Eaton 85100AC2025PW50 Receptacle - MIL-DTL-26482 SI Qualified
Part Number: 85100AC2025PW50
Quick Summary
The Eaton 85100AC2025PW50 Receptacle is a MIL-DTL-26482 SI qualified square-flange connector used in aerospace, defense, and rugged industrial harnesses. Designers often confront limited environmental tolerance, difficult installation, and uncertain contact performance; this option addresses those challenges with a robust aluminum shell, cadmium plating, and a straight backshell adaptor for straightforward routing. It embodies MIL-DTL-26482 SI qualification and REACH compliance, delivering regulatory confidence, corrosion resistance, and long-term reliability. The combination of 25-cavity capability, compact dimensions, and a W orientation supports efficient panel integration while maintaining high-density interconnectivity in constrained spaces. This makes it well-suited for mission-critical systems where durability and maintainability matter most, across aerospace and industrial automation programs.

FAQs
The 85100AC2025PW50 uses a square flange Receptacle with a straight backshell adaptor and a 1/3 bayonet coupling. To install, align the backshell with the panel cutout, engage the bayonet lugs, and rotate to lock. Ensure the orientation is set to W for correct mating geometry and verify contact seating with solder-cup pins. Use appropriate torque on mounting screws per your harness spec to prevent movement under vibration.
This connector is a 25-position, 25-contact layout with pin (Male) contacts delivered loaded in solder-cup form. It features cadmium plating on an aluminum shell (shell size 20) and operates from -40 °C to 125 °C. It is MIL-DTL-26482 SI qualified and REACH compliant, designed to maintain performance under vibration and extreme temperatures in aerospace and industrial applications.
Yes. It is MIL-DTL-26482 SI qualified, with a square flange receptacle, 1/3 bayonet coupling, and a rugged aluminum shell with cadmium plating. Its environmental range (-40 to 125 °C), 25-pin density, and W orientation make it appropriate for aerospace, defense, and other high-reliability systems requiring secure, vibration-resistant interconnects.
The product is MIL-DTL-26482 SI qualified and REACH compliant. Cadmium plating provides corrosion resistance, while the aluminum shell supports lightweight durability. These certifications and features help ensure regulatory compliance and long-term reliability in regulated industries and challenging outdoor environments.
With solder-cup contacts loaded in a cadmium-plated aluminum shell, routine inspection should focus on contact seating, insulation integrity, and mating alignment. The MIL-DTL-26482 SI qualification indicates high durability under vibration and temperature cycling, reducing maintenance frequency. Periodic cleaning, torque verification on mounting hardware, and inspection after exposure to harsh environments help sustain performance and extend service life.
