Samtec SFMH Series Horizontal Surface PCB Header, 50 Contacts, 1.27 mm Pitch, 2 Row, Shrouded SFMH-125-02-L-D-LC

The Samtec SFMH-125-02-L-D-LC is a horizontal surface mount PCB header designed for high-density electronic applications. Featuring a shrouded design and 50 contacts arranged in two rows, this header provides secure board-to-board connectivity with a precise pitch of 1.27 mm. Its compact form factor and robust construction make it ideal for use in industrial, automation, communication, and instrumentation systems where reliable signal transmission and space-saving are essential.

The housing is manufactured from black liquid crystal polymer, offering superior mechanical strength and performance in varied environments. Contacts are made of phosphor bronze, plated with silver and tin, which ensures excellent conductivity and corrosion resistance. The shrouded feature helps to protect the contacts and facilitate reliable mating, reducing the risk of misalignment during assembly and maintenance.

With a current rating of up to 2.6 amps per pin, the SFMH-125-02-L-D-LC supports robust electrical requirements for modern circuit boards. The header is configured for surface mount, enabling straightforward, automated placement on PCBs, and further enhancing manufacturing efficiency. Solder termination provides strong retention and minimizes connectivity issues even in demanding operating conditions.

This PCB connector operates from -55°C to 125°C, suitable for both commercial-grade and harsh industrial environments. The 1.27 mm pitch is specifically designed for dense boards, supporting high signal counts without excessive board real estate consumption. The male contact gender aligns with typical board-to-board connector systems, especially in control panels, measurement devices, and embedded computing modules.

Key features include reliable shrouded construction, two-row contact configuration, surface mount compatibility, and high-quality material selection for both housing and contacts. These attributes make the Samtec SFMH series a trusted choice for engineers looking to ensure stable interconnections in critical electronic assemblies.

Applications span instrumentation, manufacturing equipment, industrial control systems, communication infrastructure, laboratory electronics, and high-speed digital processing boards.
