Eaton 85100AC1832SX50 Receptacle - MIL-DTL-26482 SI
Part Number: 85100AC1832SX50
Quick Summary
85100AC1832SX50 is a MIL-DTL-26482 SI qualified square flange receptacle for rugged aerospace and industrial harness applications. Engineers often struggle to source compact, high-reliability connectors that withstand extreme temps, vibration, and corrosion in demanding environments. It carries MIL-DTL-26482 SI qualification, supports REACH environmental compliance, and is designed for aerospace-grade reliability. This square flange receptacle uses cadmium plating and solder-cup contacts for fast, vibration-resistant installs, helping reduce lifecycle costs. With 32 contacts and a 1/3 bayonet coupling, it delivers secure mating in tight spaces. Its aluminium shell size 18 and cadmium finish balance lightweight construction with longevity in demanding environments. Designed for REACH-compliant assemblies, it supports durable performance under -40 to 125 °C.

FAQs
For seamless integration, verify the mating interface is a compatible square flange receptacle with a 1/3 bayonet coupling. Ensure the solder-cup contacts are correctly terminated to the harness wires, and that the X orientation aligns with the harness routing. Use the adaptor backshell to simplify cable management and minimize stress on the contact interfaces during vibration. Pre-mating checks with a go/no-go gauge help prevent misalignment and port damage during field assembly.
The 32-contact 32-cavity layout provides high-density signaling with a secure bayonet latch that maintains mating integrity under vibration. The 1/3 bayonet coupling offers quick, repeatable engagement while maintaining consistent contact pressure, reducing intermittent contacts. This combination delivers reliable signal integrity and power delivery in aircraft, military vehicles, and rugged industrial machinery where movement is common.
Yes. MIL-DTL-26482 SI qualification ensures performance under military-specified environments, including immersion, vibration, and temperature extremes. REACH compliance supports regulatory requirements for chemical substances. The aluminium shell, cadmium plating, and 1/3 bayonet coupling further enhance durability and ease of maintenance in aerospace and defense applications.
Regular visual inspection for corrosion or wear on the cadmium finish is advised, especially in harsh environments. Check contact seating and solder joints for signs of oxidation or loosening after thermal cycling. Use appropriate cleaning agents compatible with aluminium and cadmium plating, and perform periodic mating checks to ensure the 1/3 bayonet coupling remains secure and aligned.
Expected ROI includes reduced field failures due to MIL-DTL-26482 SI reliability, faster assembly from 1/3 bayonet mating, and longer service life from corrosion-resistant cadmium plating and aluminium shell. The 32-contact density enables compact harness designs, lowering panel space and weight. Overall, maintenance costs drop as field reworks and replacements become less frequent in vibration-intensive environments.
