housing. The cable housings have a low-profile potting wall to allow for back-potting that provides additional strain relief and some sealing.
