Eaton 85100AC145S50 Receptacle - MIL-DTL-26482 SI qualified
Part Number: 85100AC145S50
Quick Summary
The Eaton 85100AC145S50 receptacle enables MIL-DTL-26482 SI qualified power and signal connections in harsh environments. Engineers often struggle to choose connectors that withstand vibration, wide temperature swings, and regulatory scrutiny without complicating assembly. This product delivers MIL-DTL-26482 SI qualification and REACH compliance, paired with a cadmium-plated aluminium shell for long-term corrosion resistance. Its square flange receptacle design and 5-contact layout support compact, panel-mounted installations, while the straight backshell with adaptor option simplifies field wiring. With 1/3 bayonet coupling and socket (female) contacts, it offers secure mating in tight spaces. By standardizing on this Souriau 851 series part, teams reduce spare parts variety and accelerate sourcing across aerospace and industrial automation programs.
