M50-3602542

The M50-3602542 is a 50-position (25+25), 2-row, 1.27mm pitch surface mount male pin header from Harwin's Archer M50 series. It features an unshrouded, push-pull fastening design with square pins made of copper alloy. The mating contact finish is gold flash (3.00µin) and the termination finish is tin, ensuring reliable connections in board-to-board or cable applications.

This connector is rated for 1A per contact with a maximum contact resistance of 20mΩ initial and 30mΩ after conditioning, per EIA-364-06C. The operating temperature range is -40°C to 105°C, and the insulation material is black thermoplastic with UL94 V-0 flammability rating. The insulation height is 1.00mm and the contact length is 3.00mm.

Designed for surface mount soldering, this header is suitable for automated assembly processes. The 1.27mm pitch and 1.27mm row spacing make it compatible with standard board-to-board stacking configurations. The part is packaged loose in box (standard package quantity not verified).

Typical applications include interconnecting PCBs in compact electronic devices where space is limited. The gold contact finish provides corrosion resistance and durability for repeated mating cycles.
