FAQs
The 85100A2041S50 uses a straight backshell adaptor and 1/3 bayonet coupling, designed for compatibility with Souriau 851 series assemblies. It features a 41-contact count, N orientation, and delivered-with-connector packaging to simplify integration into existing Souriau-based systems.
MIL-DTL-26482 SI qualification ensures electrical and mechanical integrity under demanding conditions, including vibration, temperature cycling, and exposure to contaminants. For this receptacle, it means trusted mating retention, consistent contact performance, and long service life in aerospace, defense, and rugged industrial deployments.
Yes. With a aluminium shell, cadmium plating, -40 to 125 °C operating range, and a 41-contact array, the 85100A2041S50 is well-suited for aerospace subsystems and high-reliability industrial automation panels where density, durability, and compliant materials are critical.
The receptacle lists REACH as an environmental condition, and uses cadmium plating per the specified configuration. Users should verify their specific regulatory obligations, but the design supports REACH compliance in typical European and global industrial ecosystems.
Cadmium plating provides corrosion resistance and stable electrical contact over time, reducing maintenance intervals and replacement costs. Its robust MIL-DTL-26482 SI qualification also minimizes field failures, delivering a favorable total cost of ownership for programs with long service lives and frequent connector mating.
