Amphenol LTD Rhino 38999 Single-Pole High-Power Connectors combine the benefits of Mil-DTL-38999 Series III circular connectors with hyperbolic contacts that extend the boundaries of high-power connector technology. These connectors use RADSOK contacts to create an electrical interface that exceeds typical interconnect requirements. The hyperbolic socket contact construction distributes normal forces over a high percentage of the mating surface, ensuring a smooth and even engagement force with high performance under vibration. The large surface area of the socket contact also results in low contact resistance, enabling much higher current ratings compared to other power contact designs.
