M50-3612042R

Headers, Male Pins Overview

The Harwin M50-3612042R is a surface-mount header connector from the Archer M50 series. It features 40 positions arranged in a dual-row configuration with a 1.27mm pitch. The connector utilizes square male pins made of brass, finished with gold plating on the mating interface and tin on the tail. Designed for board-to-board or cable applications, it operates within a temperature range of -55°C to 105°C. The unit has a rated current of 1A and voltage of 250V, with UL94 V-0 black thermoplastic insulation.
