Samtec QFS Series 104-Contact Straight Surface PCB Socket, 2 Row, 0.635 mm Pitch, Solder, 300V, 15.7A QFS-052-04.25-L-D-A

The Samtec QFS-052-04.25-L-D-A is a high-performance PCB socket designed for demanding electronic and industrial applications. Featuring 104 contacts in a straight surface configuration with two rows and a fine 0.635 mm pitch, this connector enables reliable high-density board-to-board connections above industry standards. Its solder termination ensures stable and robust electrical and mechanical performance throughout operation.

This connector is engineered with liquid crystal polymer housing for strength and temperature stability, supporting voltages up to 300V and currents up to 15.7A. Gold-plated bronze contacts guarantee superior conductivity, corrosion resistance, and long-term reliability, making the socket ideal for signal integrity and rugged performance. The stacking height of 10 mm aligns it well with multi-board systems where space and precise alignment are critical.

Ideal for use in high-speed circuit designs, industrial instrumentation, communications equipment, advanced PCB development, and commercial electronics requiring secure, high-density connections. Its board-to-board system is optimized for environments where both compact layout and performance are essential. The connector's dual-row design increases circuit capacity, and its surface mount orientation supports efficient automated PCB assembly. Its straight orientation allows consistent mechanical fit within system layout requirements.

The Samtec QFS Series incorporates advanced engineering including Q2™ high-speed rugged ground-plane socket strips and optional guide posts for alignment in complex designs. With operation temperatures ranging from -55°C to 125°C, this connector is suitable for broad industrial and laboratory environments. The product also meets modern industry standards for PCB connectors and achieves high data rates for advanced electronic systems.

Typical use cases include industrial control panels, precision instrumentation, automation, telecommunications, medical devices, and laboratory equipment - any scenario requiring secure, durable, and high-density board-to-board connections.
