M50-3111142

Headers, Receptacles, Female Sockets Overview

The Harwin M50-3111142 is a surface-mount receptacle connector from the Archer M50 series. It features 22 positions arranged in two rows with a 1.27 mm (0.05 inch) pitch. The contacts are female sockets plated with gold, fabricated from phosphor bronze. Designed for board-to-board or wire-to-board applications, it utilizes a straight termination style suitable for SMD/SMT installation. The housing is constructed from black thermoplastic material, providing UL 94 V-0 flammability rating. Electrical specifications include a current rating of 1 A and an insulation resistance of 1 GOhm. Operating temperature ranges from -40°C to +105°C.
