M50-3203845

Headers, Receptacles, Female Sockets Overview

The M50-3203845 is a Harwin ARCHER series socket assembly designed for surface mount technology. It features a dual in-line configuration with 76 positions arranged in two rows of 38 contacts each. The connector utilizes a 1.27 mm (0.05 inch) pitch and operates at right angles to the printed circuit board. Contacts are gold-plated phosphor bronze, rated for 1 A current. The housing is constructed from black liquid crystal polymer (LCP), offering UL 94 V-0 flammability ratings. It supports an operating temperature range from -40°C to +105°C and provides 1 GOhm insulation resistance.
