A8504952S10W is a QPL connector accessory backshell designed for use with military circular connectors. This strain relief clamp backshell features a spin coupling design with lock wire holes to prevent accidental decoupling, and is constructed from aluminum alloy with cadmium olive drab over electroless nickel finish. The backshell provides strain relief, environmental protection, and EMI/RFI shielding at the termination area of the connector. Common applications include military, aerospace, and harsh environment systems where reliable cable termination and protection are required.
