SurLok Plus™

Quick Lock and Press-to-Release Design, Plastic, RADSOK® Technology

Description

The SurLok Plus™ Compression Lug is a field-installable, high-reliability solution surpassing traditional compression lugs. Designed for ease of use, it utilizes standard industry crimp, screw, and busbar termination methods, eliminating the need for specialized torque tools.
Amphenol’s SurLok Plus™, an evolution of our original SurLok™, offers environmental sealing in more compact sizes. It features an innovative quick lock and press-to-release design for effortless operation. Enhanced with our cutting-edge R4 RADSOK® Technology, the SurLok Plus™ series is both space-efficient and robust, ensuring quick and secure connections.

The RADSOK® technology, central to the high amperage contact design, employs a stamped and formed high-conductivity alloy grid. This structure boasts high tensile strength, facilitating low insertion forces while maintaining a broad conductive surface area for optimal performance.

Our R4 RADSOK® is the result of three years of intensive research and development in laser welding copper-based alloys, marking a significant advancement in connector technology. Discover the SurLok Plus™ for a compact, efficient, and reliable connection solution.
