FAQs
The receptacle is designed for panel mounting with a straight backshell and adaptor. Use the 41-contact, Solder Cup configuration and align with the mating connector via the 1/3 bayonet coupling. Ensure cadmium-plated aluminium shell protection is intact and that the backshell is properly seated to maintain environmental sealing during installation.
MIL-DTL-26482 SI qualification indicates superior vibration resistance and reliability in demanding conditions. Combined with a wide operating temperature range (-40 °C to 125 °C), cadmium plating for corrosion resistance, and a robust aluminium shell, the 85100AC2041SW50 is well-suited for avionics, aircraft, and defense applications.
Yes. The 85100AC2041SW50 is part of the Souriau 851 family and uses standard 1/3 bayonet coupling with a square flange receptacle design. It supports the same 41-circuit layout and solder-cup contacts, allowing straightforward interchangeability with compatible Souriau connectors and accessories.
The product carries MIL-DTL-26482 SI qualification for high-reliability performance and REACH compliance for environmental safety. These certifications support compliance in regulated aerospace and defense programs while ensuring body and contact integrity under service conditions.
The 85100AC2041SW50 offers reduced maintenance due to robust corrosion resistance, high mating reliability, and a long service life in harsh environments. Its 41-circuit density enables compact harness designs, lowering assembly time and wiring complexity, while SI qualification minimizes field failures in critical missions.
