97-3057-1007(621) – AMPHENOL

The 97-3057-1007(621) cable clamp, manufactured by Amphenol, is a rear-release environmental backshell designed for circular connectors conforming to MIL-DTL-5015 specifications, specifically size 12SL and 14S shells. It provides strain relief and environmental sealing for cable entries. The 3/4-20 UNEF thread facilitates secure attachment to compatible connector shells. Constructed from a corrosion-resistant aluminum alloy, typically with a conductive finish like olive drab cadmium plating, the clamp accommodates a range of cable diameters as determined by the insert configuration. This backshell is designed to maintain electrical continuity between the cable shield and the connector shell, minimizing EMI/RFI leakage. Installation requires appropriate tooling for tightening the backshell to the specified torque to ensure proper sealing and strain relief.
