Backshell Clamps

Amphenol PCD Backshell Clamps help to tidy up the cable after termination and provide strain relief at the termination area. The clamps are offered in environmental and non-environmental options, as well as EMI/RFI. The components are available in black zinc nickel, adding to the existing finishes in olive drab gray cadmium, tin, or nickel with a variety of shell sizes 11 through 48. Amphenol PCD Backshell Clamps meet MIL-DTL-38999, MIL-DTL-26482 Series II, MIL-DTL-83723 Series I and II, MIL-DTL-24308, and MIL-DTL-83513.
