Compact and robust Amphenol SLPHIRCBPNR1 SurLok Plus compression lug with low insertion force design
Amphenol SurLok Plus Series
Product Overview
The Amphenol SurLok Plus compression lug is a field-installable, highly reliable alternative to common compression lugs, utilizing industry-standard crimp, screw, and busbar termination options. It is an environmentally sealed version of the original SurLok, available in smaller sizes, and features a quick lock and press-to-release design. Incorporating RADSOK Technology, the SurLok Plus is a compact, quick-mating, and robust product line designed for high amperage applications. 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 SurLok Plus series is suitable for markets including Energy Storage, EV/HEV, Process Control/Automation, and Heavy Equipment.
