FAQs
The 85100E2236SX50 is part of the Souriau 851 family and uses a 1/3 Bayonet coupling with a square flange receptacle. It shares the same backnut backshell approach and cadmium-plated aluminium shell, enabling straightforward integration with existing 851-series harnesses and mating interfaces while preserving mechanical and electrical consistency across modules.
To ensure reliable sealing and fast mating, align the 36-contact receptacle with the mating plug using the 1/3 Bayonet coupling, tighten the backnut to seal against environmental ingress, and verify the backshell is correctly oriented (X). Use cadmium-plated contacts and aluminium housing to optimize corrosion resistance and thermal performance in rugged environments.
Yes. The 85100E2236SX50 is MIL-DTL-26482 SI qualified, designed for demanding aerospace applications. It operates from -40 °C to 125 °C and is REACH compliant, delivering reliable performance under vibration, thermal cycling, and ambient contaminants typical of aerospace and defense systems.
Key specs include 36 solder cup contacts within a 36-position layout, a square flange receptacle with backnut, aluminium shell size 22, and 34.5 mm length. It uses cadmium plating, with a straight backshell and 1/3 Bayonet coupling, delivering robust electrical performance and straightforward field maintenance.
The 85100E2236SX50 streamlines sourcing by remaining compatible with the Souriau 851 ecosystem, reduces installation time with quick-mating 1/3 Bayonet coupling, and lowers maintenance costs through durable cadmium-plated aluminium construction and reliable REACH-compliant performance. In high-mix production environments, this translates to less downtime and faster spare-part substitution.
