M80-4002842

Headers, Receptacles, Female Sockets Overview

The M80-4002842 is a Datamate J-Tek series connector header manufactured by Harwin Inc. It features a vertical through-hole mounting style with 28 positions arranged in two rows. The contact pitch is 2.00mm (0.079 inches), and the row spacing is also 2.00mm. The contacts are male pins made of phosphor bronze with gold plating on the mating surface. The housing is constructed from black, glass-reinforced polyphenylene sulfide (PPS) rated UL94 V-0. It utilizes jackscrew fixing for secure attachment and operates within a temperature range of -55°C to 125°C.
