MIL-DTL-26482 SI qualification and cadmium plating deliver enhanced environmental resistance, reducing corrosion-related failures and service costs. In aerospace and harsh-assembly environments, this means longer service intervals and lower maintenance budgets, supporting mission-critical operations without compromising safety. The square flange receptacle with backnut simplifies mounting on rugged panels, aligning with standard MIL cutouts for quick field upgrades.34 contact sockets with solder cup terminations streamline cabling runs and improve signal integrity. This configuration supports clean, reliable terminations in control panels and power distribution assemblies, reducing wiring errors and installation time.1/3 bayonet coupling and straight backshell orientation enable faster mating and robust retention in compact enclosures. The orientation “N” helps with consistent harness routing and reduces misalignment during maintenance.Lightweight aluminum shell (shell size 22) keeps overall weight within practical limits for mobile or rack-mounted equipment, while providing rugged mechanical strength.Operating temperature range from -40 °C to 125 °C covers extreme environments, including unconditioned outdoor installations and high-temperature industrial processes.Delivered with connector option and 34 contacts, this receptacle offers plug-and-play compatibility with Eaton Souriau connectors, minimizing integration risk and accelerating deployment in automation projects.

FAQs
Yes. The 85100E2234S50 is a square flange receptacle designed for MIL-DTL-26482 panel cutouts and features a backnut mounting arrangement. It uses a 1/3 bayonet coupling, a N-oriented interface, and 34 solder cup contacts, delivering a secure, field-installable connection that aligns with standard Eaton Souriau mating connectors and existing harnesses.
The assembly uses solder cup contact terminations with socket (female) contacts pre-loaded in the receptacle. The 34 contact cavities support reliable, vibration-resistant terminations ideal for control panels, power distribution, and rugged automation cabling. Terminations are suitable for robust field assemblies and reduce wiring complexity during installation.
This MIL-DTL-26482 SI qualified receptacle is ideal for aerospace, defense, and harsh industrial automation environments. With cadmium plating for corrosion resistance, an aluminum shell, and a wide operating temperature range, it excels in outdoor installations, salt-air coastal facilities, and unconditioned facilities where reliability and maintainability are critical.
Key standards include MIL-DTL-26482 qualification with SI (solder-interconnection) compliance. Environmental considerations include REACH compliance, cadmium plating for corrosion protection, and an operating temperature span of -40 °C to 125 °C, ensuring performance in extreme conditions common to aerospace and rugged industrial settings.
The square flange backnut design plus 1/3 bayonet coupling reduces installation time and field adjustments. With 34 solder cup contacts and pre-loaded sockets, technicians experience fewer wiring errors and quicker harness routing. The robust aluminum shell and wide temperature range extend service intervals, lowering maintenance frequency and total cost of ownership over time.
