FAQs
The 85100A147S50 uses a square flange receptacle with a straight backshell adaptor, designed for panel mounting with standard cutouts. Ensure a precise 41 mm depth and 28.9 mm width clearance, align the N-oriented connector, and use the delivered connector to simplify field assembly. Proper torque and bayonet engagement prevent misalignment.
The 1/3 bayonet coupling provides a positive, quick-connect mating that resists loosening under vibration and shocks. In aerospace and heavy equipment, this translates to stable contact pressure and reduced intermittent connections, enabling reliable signal transmission and easier maintenance during field servicing.
Yes, the 85100A147S50 is designed for aerospace-grade use, featuring MIL-DTL-26482 SI qualification and REACH compliance. The aluminium shell with cadmium plating offers corrosion resistance, while the 7-contact solder-cup arrangement supports robust harness connections in demanding environments.
Cadmium plating provides corrosion resistance, but cadmium usage is regulated in many regions. For long-term reliability, inspect mating interfaces for wear and ensure compliant handling and disposal practices. If cadmium-free alternatives are required, evaluate newer Souriau/SR options with equivalent performance.
The connector supports seven contacts in a 7-cavity arrangement with socket (female) solder cup contacts. It features a square flange receptacle, straight backshell adaptor, cadmium plating on aluminium shell size 14, and operating temperature from -40 to 125 °C. It is delivered with connector and supports N orientation for panel mounting.
