FAQs
This receptacle mounts via a square flange with a backnut backshell, supporting straightforward alignment and secure mating. Delivered with connector, the 36-contact array uses solder cup contacts and a Y orientation for precise wiring. Use the 1/3 bayonet coupling to achieve quick, vibration-resistant engagement in rugged environments.
Key specs include 36 contacts in a square flange receptacle with a straight backnut, aluminium shell size 22, cadmium plating, and solder cup contacts. It features 1/3 bayonet coupling, 34.5 mm depth, 40x40 mm footprint, weight about 50 g, and operates from -40 °C to 125 °C, meeting MIL-DTL-26482 SI qualification.
Yes. It is MIL-DTL-26482 SI qualified and built for demanding environments. The aluminium shell, backnut, and corrosion-resistant cadmium plating contribute to durability, while the operating temperature range supports extreme aerospace and defense applications. It also aligns with REACH environmental standards for responsible, compliant usage.
Plan for periodic inspection of the 36 solder cup contacts and mating surfaces to prevent corrosion or wear. The cadmium plating offers corrosion resistance, but surface cleanliness and proper mating alignment are essential to maintain signal integrity. Ensure proper torque on mounting hardware and use compatible mating connectors within the Souriau 851 family when expanding I/O.
The 85100E2236PY50 provides high contact density (36 circuits) in a rugged, MIL-grade package, reducing the number of connectors required and associated assembly time. Its durable aluminium housing and wide operating temperature range lower replacement and maintenance costs, while compatibility with Souriau 851 series simplifies inventory, spares, and future upgrades.
