Samtec PCB SMT Double Row Straight Surface Pin Header 2.54 mm Pitch 40 Contacts Unshrouded TSM-120-02-L-DV

Samtec TSM-120-02-L-DV is a PCB SMT double row straight surface pin header designed for electrical engineering applications requiring robust, reliable connections with a 2.54 mm pitch and 40 contacts. The unshrouded header type allows versatile use in board-to-board and wire-to-board systems where space and pin count are critical factors.

This header features a high-quality liquid crystal polymer housing that provides mechanical strength, chemical resistance, and temperature stability from -55°C to 125°C. The phosphor bronze contacts plated with 0.25 µm gold plating on the posts and matte tin on the tails deliver excellent electrical conductivity and corrosion resistance, ensuring long-term durability in harsh industrial, commercial, and laboratory environments.

Rated for a maximum current of 7A and voltage up to 475V, this component suits medium power PCB connector applications. The mating pin length of 8.13 mm provides reliable mating with compatible sockets and strips, maintaining electrical integrity during vibrations and mechanical stresses.

The SMT surface mount design simplifies PCB assembly and reduces footprint, contributing to efficient manufacturing workflows in electronic component assembly. Its dual-row configuration allows compact placement of a large number of contacts, suited for complex electronic communication and power delivery circuits.

Features 40 gold-plated contacts for optimal conductivity and corrosion protection. Liquid crystal polymer housing supports high thermal and mechanical endurance. Suitable for board-to-board and wire-to-board connector systems.

Wide temperature range from -55°C to 125°C adapts to various environments. Surface mount technology with solder termination supports automated assembly processes.

This header is ideal for industrial machinery, telecommunications, electronic instrumentation, automotive electronics, and other applications where tight, reliable connections with high current capacity are necessary. Samtec’s TSM series is known for quality and precision, facilitating performance in complex electrical assemblies.
