Samtec HTST Series Straight Surface PCB Header, 20 Contacts, 2.54 mm Pitch, 2 Rows, Shrouded HTST-120-01-L-DV

The Samtec HTST-120-01-L-DV is a high-reliability straight surface PCB header designed for use in electronic assemblies requiring board-to-board connectivity. This model is part of the distinguished HTST series and features 20 gold-plated male contacts arranged in two precisely aligned rows with a 2.54 mm pitch, providing high signal density and consistent electrical performance.

Its housing is constructed from liquid crystal polymer, ensuring mechanical strength and thermal stability, which is particularly valuable for industrial and high-temperature applications. The contacts are manufactured from phosphor bronze and finished with gold plating, providing not only excellent conductivity but also resistance to corrosion and wear over multiple insertion cycles.

The connector is shrouded, preventing incorrect mating and providing additional mechanical protection to the contacts. With a contact current rating of up to 3.4 A and a voltage rating of 600 V, this header is equipped to handle a wide range of electronic and industrial equipment requirements. Its solder termination is compatible with modern reflow soldering processes, contributing to manufacturing efficiency.

The HTST-120-01-L-DV supports an operating temperature range from -55°C up to 125°C, enabling reliable performance even in harsh environments. The surface mount design aligns with automated assembly practices, enhancing production throughput in high-volume applications. This header is particularly suited for demanding industrial, instrumentation, automation, and communication equipment, as well as advanced consumer and commercial electronics.

Typical applications include backplane connections, signal interconnects in industrial control panels, embedded systems, and high-density PCB layouts where secure, shrouded and pitch-consistent headers are essential for robust operation. Its precise polarization notch and shrouded design help reduce assembly errors, making it ideal for automated systems and mission-critical hardware interfaces.
