M80-7542042

Overview

The Harwin M80-7542042 is a Datamate L-Tek series power-to-board header connector designed for through-hole mounting. It features a 20-position configuration arranged in two rows of ten, providing a total of twenty male pin contacts. The connector utilizes a 2 mm pitch and includes a 4.5 mm tail length to facilitate board-to-board or wire-to-board interconnections. Constructed with phosphor bronze contacts that are gold-plated at the mating interface, the unit ensures reliable signal transmission. The housing is made from black polyphenylene sulfide (PPS), offering high thermal stability and mechanical strength.
