Feature is 36 contact solder cup layout, providing a dense, high-current capable connection that supports complex harnesses and reduces interconnect count for the same machine footprint. Business impact is improved wiring density and lower assembly time, enabling faster system integration and reduced panel space. This is particularly valuable in aerospace and industrial equipment where space is at a premium and reliability is non-negotiable. Application: suitable for square flange receptacle implementations with 36 cavities, enabling a compact yet powerful interface. Feature cadmium plating and aluminium shell deliver corrosion resistance and light weight, reducing maintenance cycles and total cost of ownership. Business impact is lower lifecycle costs and extended service life in aggressive environments; application spans control panels, deployable systems, and field deployable modules. Feature 1/3 bayonet coupling provides quick, secure mating with repeatable alignment, minimizing technician time during assembly and reconfiguration. Business impact is faster builds and easier field servicing; application includes rapid swaps in production lines and on-aircraft maintenance. Feature backshell adaptor compatibility simplifies integration with existing harnesses and cable assemblies, reducing custom machining and ensuring reliable shielding. Application: retrofit-ready for legacy systems, with consistent EMI/RFI performance. Feature delivered-with-connector option saves time and reduces risk by providing a ready-to-install assembly, lowering procurement complexity and improving supply chain predictability. Application: ideal for programs prioritizing turnkey readiness. Feature REACH compliance and MIL-DTL-26482 SI qualification address regulatory and standards-driven requirements, supporting risk management and customer audits. Business impact is smoother procurement cycles and greater trust in supply consistency; application spans defense, industrial automation, and high-reliability equipment.

FAQs
The 85100AC2236SW50 is a square flange receptacle with a straight backshell and a W orientation. It uses a 1/3 bayonet coupling for fast, reliable mating and comes delivered with the connector for streamlined installation. Its 36-contact layout supports dense wiring harnesses, while the aluminium shell and cadmium plating enhance durability in harsh environments.
This Eaton receptacle is rated for operation from -40 °C to 125 °C, providing reliable performance across extreme temperatures typical in aerospace and industrial equipment. The aluminium shell and cadmium plating contribute to corrosion resistance, making it suitable for exposed or harsh settings without compromising signal integrity.
Yes. The design supports REACH environmental requirements, aligning with modern regulatory expectations for materials and finishes. The MIL-DTL-26482 SI qualification further supports compliance with stringent industry standards and audit readiness, helping procurement and engineering teams minimize risk during vendor qualification.
The backshell adaptor enables direct compatibility with existing cable assemblies, reducing the need for custom harnesses or rework. This minimizes installation time, lowers labor costs, and improves EMI/RFI shielding continuity, which is critical in high-density systems and environments with strong electrical noise.
Aerospace, defense, and rugged industrial automation benefit most from this receptacle due to its 36-contact density, robust MIL-DTL-26482 SI qualification, and resistance to harsh temperatures. Its square flange design and delivered-with-connector option simplify integration into existing panels and assemblies, accelerating program timelines and improving reliability in demanding environments.
