Samtec SMS Series Straight Through Hole PCB Socket 40-Contact 2 Row 1.27 mm Pitch Solder SMS-120-01-G-D

The Samtec SMS-120-01-G-D is a high-performance PCB socket engineered for electronic and industrial applications where reliable connectivity is essential. This socket features 40 female contacts arranged in 2 rows, utilizing a micro socket strip configuration. With a 1.27 mm pitch, it accommodates compact designs and provides board-to-board connections that ensure signal integrity and mechanical security.

Its straight through-hole mounting style allows for secure placement on printed circuit boards and enables robust soldering. The housing is constructed from liquid crystal polymer, known for its strength and resistance to high temperatures, supporting operating ranges from -55°C up to 125°C. Contacts are made from bronze and receive gold plating, guaranteeing both high conductivity and remarkable resistance to corrosion, which is critical for long-term electronic reliability.

The SMS Series supports a maximum current rating of 12 A, suitable for various industrial and laboratory environments where robust power or signal transfer is needed. Its board-to-board connector system, vertical orientation, and 2.54 mm row pitch facilitate integration with standard PCB layouts. Ideal for both single and double row designs, this socket can be used in assemblies requiring up to 100 pins in total.

Tiger Buy™ contact system further enhances performance by optimizing contact interface geometry, resulting in minimal electrical resistance and secure mating. The termination method is through-hole, which simplifies soldering and offers enhanced mechanical hold for assemblies exposed to vibration or frequent handling.

Applications include industrial controls, instrumentation, communications equipment, measurement devices, laboratory hardware, and custom PCB assemblies requiring high-density and reliable pin connections. With its blend of material quality, electrical rating, and design flexibility, the Samtec SMS-120-01-G-D PCB Socket is a preferred choice for engineers and designers engaged in advanced electronics manufacturing and prototyping.
