Heavy equipment EV HEV Amphenol SLPIPB35BSB1EH SurLok Plus compression lug with RADSOK R4 technology

Amphenol SurLok Plus Series

Product Overview
The Amphenol SurLok Plus compression lug is a field-installable, highly reliable alternative to common compression lugs. It utilizes industry-standard crimp, screw, and busbar termination options, eliminating the need for special torque tools. The SurLok Plus is an environmentally sealed version of the original SurLok, available in smaller sizes, and features a quick lock and press-to-release design. Incorporating the latest R4 RADSOK Technology, it offers a compact, quick mating, and robust product line. The RADSOK high amperage contact technology uses a stamped and formed, high conductivity alloy grid to achieve low insertion forces while maintaining a large conductive surface area. The R4 version represents advancements in laser welding copper-based alloys. Key markets and applications include Energy Storage, EV/HEV, Process Control/Automation, and Heavy Equipment. The connector design ensures a definitive electrical and mechanical connection with an integral latching system. Housings are made from durable thermoplastic with excellent dielectric and mechanical properties, meeting RoHS compliance. Contacts are derived from quality copper alloy for electrical reliability. The series is certified to UL1977/4128 and TUV 2PfG2740.
