Product Description

The Samtec EHF-125-01-L-D-SM-LC is a straight surface mount PCB header engineered for demanding electronic applications requiring a reliable wire-to-board solution. With 50 phosphor bronze, gold-plated male contacts arranged in 2 rows, this header is suitable for high-density circuit layouts and offers exceptional signal integrity.

Its fine 1.27 mm contact pitch allows integration into compact modern PCBs, optimizing real estate in advanced circuitry. The shrouded design improves physical alignment during mating, considerably reducing the likelihood of misconnection, while providing increased cable retention security when paired with appropriate cable assemblies.

This header is constructed using Liquid Crystal Polymer, offering the durability and high temperature stability essential for reflow soldering. Its wide operating temperature range from -55°C to 125°C makes it suitable for industrial and instrumentation environments where thermal stresses are prominent.

The surface mount termination simplifies soldering onto the PCB, and a polarisation notch is provided for correct orientation during assembly, further reducing potential assembly errors. The wire-to-board connector system is ideal for use in signal transmission, data processing hardware, office equipment, and other high-density switching and control systems.

Gold-plated contact surfaces ensure excellent conductivity and provide superior corrosion resistance in electrically demanding contexts. The EHF-125-01-L-D-SM-LC header is fully compatible with typical through-hole, right-angle, and surface mount applications in the EHF series.

Typical industrial use cases include automation equipment, communication modules, data acquisition units, and laboratory instrumentation where compact, durable connections are critical.
