Feature: MIL-DTL-26482 SI qualification establishes traceable, military-grade interoperability and long-term compatibility. Business Impact: Reduces certification time for systems integrators and minimizes field failure risk across mission-critical platforms. Application: Suitable for aerospace control panels, defense electronics, and rugged industrial cabinets that demand certified performance. Feature: 36 contact positions in a compact 22 shell size with 1/3 bayonet coupling and solder cup contacts. Business Impact: Increases housing density and simplifies harness assembly, cutting wiring complexity and labor costs. Application: Ideal for high I/O in control panels and automation networks where space is at a premium. Feature: Cadmium plating with an aluminium shell provides corrosion resistance and lighter weight. Business Impact: Extends service life while reducing mounting stresses and energy use in dynamic environments. Application: Supports mobile equipment, maritime enclosures, and outdoor installations. Feature: Straight backshell adaptor and W orientation streamline panel mounting and mating alignment. Business Impact: Accelerates installation, ensures correct mating orientation, and minimizes rework. Application: Useful in fixed installations in aircraft racks and industrial enclosures requiring precise alignment. Feature: Delivered with connector and 1/3 bayonet coupling supports quick engagement and reliable retention. Business Impact: Reduces procurement steps, speeds deployment, and improves maintenance response times. Application: Works across the Souriau 851 family for scalable, repeatable system builds. Objection handling: Cadmium plating and environmental considerations are addressed by REACH compliance and documented handling guidelines, while the aluminium shell provides strength with reduced weight, supporting lifecycle cost reductions.

FAQs
The 85100A2236PW50 is a square flange receptacle in the MIL-DTL-26482 family, delivered as a complete connector unit with 36 solder-cup contacts. It maintains compatibility with MIL-DTL-26482 interfaces through its 1/3 bayonet coupling and standard Souriau 851-series geometry, enabling straightforward integration into existing assemblies and harnesses without custom adaptations.
This receptacle supports operation from -40 °C to 125 °C, suitable for extreme ambient conditions. It also carries REACH compliance, and uses an aluminium shell with cadmium plating for corrosion resistance, making it appropriate for outdoor, military, and industrial environments where reliability and regulatory compliance matter.
Yes. The 1/3 bayonet coupling provides fast engagement and secure retention, while the straight backshell adaptor and W orientation simplify mating alignment. Delivered as a connector-ready assembly, it minimizes field rework and reduces downtime during maintenance or upgrades.
The connector uses pin (male) contacts with solder cup termination, delivering 36 contacts across the 36 cavities. This arrangement supports straightforward hand-solder or automated soldering processes and is well-suited for board-to-wire or equipment-to-harness connections in dense I/O layouts.
The assembly features a 44 mm depth, 40 mm height, and 40 mm width, with a compact 22 shell size. It weighs 48 g, enabling lightweight interconnects in tight panel spaces and helping maintain overall system weight budgets for aerospace and mobile equipment.
