AMPHENOL RADSOK TECHNOLOGY
The RADSOK® High Amperage Electrical Terminal benefits the user from engineering, quality, and manufacturing viewpoints. RADSOK® technology is based upon a stamped and formed flat grid, twisted into a hyperbolic shape to provide secure and robust contact to the mating pin’s contact surface. Most Pin and Socket technologies rely upon spring (compressive) properties of the contact elements,which may weaken over time. Unlike other Pin and Socket solutions, the RADSOK® also utilizes the tensile strength properties of the flat stamped, copper alloy grid to provide high normal forces with a large socket-to-pin conductive surface area. This design provides a correspondingly low voltage drop and low temperature rise. Other tensile design products use round wires (instead of flat bands) in the hyperbolic shape, this significantly reduces the contact surface between pin and socket. Proven by millions of parts in the field, a RADSOK® electrical connection is economical and extremely reliable, with zero reported failures in properly designed applications. RADSOK® technology benefits can be summarized as: • HIGH RELIABILITY Unique RADSOK® design and construction technology create an electrical contact interface that exceeds typical interconnect requirements. Applications in aerospace, medical, industrial, automotive, mining, offshore, and other harsh environments depend on high reliability of the Amphenol RADSOK® technology. • LOW CONTACT ENGAGEMENT/SEPARATION FORCES The hyperbolic lamella socket contact construction distributes normal forces over a high percentage of the mating pin surface. This creates a smooth, even engagement effort. This force distribution also contributes to excellent performance in vibration applications with resistance to typical fretting corrosion. • LOW CONTACT RESISTANCE The large interface area between the socket lamella and pin surface result in very low contact resistance, enabling the RADSOK® contacts’ high current ratings compared to traditional power contact designs. • HIGH MATING CYCLE DURABILITY RADSOK® contacts with typical silver plating finishes have demonstrated survival of 20,000 mating cycles. Specialized plating and contact lubricants can extend cycle life to 200,000 matings or higher. Even with continuous exposure to harsh environmental abuse (salt, sand, and high humidity), RADSOK® contacts have been tested to maintain low contact resistance beyond 10,000 mating cycles.
