M52-5050445

Headers, Receptacles, Female Sockets Overview

The Harwin M52-5050445 is a 4-position receptacle connector from the Archer M52 series, designed for board-to-board applications. It features a 1.27mm (0.050 inch) pitch and utilizes surface mount termination for PCB integration. The contacts are gold-plated phosphor bronze sockets with a rectangular shape, housed in black polyamide insulation rated UL94 V-0. Rated for 500V and operating between -40°C and +105°C, it ensures reliable electrical performance in demanding environments.
