The 85100A1210PY50 features a square flange receptacle with a straight adaptor and a cadmium-plated aluminium shell, delivering robust mechanical retention and corrosion resistance in demanding environments. This translates to improved assembly integrity and reduced field failures in aerospace and industrial automation. Its 1/3 bayonet coupling provides quick, secure mating, accelerating installation and maintenance while minimizing tooling requirements. The male solder cup contacts simplify wiring and PCB termination, lowering assembly time and potential contact fatigue in high-cycle applications. With 10 contacts arranged in 14 cavities, the layout supports clean circuit routing in compact panels, while the Y orientation and delivered connector option streamline harness integration. Operating from -40 °C to 125 °C ensures reliable performance across extreme temperatures common in automation cabinets and aircraft systems. The aluminium shell keeps weight down for easier handling and installation in limited spaces, improving overall system efficiency and reducing lifecycle costs. Designed for compatibility with standard Souriau 851 series interfaces, it supports scalable configurations and faster supply chain responses in value-driven projects.

FAQs
To install, align the square flange with the panel cutout, fasten using proper screws, and insert the connector into the mating half ensuring the straight adaptor seats correctly. Use the 1/3 bayonet coupling for secure engagement and verify the Y orientation to match your harness routing. Terminate wires with the solder cups, then confirm mechanical and electrical continuity with a controlled test.
Check the 10 contacts across 14 cavities, 41 mm depth, 26.5 mm width, 26.5 mm height, and 18.4 g weight. Verify the aluminium shell, cadmium plating, -40 °C to 125 °C operating range, 1/3 bayonet coupling, and the square flange receptacle form. Confirm the Y orientation and that the delivered connector option is compatible with your harness.
Yes. The MIL-DTL-26482 SI qualification ensures military-grade reliability, while the square flange receptacle and aluminium shell provide rugged performance in vibration and temperature extremes. REACH compliance supports regulated markets, and the cadmium plating enhances corrosion resistance, making it well-suited for aerospace and demanding automation applications.
The product is REACH compliant, aligning with environmental regulations for European and global supply chains. The cadmium plating offers corrosion protection, and the single-piece aluminium shell reduces weight while maintaining strength. Always verify current regulatory guidance for your specific project and consider any regional restrictions on cadmium usage.
The combination of quick 1/3 bayonet mating, solder cup termination, and lightweight aluminium construction reduces installation time and field maintenance. Its wide operating temperature range minimizes thermal-related failures, while MIL-DTL-26482 SI qualification lowers risk during certification. These factors together can shorten project timelines and lower lifecycle costs through improved reliability and easier downstream replacements.
