FAQs
To install, align the square flange with the panel cutout and secure it using the appropriate fasteners for the 12-shell size. Mate the 1/3 bayonet coupling with the mating plug, ensuring the connector orientation is set to N as specified. Verify solder cup connections are clean and seated, then test continuity and torque specifications per your assembly guidelines.
The assembly provides four contacts in a solder cup configuration, socket (female) contacts, and a 1/3 bayonet coupling for secure mating. It uses a cadmium-plated aluminium shell, operates across -40 °C to 125 °C, and fits a 41 mm length with 26.5 mm width/height in a size 12 shell. It is REACH compliant and delivered as a complete connector unit.
Yes. The 85100A124S50 is MIL-DTL-26482 SI qualified, a standard used in demanding aerospace and defense interconnects. Its square flange receptacle form factor, cadmium plating, and wide operating temperature range help it withstand vibration, temperature swings, and environmental exposure typical in aircraft and space hardware.
The product carries MIL-DTL-26482 SI qualification and REACH compliance, with cadmium plating on an aluminium shell.
