FAQs
The 85100A123PY50 is a square flange receptacle designed for MIL-DTL-26482 interfaces with a straight backshell adaptor. It ships with connector options, supports Y orientation, and uses 1/3 bayonet coupling for fast, secure mating. This makes it compatible with standard Souriau 851 series backplanes and other MIL-spec assemblies commonly found in aerospace and rugged automation panels.
Key specs include three solder cup male contacts, a 41 mm depth, 26.5 mm height and width, aluminium shell size 12, cadmium plating, and operating temperature range from -40 °C to 125 °C. The connector is delivered as loaded with contacts and is REACH-compliant, suitable for high-reliability applications in harsh environments.
Common applications are aerospace and defense interconnects, rugged industrial automation, and test rigs that require MIL-DTL-26482 SI qualification. The compact 3-contact configuration within a square flange provides reliable power and signal interfacing in confined spaces, while the straight adaptor and bayonet coupling streamline installation on control panels and rack systems.
This part is MIL-DTL-26482 SI qualified and REACH compliant, ensuring both military-grade interconnect performance and environmental responsibility. While it does not specify IP or CE ratings, it aligns with industry expectations for rugged, high-reliability connections in aerospace, defense, and heavy industry.
By offering standardized MIL-spec compatibility, corrosion-resistant cadmium plating, and a lightweight aluminium shell, the 85100A123PY50 reduces maintenance cycles and extends service life in challenging environments. The quick-mating 1/3 bayonet coupling minimizes downtime during assembly and field servicing, delivering lower total cost of ownership for programs with repeated interconnect needs.
