AS85049 Backshells

as85049 backshellsM85049/AS85049 backshells are coupled to the connector body to support and strain relieve the cable entry at the rear of the connector. Depending on type they may also provide a seal and EMI/RFI shielding. They are available in many configurations and styles to suit MIL-DTL-D38999, MIL-DTL-26482, MIL-DTL-83723 and MIL-DTL-5015 connectors. Strain relief clamps are available in either straight or 90-degree variants. Coupling is either self-locking or non self-locking.

Backshells for Military and Aerospace applications are governed by the SAE and the now ratified AS85049 standard. All existing M85049 documents have been superseded by the new standard. Follow our 'how to order 85049' guide.
