SurLok Plus® Heavy-Duty Power Connectors

Amphenol Industrial SurLok Plus^® Heavy-Duty Power Connectors are IP67-rated, field installable, highly reliable connectors offering industry-standard crimp, screw, and busbar termination options. No special torque tools are required. The SurLok components feature a quick-lock and press-to-release function and multiple keyways. Amphenol SurLok Plus Connectors incorporate the R4 RADSOK^® technology. This technology utilizes the high tensile strength properties and forms a high-conductivity alloy grid to produce low insertion forces while maintaining a large conductive surface area.
