Backshells

Amphenol PCD Backshells offer strain relief, environmental protection, and 360° EMI/RFI shielding at the termination area of virtually any circular connector. These connectors feature a base material constructed of aluminum alloy, stainless steel, brass, or composite and a variety of finishes such as black zinc nickel, cadmium, electroless nickel, anodized black, passivated, and more. Amphenol PCD Backshells have custom designs available and meet or exceed RoHS/REACH compliance standards. Available in both military specifications and commercial types for any application, these backshells meet the Society of Automotive Engineers (SAE) AS85049 standard.
