Connector Accessories

Amphenol PCD Backshells and Dust caps are designed for optimal performance in any application, especially harsh and demanding environments. Backshells provide strain relief, environmental protection, and EMI/RFI shielding at the termination area of virtually any connector. Dust caps provide sealing and dust protection at the connector interface while the connector is not in use. Backshells and other circular connector accessories are offered in Mil-spec, commercial, and custom types. Offering a base material of aluminum alloy, stainless steel, composite, silicone, or rubber and a wide range of plating options. Amphenol PCD connector accessories mate with Mil-spec and commercial connector series, including MIL-DTL-5015, MIL-DTL-26482, MIL-DTL-38999 and MIL-DTL-83723.

Strain relief, environmental protection and EMI/RFI shielding at the termination area of any connector. Support most applications with a full line of Military (MIL) specification, commercial, and custom solutions options.

Protect unmated connectors by keeping dust and other impurities out of the termination area when the connector is not in use. Available in QPL specification, commercial, and custom types for use with most circular connectors.

Backshells

Amphenol Pcd offers connector backshells that are RoHS-compliant and qualified to AS85049 specification. The backshells provide strain relief, environmental sealing, and EMI/RFI shielding at the termination of virtually any connector.

These backshells are available in both military (MIL) specification and commercial types for most any application and meet the SAE AS85049 standard. The base material is constructed of aluminum alloy, stainless steel, brass, or composite, complemented by a variety of finishes. Most Amphenol Pcd backshells meet or exceed RoHS and REACH compliant standards.

Adding to the versatility of these products is the variety of configuration options available. Offered in straight, 90-degree and 45-degree profiles, the backshells accommodate most of the cable routing requirements in today’s interconnect market.

Because of their rugged construction and versatility, Amphenol Pcd’s backshells are widely used in the military-aerospace and industrial markets.

Amphenol Backshells are available in several different types, designed for  optimum performance in the application or environment it will be used in. For example, in ground and naval applications, the robustness and environmental sealing may be more important, weight may be the prime consideration for Space and Aerospace applications. There are various families of backshells – some can be used without any additional protection, while other types of backshells are generally used with heat shrink boots or similar protection/strain relief mechanisms depending upon the specific requirements. Also, there are some clamps & nuts for the applications where varying degrees of strain reliefs and cable holding will suffice and weight savings is of higher importance.
