The M80-8400401 is a 4-position female socket connector from the Datamate L-Tek series by Harwin Inc. It features a 2 mm (0.079 inch) pitch and is designed for through-hole mounting on printed circuit boards. The contacts are gold-plated phosphor bronze, rated for 3 A current and 120 V voltage. The housing is constructed from black polyamide with a UL 94 V-0 flammability rating. Operating temperatures range from -55°C to +125°C.
Verify component authenticity against official Harwin documentation before integration. Confirm that the specific lot matches the required RoHS compliance status and material specifications. Ensure storage conditions maintain integrity of the gold plating and polyamide housing prior to assembly.
Select this model when a low-profile, two-row female header is required for board-to-board or cable connections. The 2 mm pitch suits dense layouts. Verify mating compatibility with corresponding Datamate J-Tek male pins. Consider thermal requirements as the unit operates within standard industrial temperature ranges.
This component belongs to the Datamate L-Tek family, characterized by compact form factors and reliable performance in harsh environments. It serves as a critical interface element in modern electronics, facilitating secure electrical connections between rigid PCBs and flexible wiring harnesses.
