Eaton 85100A898SX50 Receptacle - MIL-DTL-26482 SI Qualified
Part Number: 85100A898SX50
Quick Summary
The Eaton Souriau 851 series MIL-DTL-26482 SI qualified receptacle provides rugged, high-density connectivity for aerospace, defense, and rugged industrial automation. Engineers often face space constraints, misalignment during mating, and exposure to vibration or moisture in harsh field environments. MIL-DTL-26482 SI qualification and REACH-compliant materials help mitigate regulatory risk while delivering proven reliability. An aluminium shell with cadmium plating offers durable protection at a lightweight weight, supporting mobile or space-constrained deployments. The 98-contact layout and 1/3 bayonet coupling enable scalable, fast-mating assemblies that reduce installation time and total cost of ownership. For procurement teams, this combination translates to predictable performance, easier integration, and long-term value across complex programs.

Feature → Business Impact → Application: The 98-contact configuration provides high-density signal and power capability in a single connector, enabling designers to consolidate wiring and reduce panel footprint. This translates to shorter harness runs, easier routing in compact enclosures, and lower manufacturing labor costs during assembly in aerospace and robotics applications. Feature → Business Impact → Application: Solder Cup contacts offer robust, soldered terminations with excellent vibration resistance, improving long-term reliability in equipment subjected to dynamic loads in defense and industrial automation environments. Feature → Business Impact → Application: 1/3 Bayonet coupling delivers fast, secure mating with repeatable alignment, reducing field maintenance time and minimizing downtime on aircraft, ground vehicles, and heavy machinery. Feature → Business Impact → Application: Cadmium plating on an aluminium shell provides corrosion protection without excessive weight, enhancing service life in coastal, humid, or outdoor installations while supporting weight-sensitive platforms. Feature → Business Impact → Application: Operating temperature range from -40 °C to 125 °C and REACH compliance ensure performance consistency across extreme climates and strict regulatory regimes, enabling global deployments in harsh environments. Feature → Business Impact → Application: Square flange receptacle with straight backshell and X orientation simplifies integration with existing Souriau backshell adapters, speeding up design wins and reducing engineering risk in complex assemblies.

FAQs
To install, align the 85100A898SX50 receptacle with the compatible Souriau backshell adapter, engage the 1/3 bayonet coupling, and complete the mating sequence with gentle rotational seating. Ensure the orientation is X as specified and verify solder cup terminations are clean and correctly terminated. Confirm environmental seals and mechanical fit before commission testing.
Key specs include a 98-contact layout in a compact square-flange form, solder cup contact type for robust terminations, and an aluminium shell with cadmium plating for durability. The connector supports operation from -40 °C to 125 °C and uses a straight backshell with 1/3 bayonet coupling for secure, vibration-resistant mating.
Yes. The 85100A898SX50 is MIL-DTL-26482 SI qualified, designed for high-reliability environments typical of aerospace and defense systems. It combines high contact density, rugged materials, and vibration-resistant mating with regulatory considerations such as REACH compliance, making it well-suited for mission-critical applications.
You should verify MIL-DTL-26482 SI qualification status and REACH compliance for materials. While the part carries MIL-DTL-26482 SI qualification, always confirm regional CE or IP ratings if required by your program, and ensure compatibility with your system’s environmental and safety standards.
The 85100A898SX50 delivers a compact, lightweight profile (11.3 g) with high-density 98 pins and quick mating, reducing harness complexity and installation time. Durable aluminium construction with cadmium plating extends service life in harsh environments, lowering routine maintenance and replacement costs over the equipment’s lifetime.
