FAQs
Installation hinges on correct mating alignment and secure retention. The 1/3 Bayonet coupling provides rapid, reliable engagement when the backshell is oriented correctly (W). Use the straight adaptor for panel mounting and ensure the 41-contact receptacle aligns with the mating plug through a proper mating cycle. Delivered with connector, installation time is reduced and mating integrity is improved in vibration-prone environments.
Yes. The 85100A2041SW50 is a MIL-DTL-26482 SI qualified square flange receptacle with 41 contacts and a straight backshell adaptor, designed to mate with compatible MIL-DTL-26482 plugs. Its W orientation and cadmium-plated aluminium shell support robust, gender-matched connections while simplifying integration in aerospace and industrial systems.
The receptacle excels in aerospace, defense, and rugged industrial automation where high-density signal and power transfer are required under harsh conditions. Its 41-contact arrangement, solder cup contacts, and wide operating range enable reliable harness connections in aircraft, vehicle platforms, and outdoor automation enclosures, reducing maintenance cycles and boosting uptime.
Key standards include MIL-DTL-26482 SI qualification for rugged interconnect performance and REACH compliance for environmental responsibility. Cadmium plating provides corrosion protection on an aluminium shell, which is relevant for durability in challenging environments. Verify program requirements regarding cadmium use and potential substitutes where restricted by local procurement policies.
