Samtec Straight Surface Mount PCB Socket, 40 Contacts, 2 Row, 0.8 mm Pitch, Solder ERF8

The Samtec ERF8-020-05.0-L-DV-K-TR is a high-performance straight surface mount PCB socket, engineered for applications requiring robust board-to-board interconnection. With a compact dual-row configuration and 40 gold-plated bronze contacts spaced at a precise 0.8 mm pitch, this connector provides reliable electrical continuity and mechanical stability vital for dense circuit layouts in modern electronics.

This socket is designed to support high data transmission speeds and ensures signal integrity across demanding industrial, commercial, and high-speed digital environments. The gold-plated contact surfaces enhance corrosion resistance and minimize contact resistance, making the connector suitable for use in circuits operating up to 318 V and 2.2 A. Its flat surface mount configuration allows for straightforward and secure PCB assembly, while the straight orientation ensures simplified integration into vertical stacked designs.

The housing is constructed from liquid crystal polymer, a material known for its durability and thermal resilience, supporting continuous operation across a temperature range from -55°C to 125°C. The connector provides a stacking height of 18 mm, with the Edge Rate® design facilitating smooth insertion, wear resistance, and long operational life. Typical use cases include high-performance computing systems, instrumentation, industrial automation controllers, and other electronics where signal density and long-term reliability are critical.

Supporting both high frequency and power applications, the dual-row setup with 4.5 mm row pitch maximizes space efficiency for designers requiring reliable multi-point interconnects. The solder termination ensures stable mounting on the PCB, while the board-to-board connector system improves modularization and ease of assembly in complex devices.

This Samtec PCB socket is part of the proven ERF8 series, recognized for supporting Edge Rate® rugged high-speed solutions and compatible with stacking positions beyond 18 mm in specialized layouts. The product is also engineered to maximize contact smoothness and minimize insertion force, which is essential for reliable high-cycle applications.

The ERF8-020-05.0-L-DV-K-TR finds application in electronics manufacturing, industrial automation, test and measurement systems, and other high-reliability environments where space-saving, high-frequency, and robust electrical connections are required.
