FAQs
The 85100AC1210SZ50 is a square flange receptacle with a straight backshell adaptor and Z orientation. Use the 1/3 bayonet coupling for secure mating with a corresponding plug. Ensure the mating connector matches the 10-contact layout, and align the backshell adapter with your panel cutout to simplify harness routing and reduce installation steps.
This receptacle operates from -40 °C to 125 °C and uses solder cup contacts. It delivers a 10-contact, high-reliability connection with cadmium plating and an aluminium shell, optimized for vibration and thermal cycling common in aerospace and defense environments.
Yes. The MIL-DTL-26482 SI qualification, square flange receptacle design, 1/3 bayonet coupling, and Z orientation make it well-suited for aerospace and defense harnesses, as well as rugged industrial automation applications that demand reliable mating under harsh conditions.
The product carries MIL-DTL-26482 SI qualification and REACH environmental compliance. Cadmium plating is specified, which provides corrosion resistance, though manufacturers should consider alternative finishes where cadmium usage is restricted by local regulations.
Delivered with connector options and a straightforward straight backshell design reduce assembly steps and field labor. The rugged aluminium shell and 10-pin configuration enable longer service life with fewer outages, lowering maintenance costs and improving system uptime for OEMs and integrators.
