Feature → Business Impact → Application: The 85100E2232S50 uses a square flange receptacle with a backnut, aluminum shell, and cadmium plating to deliver durable, corrosion-resistant connectivity in harsh environments, reducing maintenance cycles and extending service life in aerospace and industrial installations. This design enables quick, secure mating through a 1/3 bayonet coupling, speeding assembly on crowded panels while maintaining reliable electrical contact. The 32 solder cup contacts support high-density signal and power routing, improving panel density and enabling more capable equipment in compact enclosures often found in automated plants and aircraft systems. Compatibility with 32 cavities and a straight backshell simplifies harness routing and interchangeability with existing Souriau 851-series ecosystems, lowering total cost of ownership and easing supplier qualification. The operating range of -40 °C to 125 °C ensures performance in extreme environments, while REACH and cadmium plating address regulatory and industry standards for regulated programs. Deployment with this connector minimizes risk in critical deploy-to-field programs and supports long-term procurement plans.

FAQs
Install using the backnut and straight backshell to secure the receptacle against the panel. The 1/3 bayonet coupling provides fast, reliable mating, and the connector orientation is N to align with the receiving plug. Ensure the shell is cadmium-plated for corrosion resistance and verify REACH compliance for regulatory needs.
The assembly supports 32 solder cup contacts in a 32-cavity layout, aluminum shell size 22, 34.5 mm length, 40 mm width, 40 mm height, and weighs 54.7 g. Operating temperature ranges from -40 °C to 125 °C. The coupling type is 1/3 Bayonet, and it is a square flange receptacle with a backnut.
Yes. It is MIL-DTL-26482 SI qualified and designed for demanding environments. Cadmium plating and aluminum shell provide corrosion resistance, while REACH compliance supports regulatory requirements in aerospace and defense programs.
This receptacle mates with Souriau 851-series plugs and other 32-contact, 1/3 bayonet interfaces in the same family. The N orientation and backnut-backshell arrangement simplify panel mounting and wiring harness integration in space-constrained assemblies.
The product carries MIL-DTL-26482 SI qualification and REACH environmental compliance. The cadmium plating and aluminum shell are standard features, and the connector is delivered with a ready-to-mate configuration for streamlined qualification testing.
