Eaton 85100A123S50 MIL-DTL-26482 SI Qualified
Part Number: 85100A123S50
Quick Summary
Eaton Souriau 851 series MIL-DTL-26482 SI qualified connectors provide robust square flange receptacles for harsh environments. Engineers struggle with mating reliability and corrosion protection in compact, lightweight assemblies. MIL-DTL-26482 SI qualification and REACH compliance support stringent aerospace, defense, and industrial applications. By delivering a cadmium-plated aluminium shell with solder-cup contacts, it improves reliability and assembly speed. In practice, you gain consistent performance across -40 to 125 C and space-saving layouts for automation harnesses. The compact backshell adaptor and straight configuration simplify installation and cable routing. This makes field replacements faster and reduces training time for technicians. It also supports easy inspection and preventive maintenance programs.

FAQs
When integrating the 85100A123S50, plan for a square flange receptacle with a straight backshell adaptor and 1/3 bayonet coupling to ensure quick mating. Use the N orientation to align contacts and route cables along the 41 mm length while accommodating the 26.5 mm width in compact panels. The solder cup contacts require proper tinning and flux application for reliable, vibration-resistant joints.
The connector is MIL-DTL-26482 SI qualified and REACH compliant, designed for -40 to 125 °C operation, with a cadmium-plated aluminium shell and solder cup contacts. With 3 electrical contacts and an 8-cavity footprint, it provides stable electrical performance in demanding environments. Built to withstand harsh exposure, it minimizes corrosion risks and maintains signal integrity under vibration and temperature cycling.
Yes. The 85100A123S50 lives in the Souriau 851 series, a family recognized for MIL-spec compatibility and robust mechanical design. The aluminum shell, cadmium plating, and MIL-DTL-26482 SI qualification make it well-suited for aerospace and defense interconnects, where reliability, resistance to corrosion, and predictable performance under thermal cycling are essential.
This connector meets MIL-DTL-26482 SI qualification and REACH environmental compliance. Verification can be done via Eaton/Souriau technical data sheets, manufacturer certification documents, or qualified supplier listings that document MIL-spec conformance and REACH compliance. For critical programs, request a certificate of conformity and test reports showing environmental and mechanical test results.
ROI comes from reduced maintenance, faster installation, and longer service life. The cadmium-plated aluminium shell offers superior corrosion resistance, the solder-cup contacts provide durable, field-robust joints, and the 1/3 bayonet coupling speeds mating. These factors translate to lower downtime, fewer field repairs, and a more predictable bill of materials in high-reliability automation and aerospace programs.
