M22-5322005

Headers, Male Pins Overview

The Harwin M22-5322005 is a discontinued surface-mount board-to-board header featuring 40 positions in a dual-row configuration. It utilizes a 2.00mm pitch with square male pins made of phosphor bronze and gold plating. The housing is constructed from black polyamide (PA6T) nylon rated UL94 V-0. Key electrical ratings include 1A current per contact and an operating temperature range of -40°C to 105°C. The connector supports push-pull locking without a cover, offering mating stack heights of 4.6mm or 6.8mm.
