Eaton 85100A2236SX50 Receptacle - MIL-DTL-26482 SI Qualified
Part Number: 85100A2236SX50
Quick Summary
Eaton 85100A2236SX50 is a MIL-DTL-26482 SI qualified square flange receptacle for rugged aerospace and industrial cabling. Design engineers often struggle with maintaining mating integrity in vibration, temperature cycling, and harsh environments. This connector delivers MIL-DTL-26482 SI qualification, cadmium plating for corrosion resistance, and an aluminium shell that adds mechanical strength. Its 36-position layout, 1/3 bayonet coupling, and socket-only solder cup contacts enable reliable terminations even in tight spaces. By combining high-density performance with proven standards, it supports scalable cable harnessing, faster field assembly, and regulatory compliance across defense, aerospace, and automation applications. For procurement teams, the solution simplifies stocking by aligning with Souriau 851 series ecosystems and common backshell configurations.

MIL-DTL-26482 SI qualification paired with cadmium plating delivers corrosion resistance and proven interoperability. The business impact is longer service intervals, lower maintenance costs, and fewer field failures in aggressive environments. This feature is ideal for aerospace harnesses and industrial installations where connectors must perform under vibration and wide temperature ranges. High-density 36-contact layout with socket (female) solder cup contacts and a 1/3 bayonet coupling enables reliable terminations and quick mating. The application benefit is reduced assembly time and improved electrical performance in dense panels, with easier traceability for QA checks in defense and automation projects. Backshell adaptor and straight backshell orientation simplify panel mounting and routing. The business impact is fewer installation errors, cleaner harness routing, and compatibility with standard Souriau backshell kits across the 851 series. Aluminium shell size 22 with cadmium plating provides robust mechanical strength without a heavy footprint. This supports compact, lightweight assemblies in aircraft, mobile equipment, and robotics, while maintaining environmental protection in temperature extremes. Operating range -40 to 125 °C and 54 g weight make the part suitable for harsh environments where reliability matters most. Designed for easy integration, the delivered-with-connector option reduces extra purchases and ensures quick upgrade paths for legacy systems.

FAQs
The 85100A2236SX50 is designed to work with Souriau 851 series backshells and standard square flange panels. It ships with a straight backshell orientation (X) and supports a 1/3 bayonet coupling for fast, secure mating. It is ideal for high-density harnesses in aerospace, defense, and automation projects, simplifying integration with existing Souriau components.
This receptacle provides 36 solder cup contacts within a 36-position layout, aluminium shell size 22, cadmium plating, and a operating temperature range of -40 °C to 125 °C. The backplane orientation is straight, with 1/3 bayonet coupling for vibration resistance. It is delivered as a loaded receptacle with socket contacts to ensure quick field terminations.
Yes. It carries MIL-DTL-26482 SI qualification, a standard widely used in aerospace and defense. The aluminium shell, cadmium plating for corrosion resistance, and high-density 36-contact configuration make it suitable for avionics harnesses and other aerospace assemblies requiring reliable, vibration-tolerant connections.
The connector is MIL-DTL-26482 SI qualified and compatible with REACH environmental considerations. The cadmium plating provides corrosion protection, and the aluminium shell delivers structural integrity, ensuring compliance with industry expectations for rugged, mission-critical systems.
With 1/3 bayonet coupling and a 36-contact layout, mating and disassembly are faster than threaded alternatives, which reduces installation time and downtime. The high-density design minimizes harness complexity, lowers inventory diversity, and supports longer service life through improved vibration resistance and corrosion protection, delivering measurable maintenance and lifecycle cost savings.
