DESCRIPTION OF CONNECTOR AND INTENDED APPLICATION The M300 connector series is a range of 3mm pitch male and female rectangular, fully shrouded, unsealed connectors. The range covers 3-contact Single Row and 6-contact Double Row connectors, capable of board-to-board, cable-to-board and cable-to-cable configurations. All female connectors are scoop-proof, and available in Cable and Vertical PC Tail versions. Male connectors use Ø1mm contacts to achieve up to 10A per contacts, and are available in Cable and Vertical PC Tail versions. The connectors are gold plated for high performance and long service life, with a hard acid gold at 98% purity. 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 - this provides additional strain relief and some sealing. The M300 Connectors are designed as a 5-10A Power connector for High-Reliability applications. Connector housings are fitted with jackscrews for secure interconnection. 2. RATINGS 2.1.

This may apply in cases where engagement and separation forces are so high as to prevent satisfactory hand engagement, or where access to connector is restricted. Jackscrews also provide a locking feature, preventing the connector from disengaging under adverse conditions. In order to obtain maximum effectiveness from the jackscrew system, the following rules for their use should be observed. 1. On engaging the two halves of the connector after ensuring correct polarity, lightly push home the floating half until the jackscrews touch. Then, maintaining the pressure, turn one of the floating jackscrews clockwise, until it engages with the fixed screw. Repeat with the other screw. 2. Then screw in each jackscrew, ensuring even loading by applying a maximum of one turn to each screw in sequence until the connector is bottomed. This will be evident by a sudden increase in the torque required on the screw. This torque should not exceed 23cmN. NB: Care to be taken when aligning male and female threads to avoid cross-threading and possible failure of parts. 3. On disengaging the two halves of the connector turn each of the floating jackscrews anticlockwise. Again ensure even loading by turning each screw in sequence for a maximum of one turn until the jackscrew disengage. The connector can then be easily pulled apart. -7-
