Eaton 85100AC1811S50 Receptacle - MIL-DTL-26482 SI
Part Number: 85100AC1811S50
Quick Summary
Eaton 85100AC1811S50 Receptacle is a MIL-DTL-26482 SI qualified square-flange interconnect for rugged aerospace and industrial applications. In challenging environments, field failures often stem from corrosion, contact looseness, or incompatible backshells; this receptacle addresses those by cadmium plating, a robust aluminium shell, and a delivered adaptor backshell. It complies with MIL-DTL-26482 SI and REACH, providing regulatory alignment and long service life under wide temperature swings. For system integrators and procurement teams, the 11-contact layout, solder cup contacts, and straight orientation simplify panel installation, inventory management, and maintenance across mixed fleets.
