Eaton 85100E2232SW50 Receptacle - MIL-DTL-26482 SI
Part Number: 85100E2232SX50
Quick Summary
The Eaton 85100E2232SW50 is a MIL-DTL-26482 SI qualified square flange receptacle designed for rugged aerospace wiring applications. Engineers often struggle with moisture ingress, mis-mating, and maintaining regulatory compliance in harsh environments. This solution carries MIL-DTL-26482 SI qualification, is REACH compliant, and is cadmium plated for corrosion resistance. With a backnut, square flange interface, and solder-cup contacts, it streamlines installation, boosts reliability, and reduces support costs in aerospace and industrial automation. The connector ships with 32 solder cup contacts and a 1/3 bayonet coupling for secure panel mating. This standardization across the 851 series reduces spare parts complexity and shortens procurement cycles.

FAQs
Yes. The 85100E2232SW50 is designed as a square flange receptacle with a backnut that aligns with Souriau 851 series mating interfaces. It uses a 1/3 bayonet coupling and W-oriented connector geometry to ensure consistent panel fit and secure mating. When replacing legacy parts, verify shell size, contact layout (32 positions), and mounting hole pattern to avoid misalignment during installation.
MIL-DTL-26482 SI qualification ensures reliable mechanical engagement and environmental performance under vibration, thermal cycling, and humidity. For aerospace and defense programs, this reduces risk during integration, supports traceability, and helps meet stringent program QA and qualification requirements. It also aligns with high-reliability interconnect standards used in critical systems.
Yes. The 85100E2232SW50 features aluminum shell construction with cadmium plating and a wide operating temperature range of -40 °C to 125 °C, making it suitable for harsh environments including salt spray exposure. REACH compliance further supports environmental stewardship while maintaining performance in aerospace and industrial applications.
The product is delivered as a receptacle with connector options, including delivery with connector in certain configurations. This reduces field assembly steps and ensures compatibility with Souriau 851 series components. When ordering, confirm whether the connector assembly is included to match your system design and maintenance plan.
The 32-contact solder-cup arrangement enables high-density connections without adding complexity, reducing harness volume and weight. MIL-DTL-26482 SI qualification lowers field repair costs and warranty claims, while cadmium plating and aluminum shell improve corrosion resistance. Overall, this translates to lower maintenance intervals, improved uptime, and a more predictable total cost of ownership in aerospace and rugged automation deployments.
