Cadmium plating and an aluminium shell provide corrosion resistance and reduced weight, improving longevity in outdoor equipment and military installations. This translates into lower maintenance costs and longer service intervals, particularly in harsh environments, where reliable connectivity directly impacts uptime and overall system performance. The five solder-cup contacts in a 5-position layout enable straightforward field assembly and robust signal integrity, while the 1/3 bayonet coupling ensures secure mating with minimal torque, simplifying installation in confined spaces. The Y orientation of the connector simplifies cable routing and panel design, reducing wiring errors and easing future reconfigurations. With a 48 mm depth and 28.9 mm width/height, the compact square flange receptacle fits tight control panels without compromising contact density. Its cadmium finish and aluminium shell support wide operating temperatures from -40 °C to 125 °C, expanding use cases across aerospace, defense, and industrial automation. Delivered with connector and loaded contacts, it minimizes preparation time and accelerates deployment in production lines.

FAQs
The 85100AC145PY50 uses a 1/3 bayonet coupling with a straight backshell and a square flange receptacle design. It carries five solder-cup male contacts in a 5-position layout, oriented with a Y connector alignment. Delivered as a connected assembly, it is compatible with the Souriau 851 series ecosystem, enabling straightforward pairing with corresponding receptacles and backshells for reliable, repeatable mating in tight panel spaces.
This receptacle features a depth of 48 mm, a width of 28.9 mm, and a height of 28.9 mm, with a shell size of 14. The device weighs 25.2 g and uses an aluminium shell with cadmium plating. These compact dimensions and moderate weight support dense panel layouts and ease of integration into demanding equipment housings.
The connector is rated for operation from -40 °C up to 125 °C, making it suitable for aerospace, defense, and industrial automation environments with wide thermal cycling. It is REACH compliant, which helps ensure environment-friendly manufacturing and usage. The cadmium plating additionally provides corrosion resistance in challenging field conditions, extending service life in outdoor or harsh installations.
The Eaton Souriau 85100AC145PY50 is MIL-DTL-26482 SI qualified, indicating stringent military/industrial interface standards. It also meets REACH environmental requirements, supporting compliance from design through field deployment. While not listed with IP ratings or CE marks in the provided data, the MIL-DTL-26482 qualification and REACH compliance are core regulatory assurances for rugged, mission-critical applications.
Plan for a straight backshell and square flange panel cut-out to accommodate the 28.9 mm by 28.9 mm profile with a 48 mm depth. Use the 1/3 bayonet coupling for fast, secure mating, and ensure solder-cup contacts are properly heated-soldered for repeatable connections. Since the unit ships loaded with contacts and is delivered with the connector, installation time and field rework are minimized, improving uptime and total cost of ownership.
