Robust Amphenol SLPIRC50CPSO4 compression lug with quick mating and environmentally sealed SurLok Plus design
Amphenol SurLok Plus Series
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. 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, SurLok Plus is a compact, quick mating, and robust product line. The RADSOK high amperage contact technology uses the high tensile strength properties of a stamped and formed, high conductivity alloy grid to produce low insertion forces while maintaining a large conductive surface area.
The SurLok Plus series is designed for applications in Energy Storage, EV/HEV, Process Control/Automation, and Heavy Equipment.
