The M85049 series regroups all our military standard QPL backshells. M85049 backshells are designed to fit the main circular connectors used in our industry (Mil-DTL-26482 series II, 83723 series 1 & 3, 38999 series I, II, III & IV); they are qualified for aluminum, stainless steel or composite material (many plating proposed).

Two self-locking technologies were developed: a detented system and the SUNBANK Self-seating mechanism that exceeds the vibration requirements. A free rotatable coupling is also available.

Qualified for multiple EMI/RFI designs, M85049 SUNBANK backshells are available in banding and crimping platforms for overall shielding, dual EMI ring for overall and individual shielding. The bodies are specifically designed to optimize weight and robustness. The Self-seating locking option offers lighter weight and lower profile backshell than a detented system.
