SurLok Plus™
The SurLok Plus™ compression lug is a eld installable,
highly reliable alternative to common compression
lugs. Using industry standard crimp, screw, and busbar
termination options, thus eliminating the need to purchase
special torque tools.
Amphenol’s SurLok Plus™ is an environmentally sealed
version of our original SurLok™ but 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 utilizes
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 R4 version of the RADSOK® represents the culmination
of three years of research and development in laser welding
copper based alloys.
Features:
• R4 RADSOK® Technology
• IP67 rated
• Touch Proof
• Quick lock and press-to-release design
• “Keyway” design to prevent incorrect mating
• 360° rotating plug
• Various termination options (Threaded, Crimp, Busbar)
