Amphenol MS 3057-10A Military Circular Connector

MS3057-10A is a black aluminum-alloy cable clamp (strain-relief accessory) designed for Amphenol MS3057 military circular connectors, sized for shell insert 18. This accessory attaches to the connector housing to secure the cable at the entry point and relieve bending and pull forces, preserving conductor integrity in rugged environments. It is listed as an MS3057 family backshell/cable clamp component with shell insert 18, made from aluminum alloy, and is marketed under Amphenol Aerospace Operations. The part is commonly described by distributors as a cable clamp in size 18 (color black), offered for MS3057-series assemblies where reliable cable retention is required. Typical applications include aerospace, defense, and other harsh-environment wire harness installations that employ MS-series circular connectors for power and signal lines, where a dedicated clamp provides dedicated strain relief without altering the mating connector’s interface. By using a dedicated clamp, technicians can secure harnesses and maintain routing integrity at the MS3057 connection point, contributing to robust overall connector performance in demanding operating conditions.
