M22-5321646R

Headers, Male Pins Overview

The M22-5321646R is a surface mount rectangular header connector from the Harwin M22 series. It features a 2.00 mm pitch and a 1+1 row configuration with 16 positions (totaling 32 contacts). The connector utilizes gold-plated phosphor bronze contacts for reliable electrical performance. Designed for board-to-board applications, it employs a push-pull locking mechanism to ensure secure mating. The housing is constructed from black polyamide (PA6T) material rated UL94 V-0 for flame resistance. It supports a stacking height of 4.6 mm or 6.8 mm and operates within a temperature range of -40°C to +105°C.
