M50-3112342

Headers, Receptacles, Female Sockets Overview

The M50-3112342 is a surface mount card edge connector manufactured by Harwin Inc. under the Archer M50 series. It features 46 positions arranged in two rows with a 1.27 mm (0.05 inch) pitch. The connector utilizes female contacts made of phosphor bronze, finished with gold plating for reliable signal transmission. Designed for board-to-board applications, it employs a locking mechanism to ensure secure mating. The insulator is constructed from black thermoplastic material rated UL94 V-0 for flame resistance. This component supports automated pick-and-place assembly processes.
