Samtec FTSH Series Straight Surface Pin Header, 40 Contacts, 1.27 mm Pitch, 2 Row, Unshrouded, Surface Mount FTSH-120-04-L-D

The Samtec FTSH-120-04-L-D is a high-density straight surface mount pin header featuring 40 male contacts arranged in two rows at a 1.27 mm pitch. This connector is engineered for wire-to-board applications and is ideal for signal interfacing and power distribution in electronics, embedded systems, and industrial automation.

The housing material is liquid crystal polymer, providing excellent mechanical strength, dimensional stability, and resistance to high temperatures. Phosphor bronze contacts ensure reliable electrical performance, while gold plating delivers superior conductivity and minimizes signal loss and contact corrosion.

The FTSH-120-04-L-D supports up to 3.4A per contact and operates within a wide temperature range from -55°C to 125°C, making it suitable for demanding industrial, laboratory, and embedded system use. Its solder tail termination affords secure attachment to printed circuit boards, and the straight orientation allows for precise placement and alignment during PCB assembly.

Unshrouded pin headers are widely used in prototyping, assemblies, and custom PCB layouts, offering flexibility in connector design. This header is equipped with 0.1 mm tail pin length and a mating pin length of 3.81 mm, delivering robust connections for both low- and medium-power applications.

The Samtec FTSH series pin header is compatible with Extended Life Product™ technology and is available with various post heights and horizontal/vertical configurations in the series. Cost-saving flash gold plating options and hot-pluggable versions may also be accessible within the FTSH product family for specialized requirements.

Typical use cases include industrial controllers, instrumentation, laboratory equipment, commercial electronics, embedded system boards, PCB development, and automation systems. Designed for wire-to-board connections with reliable phosphor bronze contacts.
