Eaton 85100E2234SY50 Receptacle - MIL-DTL-26482
Part Number: 85100E2234SY50
Quick Summary
The Eaton 85100E2234SY50 is a square flange receptacle designed for rugged MIL-DTL-26482 connections in aerospace and industrial systems. Engineers often struggle with alignment during mating and moisture ingress in backnut assemblies, which can drive rework and delays. This design carries MIL-DTL-26482 SI qualification and REACH compliance, delivering regulatory assurance for aerospace, defense, and demanding industrial equipment. By combining a high-density 34-contact layout, cadmium plating, and a backnut shell, it enables faster installs, lower maintenance, and improved field reliability. Manufacturers benefit from predictable performance, easier sourcing, and reduced downstream service iterations through standardized Souriau 851 series interfaces.

FAQs
The 85100E2234SY50 uses a square flange receptacle with a 1/3 Bayonet coupling and backnut, designed to mate with corresponding Souriau/SBC assemblies in MIL-DTL-26482 configurations. It delivers a robust, quick-connect interface suitable for high-density harness applications and ensures proper orientation with the Y configuration.
Yes. It features an aluminium shell with cadmium plating and operates from -40 °C to 125 °C, providing reliable performance in demanding environments such as aerospace, defense, and industrial installations. It is also REACH compliant, supporting regulatory requirements in many regions.
Plan for straight backshell orientation (Backnut) and Y orientation, and account for the 34-contact layout to ensure proper harness routing. The backnut mounting simplifies panel installation, while the solder cup contacts simplify wiring to PCB or harness terminations. Ensure compatibility with the mating connector and verify panel cutouts match the 40 mm square footprint.
The 1/3 Bayonet coupling enables rapid mating and unmating, reducing service time and downtime during field maintenance. This design supports many cycles without compromising contact integrity, making it ideal for aerospace and industrial equipment that require frequent servicing or quick replacement of modules.
Best for aerospace avionics, defense vehicle systems, and rugged industrial equipment where high contact density and reliable environmental resilience are critical. The 34-contact configuration, cadmium-plated aluminium shell, and MIL-DTL-26482 SI qualification make it suitable for demanding applications needing regulatory compliance and long-term field reliability.
