Eaton 85100AC1418SY50 Receptacle - MIL-DTL-26482
Part Number: 85100AC1418SY50
Quick Summary
85100AC1418SY50 is a MIL-DTL-26482 qualified square-flange receptacle designed for rugged, high-reliability electrical connections in aerospace, defense, and industrial automation. Engineers often struggle with corrosion, vibration-induced loosening, and difficult field maintenance; this connector addresses those challenges with cadmium plating, an aluminium shell, and a robust 18-contact layout. The MIL-DTL-26482 SI qualification and REACH compliance provide regulatory assurance for mission-critical programs, while the adaptor backshell and Y-oriented, straight receptacle design streamline installation in tight panels. By combining a proven interface with solder-cup contacts and a 1/3 bayonet coupling, it delivers reliable mating and faster field service. For manufacturers, the result is improved uptime and lower life-cycle costs across harsh environments.
