FAQs
The 85100AC83AS50 is a square flange receptacle designed for 3-contact configurations and a 1/3 bayonet coupling. It ships with a connector and is oriented for N-backshell alignment. It fits standard 851-series backshells and mating receptacles, simplifying panel integration and field servicing while maintaining alignment reliability in vibration-prone environments.
Key specs include 3 contacts in a 3-way cavity arrangement, 48 mm length, 21 mm width, 21 mm height, and a weight of 12.9 g. It uses cadmium plating on an aluminium shell, operates a temperature range from -40 °C to 125 °C, and features a 1/3 bayonet coupling with solder cup contacts for durable terminations.
Yes. It is MIL-DTL-26482 SI qualified and REACH compliant, providing safety integrity and environmental compliance. The aluminium shell, cadmium plating, and robust 1/3 bayonet coupling support vibration resistance and corrosion protection, which are critical in aerospace, military, and heavy industrial deployments.
The cadmium plating paired with an aluminium shell delivers corrosion resistance while keeping weight low, reducing downtime for maintenance and part replacements. The 1/3 bayonet coupling enables quick mating/demating, lowering maintenance time in field service. The solder cup contacts offer reliable, durable terminations that resist degradation under thermal cycling.
The product is delivered as a connector with a backshell adaptor option, and it is oriented for N configuration. This reduces the need for additional mounting hardware, simplifies assembly, and ensures a proper, repeatable seal and alignment in panel-mounted assemblies, particularly in contour-constrained or high-vibration environments.
