Tri-power with RADSOK® Technology

Amphenol has combined the reliability of D38999 connectors with the high-current RADSOK® contact design. The Amphenol Power Connectors incorporate the proven design of the MIL-DTL-38999 Series III Tri-Start connectors with the evolving technology of the High Power RADSOK® contacts. This newly designed product is the future of power connectors enabling customers to choose contacts ranging from 70 to 120 amps (240 to 620 amps per connector) allowing more power in a smaller connector. Using standard shell sizes for 38999 connectors will allow the Power Connectors to mate to existing mounting holes without changing the customer’s original design. In addition, Amphenol offers oversized 38999-style shells which are able to provide more power and amperage, while maintaining the proven, trusted MIL-DTL-38999 style design.
