M80-4034242

Headers, Receptacles, Female Sockets Overview

The M80-4034242 is a Datamate J-Tek series board connector manufactured by Harwin Inc. It features a 42-position configuration arranged in two rows, providing a 21+21 pin layout. The component utilizes a 2 mm (0.079 inch) pitch and is designed for vertical through-hole mounting with solder termination. Contact materials consist of beryllium copper with gold plating on the mating interface and tin plating on the tail. The housing is constructed from black polyphenylene sulfide (PPS). Electrical ratings include a current capacity of 3 A and an insulation resistance of 100 MOhms. The operational temperature range spans from -55°C to +125°C.
