M20-9990646

Headers, Male Pins Overview

The M20-9990646 is a vertical pin header from the Harwin M20 series, designed for board-to-board and board-to-wire interconnections. It features a 2.54 mm pitch with six positions in a single row configuration. The connector utilizes square pins with a tin surface finish and is constructed with a polyamide (PA6T) housing rated UL94 V-0. Designed for through-hole mounting, it supports a maximum current of 3A per contact and operates within a temperature range of -40°C to +105°C.
