Overview
The Amphenol 97-3057-1012 is a MIL-spec circular connector cable clamp designed for use with standard cylindrical connectors featuring 20/22-size shells. This strain relief clamp meets MS3057A specifications and is widely used in factory automation, robotics, machine tooling, and aerospace applications requiring secure, reliable cable strain relief.
Key Features
- MS3057A Compliance – Meets MIL-DTL-5015 (SAE-AS50151) military connector standards for proven durability and compatibility.
- Floating Clamping Halves – Both halves float independently for maximum strain relief and protection against cable damage.
- Zinc Alloy Construction – Die-cast zinc alloy shell with black zinc plating provides corrosion resistance and mechanical strength.
- Versatile Cable Support – Suitable for jacketed cable, unjacketed cable, and wires protected by tubing.
- Standard 20/22 Shell Size – Compatible with all standard cylindrical connectors using size 20 and 22 shells.
- 19.05 mm Cable Diameter – Accommodates 0.75-inch (19.05 mm) cable and wire bundles.
