The 97-3057-1012(621) is an MS3057A type cable clamp designed to provide strain relief for Amphenol 97 series connectors. It is specifically compatible with shell sizes 20 and 22 and features 1-3/16-18 threads. The design incorporates two floating clamping halves to ensure maximum strain relief for jacketed cables or wires protected by tubing. This model features a RoHS-compliant black zinc alloy finish. For applications involving unjacketed cables, the use of a corresponding MS3420 bushing is recommended to ensure secure termination.
