Eaton 85100E1811PZ50 Receptacle - MIL-DTL-26482 SI Qualified
Part Number: 85100E1811PZ50
Quick Summary
The Eaton 85100E1811PZ50 Receptacle is a MIL-DTL-26482 SI qualified square-flange connector for rugged aerospace and industrial use, designed to withstand vibration and field conditions. In vibration-prone environments, unreliable mating, moisture exposure, and corrosion risk slow projects, drive spare-parts costs, and reduce system confidence. This design leverages MIL-DTL-26482 SI qualification and cadmium-plated aluminium shell with a straight backnut, providing robust mating and long service life in -40 to 125 °C environments. With an 11-contact configuration, solder cup contacts, and a Z-oriented 1/3 bayonet coupling, it enables rapid field assembly, high-density wiring, and improved reliability while reducing assembly errors. This translates to lower maintenance, faster diagnostics, and higher uptime across critical applications.
