FAQs
The 85100A82S50 uses a square flange receptacle with a straight backshell adaptor and 1/3 bayonet coupling. Align the panel cutout to the 8-contact interface, insert, and twist to engage the bayonet locks. The assembly is delivered with connector, simplifying harness attachment and reducing installation time in panel-mount applications.
This connector features eight solder cup contacts in a single receptacle, with a product temperature range from -40 °C to 125 °C. The aluminium shell is cadmium plated for corrosion resistance, and the layout supports reliable power and signal distribution in demanding environments typical of aerospace and industrial applications.
Yes. The 85100A82S50 is MIL-DTL-26482 SI qualified for stringent aerospace and defense environments, designed to endure vibration and temperature extremes. Its aluminium shell, cadmium plating, and REACH considerations make it suitable for rugged industrial sites as well as aircraft and spacecraft electrical systems.
Key compliance attributes include MIL-DTL-26482 SI qualification and REACH environmental considerations. The combination of 85100A82S50’s cadmium plating and aluminium shell aligns with aerospace-grade practices, while the SI qualification provides confidence in mating integrity across lifecycle stages.
Benefits include reduced downtime from fast, tool-less mating via the 1/3 bayonet coupling, improved reliability with solder cup contacts, and long-term durability from aluminium housing and cadmium plating. These factors translate to lower maintenance costs, fewer field failures, and a shorter time-to-deploy cycle for critical systems.
