FAQs
The 85100A2236SY50 is a MIL-DTL-26482 style square flange receptacle with a straight backshell adaptor and 36 solder cup contacts. Compatibility hinges on matching shell size 22, 36-contact configuration, and the 1/3 bayonet coupling. For mating, use a corresponding Souriau 851 series receptacle that shares the same shell size and layout.
Key specs include 36 solder cup contacts, socket (female) contact gender, 1/3 bayonet coupling, aluminium shell with cadmium plating, 44 mm length, 40 mm width and height, and a 36‑cavity layout. Operating temperature ranges from -40 °C to 125 °C. It is REACH compliant and delivered as a loaded receptacle with connector option.
Yes. This model is MIL-DTL-26482 SI qualified, offering proven performance under vibration and mechanical stress. The 36‑cavity, 1/3 bayonet coupling design provides secure mating, while the aluminium shell and cadmium plating contribute to mechanical durability and corrosion resistance in harsh environments.
The product carries MIL-DTL-26482 SI qualification and REACH environmental compliance. It uses cadmium plating and an aluminium shell to balance durability and weight, but users should verify any regional restrictions on cadmium use and ensure compatibility with specific CE or IP requirements for their application.
Ensure mating to a compatible 851 series receptacle with the same shell size and 36-contact layout. Fully engage the 1/3 bayonet coupling to maintain vibration resistance, and route wiring via the Y orientation backshell for compact harness routing. Regular inspection of solder cups and contact surfaces, along with selecting the cadmium-plated aluminium shell for corrosion protection, supports longer service life and reduced maintenance.
