Samtec TMM Series Straight Through Hole Pin Header 40 Contacts 2 mm Pitch 2 Row Unshrouded TMM-120-01-G-D

Samtec TMM-120-01-G-D is a low profile, straight through hole pin header from the TMM Series designed for printed circuit board (PCB) applications. It features 40 male contacts arranged in 2 rows with a 2 mm pitch, facilitating tight spacing and efficient board integration.

The housing is made from black Liquid Crystal Polymer (LCP), offering excellent mechanical strength and electrical insulation. The phosphor bronze contacts are plated with gold (0.5 μm on posts and 0.075 μm on tails) to ensure reliable electrical conductivity and resistance to corrosion.

Operating within a temperature range from -55°C to +125°C, this header is suited for demanding industrial and electronic applications, including board-to-board and wire-to-board connections in telecommunications, industrial automation, and computing hardware.

The through hole mount type provides strong mechanical retention and electrical connectivity, with a tail pin length of 3.5 mm and mating pin length of 3.2 mm. It supports up to 3.9A current and withstands voltages up to 500V, complying with industry standards except specific approvals which are not listed for this model.

The product is unshrouded, allowing easy inspection and solder access, and is designed to be compatible with several Samtec socket series for flexible system designs. Features a 2 mm pitch and 2 rows for compact board mounting.
