M80-5S20642MQ

Overview

The M80-5S20642MQ is a Datamate J-Tek header connector manufactured by Harwin Inc. It features a 20-position, dual-row configuration with a 2mm (0.079 inch) mating pitch. Designed for surface-mount technology, it utilizes male pin contacts made of phosphor bronze with gold plating on the mating interface and tin plating on the tail. The housing is constructed from black polyphenylene sulfide (PPS) reinforced with glass fiber, rated UL94 V-0. Key mechanical specifications include an insulation height of 5.60mm and a contact length of 3.30mm. The connector supports a rated current of 2.2A and operates within a temperature range of -55°C to 125°C.
