Eaton 85100AC1832PY50 Square Receptacle - MIL-DTL-26482 SI
Part Number: 85100AC1832PY50
Quick Summary
The Eaton 85100AC1832PY50 is a MIL-DTL-26482 SI qualified square-flange receptacle used in rugged avionics harnesses. Engineers often struggle with mating reliability, corrosion resistance, and space constraints in compact aircraft bays. Its MIL-DTL-26482 SI qualification, cadmium plating, and aluminium shell deliver robust performance across harsh environments. This fits 32-pin interconnects for complex harnessing while offering lightweight, compliant, and install-friendly advantages. In procurement scenarios, engineers value compatibility with standard Souriau 851 accessories and predictable supply channels. This connector's 32 contacts support dense signal, power, and control lines in a single housing, reducing assembly steps. The straight backshell and Y orientation simplify installation where space is at a premium, improving field reliability. With cadmium plating and aluminium construction, you benefit from reduced weight, corrosion protection, and easier handling in tight aircraft environments.

FAQs
The 85100AC1832PY50 belongs to the Souriau 851 series MIL-DTL-26482 SI qualified family and mates with compatible 85100AC1832PY50 counterparts designed for PCB or harness terminations. It uses a square flange receptacle with a straight adaptor and 1/3 bayonet coupling, featuring 32 solder cup male contacts in Y orientation.
This interconnect is rated for -40 °C to 125 °C, supporting operation in extreme environmental conditions typical of aerospace, defense, and industrial equipment.
Yes. It is MIL-DTL-26482 SI qualified, employs a aluminium shell with cadmium plating for corrosion resistance, and is designed for rugged avionics harnesses and other mission-critical assemblies.
The shell is aluminium (lightweight) with cadmium plating for protection against corrosion. The combination reduces weight while maintaining mechanical robustness, enabling longer service life in harsh environments without compromising performance.
Plan for the straight backshell adaptor with Y orientation to simplify routing in tight spaces. Use solder cup terminations for reliable joints, and ensure proper bayonet mating to achieve audible engagement and secure retention during vibration-rich operation.
