Amphenol Industrial RADSOK® Connectors

Amphenol Industrial RADSOK® Connectors upgrade many core connectors by simply adding the RADSOK advantage. RADial SOcKet (RADSOK) is a socket cylinder within a female contact that has several equally spaced longitudinal beams twisted into a hyperbolic shape. As the male pin is inserted, axial members in the female half deflect, imparting high current flow across the connection with minimal voltage loss. The configuration ensures a large, coaxial, face-to-face surface area engagement and is ideal for crimp termination applications requiring repeated mating cycles and high current with a low millivolt drop. Amphenol connectors using RADSOK technology include Amphe-GTR Reverse Bayonet Connectors for Power Applications, PowerBus Amphe-PD™ Connectors, Amphe-Power® Connectors, board level connectors such as PowerBlok™, RADSERT™, and PGY™, SurLok Connectors, and Helios H4 Solar Connectors.
