Eaton 85100AC2234SZ50 Receptacle - MIL-DTL-26482
Part Number: 85100AC2234SZ50
Quick Summary
Eaton 85100AC2234SZ50 Receptacle is a MIL-DTL-26482 qualified connector for high-reliability aerospace and industrial applications. Engineers often grapple with mismatched backshells, corrosion-prone finishes, and difficult field assembly in tight enclosures. This design uses MIL-DTL-26482 SI qualification and REACH-compliant cadmium plating to balance rugged performance with regulatory alignment. The aluminium shell and 34-contact layout deliver robust signal and power paths, while the straight backshell and Z orientation simplify mating in limited spaces. For procurement and maintenance teams, that translates into lower lifecycle costs, easier stocking of a common 34-position interface, and faster, safer replacements in mission-critical systems.

FAQs
The 85100AC2234SZ50 is a MIL-DTL-26482 SI qualified square flange receptacle with 34 solder cup contacts, designed to mate with MIL-DTL-26482-series inserts and backshells. Its 1/3 Bayonet coupling and Z-oriented backshell simplify alignment and mating in constrained spaces, making it a reliable choice for high-density assemblies in aerospace and industrial equipment.
The 1/3 Bayonet coupling provides a positive, quick-mate action that reduces cycle time during assembly and field maintenance. Combined with the straight backshell and Z orientation, it improves alignment, decreases risk of mis-mating, and facilitates faster, safer replacements in tight compartments typical of avionics bays and industrial control panels.
Yes. The receptacle operates from -40 °C to 125 °C and uses a cadmium-plated aluminium shell for enhanced corrosion resistance. MIL-DTL-26482 SI qualification further ensures rugged interface integrity under vibration, thermal cycling, and environmental exposure common in aerospace, defense, and rugged industrial applications.
Cadmium plating provides corrosion protection but may be subject to regional regulatory restrictions. The product supports REACH compliance, aiding in restricted-substance management. Always verify any regional cadmium usage rules and ensure conformity with your project’s environmental and safety requirements.
The unit features a 53 mm length, 40 mm width, 40 mm height, and a 34-contact cavity array within a 22 shell size. With an aluminium shell and straight backshell, ensure clearance for mating, harness routing, and terminal access. The Z orientation and backshell adaptor simplify mounting in constrained enclosures and support lean, serviceable harness layouts.
