High-density 34-position solder-cup contacts enable compact harnessing in tight equipment bays. This feature reduces panel footprint and simplifies wire routing while preserving signal integrity, delivering a lower installation cost and easier serviceability in aircraft, defense, and industrial automation systems. Bayonet coupling provides fast, positive engagement with a single turn. The 1/3 bayonet design reduces mating time and misalignment risk during field wiring and equipment swaps, improving uptime in harsh environments such as aircraft cabins and rugged factories. Cadmium plating on an aluminium shell offers corrosion resistance and light weight, extending service life in challenging environments. The adaptor backshell and delivered connector option streamline installation and ensure consistent mating performance across assemblies. Operating temperature range from -40 °C to 125 °C supports extreme environments, while the 58.6 g weight and compact dimensions facilitate integration into compact systems. With 34 contacts and 34 cavities, the design supports reliable power and signal distribution in demanding applications. Compatibility and installation are enhanced by delivery with connector and a Y orientation, simplifying wiring harness integration and panel mounting. Industry objections about cost or availability are addressed with a proven mil-spec platform, long lifecycle, and readily available spares; the 85100AC2234PY50’s standardization within the MIL-DTL-26482 family reduces procurement risk and simplifies cross-compatibility across equipment.

FAQs
The 85100AC2234PY50 is a square flange receptacle from the Souriau 851 series and adheres to MIL-DTL-26482 with SI qualification, ensuring broad compatibility with other MIL-DTL-26482 plug and receptacle partners. It features 34 solder-cup male contacts and a 1/3 bayonet coupling, facilitating reliable mating with matching 34-position backshell assemblies and standard Souriau connectors in defense and aerospace harnesses.
Key specs include 34 contacts in a 34-cavity layout, pin (Male) contact type with solder cup ends, cadmium plating, aluminium shell, shell size 22, 53 mm length, 40 mm height and width, and a weight of 58.6 g. The backshell is adaptor-type with straight orientation, and the mating system uses a 1/3 bayonet coupling. Operating temperature ranges from -40 °C to 125 °C and it supports REACH compliance.
This receptacle is well-suited for aerospace, defense, and rugged industrial automation where high-density connections, vibration resistance, and reliable mating are critical. The square flange design enables compact panel mounting, while the bayonet coupling ensures quick, secure mating in field and on-assembly lines. Its cadmium-plated aluminium shell helps resistance to corrosive environments common in aircraft and heavy industry.
Plan for proper alignment during mating, leveraging the 1/3 bayonet coupling for rapid engagement. The straight backshell adaptor simplifies harness routing and mounting, and the 53 mm × 40 mm footprint supports compact integration. Ensure the 34-position cavity alignment matches the mating connector, and verify cadmium plating remains intact to maintain corrosion protection in service.
Yes, the 85100AC2234PY50 is specified with REACH environmental considerations, aligning with regulatory expectations for chemical substances and restricted materials in European markets. This compliance reduces regulatory risk during procurement and deployment in projects governed by REACH, and supports a smoother supply chain integration for defense, aerospace, and industrial automation programs.
