FAQs
The 85100A83APW50 uses a square flange receptacle with a straight adaptor and W orientation, designed for tight panel layouts. It supports three solder cup contacts in an aluminium shell and features a 41 mm length with 21 mm width and height, enabling secure mating in compact control cabinets.
Key specs include MIL-DTL-26482 SI qualification, cadmium plating, aluminium shell, pin (Male) solder cup contacts, 3 contacts, 1/3 bayonet coupling, and a 41 mm length. The connector is designed as a straight-back receptacle with a square flange and W orientation for precise alignment.
Yes. It supports operating temperatures from -40 °C to 125 °C and has REACH environmental compliance. Cadmium plating provides corrosion resistance, while aluminium housing offers EMI shielding and lightweight strength suitable for aerospace and industrial use.
The 1/3 bayonet coupling enables quick, repeatable mating with reduced torque and misalignment risk. It improves installation speed in field conditions and provides secure retention under vibration and thermal cycling, contributing to lower maintenance intervals and higher overall system reliability.
The combination of robust materials, MIL-DTL-26482 qualification, and REACH compliance reduces maintenance downtime and replacement costs. Its lightweight aluminium shell and reliable solder cup contacts support easier field servicing, predictable performance over extended lifecycles, and favorable total cost of ownership for OEMs and system integrators.
