Product Description
This EMI shielded backshell is selected to terminate cable braid around the rear of a D38999 or compatible circular connector. Depending on the design, the assembly may use a banding platform, clamp, shield sock or environmental boot to create a controlled low-impedance shield transition while also supporting cable strain relief. Selection requires the connector series, shell size, rear thread, cable OD, braid construction, exit angle and finish. Shielding performance depends on the complete connector, backshell, cable and enclosure design. Submit the mating connector and cable construction for a compatible accessory and installation-tool quotation.
EMI performance is system-dependent. Do not treat this generic listing as a guaranteed shielding value or qualification claim; final performance follows the selected design and test evidence.
