Eaton 85100E2234SW50 Receptacle - MIL-DTL-26482 SI qualified
Part Number: 85100E2234SW50
Quick Summary
Eaton Souriau 851 series MIL-DTL-26482 SI qualified receptacle enables rugged, MIL-spec connections for aerospace and harsh-industrial environments. Engineers confront mating accuracy, backnut retention, and corrosion risk in vibration-heavy applications, and unreliable interfaces can drive field failures and maintenance costs. MIL-DTL-26482 SI qualification delivers proven performance in shock, vibration, and thermal cycling, while REACH-compliant materials help meet global environmental standards. The aluminium shell with cadmium plating provides a lightweight yet durable enclosure, and the square flange receptacle with a backnut backshell ensures secure, repeatable mating. This 34-position, 1/3 Bayonet connector supports critical automation panels and high-density wiring, delivering reliable performance across the operating range from -40 to 125 °C in demanding environments.

FAQs
Yes. The 85100E2234SW50 is designed around the MIL-DTL-26482 SI qualified family and shares common interfacial geometry with compatible Souriau 851 series receptacles. It integrates a square flange receptacle footprint, backnut backshell, and 34-contact layout to preserve mating reliability when mixed within a system that uses the same series and coupling standard.
Install on a 40 mm by 40 mm panel cutout with proper mounting hardware to secure the square flange. Use the backnut to secure the backshell and provide strain relief. Ensure solder cup contacts are aligned with harness or PCB terminations and verify temperature suitability from -40 °C to 125 °C during assembly and testing.
Ideal for aerospace, defense, and rugged industrial automation panels where high-density wiring, vibration resistance, and MIL-spec reliability are critical. The 34-contact configuration supports complex signal and power distribution needed in control modules, avionics racks, and heavy equipment automation.
The connector carries MIL-DTL-26482 SI qualification for MIL-spec reliability and REACH-compliant materials where applicable. It features cadmium plating and aluminium shell design, balancing corrosion resistance with weight, while meeting stringent environmental and performance requirements typical in aerospace and defense programs.
Plan for vibration and thermal cycling as part of routine life-cycle testing. The 1/3 Bayonet coupling aids mating integrity under motion, and the backnut/backshell arrangement reduces seal leakage and remating risk. With 34 contacts in a compact footprint, ensure harness routing minimizes EMI/EMC interference and inspect solder joints during routine maintenance to sustain reliability.
