M55-6005042R

Headers, Receptacles, Female Sockets Overview

The M55-6005042R is a 50-position board-to-board and mezzanine connector from the Harwin Archer Kontrol series. It features a 1.27 mm pitch with two rows of contacts designed for vertical surface mount technology (SMT) termination. The receptacle utilizes gold-plated phosphor bronze contacts housed in a liquid crystal polymer (LCP) shell rated UL 94 V-0. Electrical ratings include a current capacity of 1.2 A and a voltage rating of 100 VAC. The unit operates within a temperature range of -55°C to +125°C and provides an insulation resistance of 10 GOhms.
