FAQs
The 85100A2025PY50 is a MIL-DTL-26482 SI qualified receptacle designed for high-density interconnects in both aerospace and industrial automation. It uses a straight backshell adaptor, 25 solder-cup contacts, and a Y-oriented male contact layout, making it compatible with Souriau 851-series panel assemblies and standard 1/3 bayonet mating interfaces.
With a 25-contact layout and a compact 44 mm depth, the connector maximizes signal density without increasing panel footprint. The 1/3 bayonet coupling enables rapid, repeatable mating, while solder-cup contacts ensure reliable field soldering. This combination reduces installation time and improves wiring reliability in control cabinets and robotics applications.
Yes. It operates from -40 °C to 125 °C and uses cadmium plating with an aluminium shell for enhanced mechanical robustness and corrosion resistance. Additionally, REACH compliance supports regulatory requirements in diverse markets, making it suitable for outdoor machines, offshore equipment, and other demanding industrial scenarios.
The straight backshell adaptor simplifies harness routing and panel cutouts, while the Y orientation defines connector positioning for consistent mating alignment. When integrating, ensure correct panel hole patterns for a 25-contact square flange receptacle, use the supplied connector with appropriate mating harnesses, and verify correct solder-cup contact orientation to maintain signal integrity.
Using MIL-DTL-26482 SI qualified connectors reduces field failures and maintenance costs due to proven reliability in demanding environments. The dense 25-contact layout, quick 1/3 bayonet mating, and absence of complex tooling translate to faster installation, lower labor costs, and longer service life for automation equipment, driving lower total cost of ownership over the system’s lifecycle.
