Feature → Business Impact → Application: The 85100E106S50 employs a square flange receptacle with a backnut, enabling a secure, vibration-resistant fit that reduces field rework and equipment downtime. This translates into lower maintenance costs and higher system availability in aerospace, defense, and industrial automation environments. Application: installed in rugged enclosures where backnut assemblies are preferred and space constraints demand a compact 32.7 mm length and 24.2 mm width. Feature → Business Impact → Application: Cadmium plating on a lightweight aluminium shell delivers corrosion resistance and weight efficiency, improving service intervals and enabling longer mission-ready intervals in aircraft, ships, and outdoor industrial installations. Application: environments with exposure to moisture and salt spray in offshore or aerostructure facilities. Feature → Business Impact → Application: 1/3 bayonet coupling and 6-position layout offer quick, positive mating and re-mating cycles, shortening assembly time on production lines and in field retrofits. Application: harness assemblies requiring fast, tool-free connections. Feature → Business Impact → Application: Solder Cup contact delivery ensures reliable electrical connections and compatibility with standard PCB and harness termination methods, reducing assembly variability and supplier complexity. Application: precision instrumentation and control panels where soldered terminations are preferred. Feature → Business Impact → Application: Cadmium plating and an aluminium shell provide a good balance of durability and conductivity, enabling reliable shielding and long-term performance under high-temperature conditions. Application: high-temperature or temperature cycling environments such as engine compartments or industrial ovens. Feature → Business Impact → Application: Operating range -40 to 125 °C supports wide temperature resilience, reducing the need for alternative parts in mixed-temperature environments. Application: defense and aerospace equipment that experiences severe thermal swings. Feature → Business Impact → Application: Delivered with connector option simplifies procurement and reduces integration risk by ensuring plug-and-play compatibility with existing Souriau-based systems. Application: system upgrades or new builds that follow the 851 series ecosystem.

FAQs
Installation begins with aligning the 1/3 bayonet coupling and inserting the socket contacts into the corresponding mate. Tighten the backnut to secure the flange, ensuring the orientation remains N as specified. Verify solder cup terminations are clean and seated, then perform a functional test to confirm continuity and shielding performance. The connector is delivered with the connector, simplifying integration into existing Souriau-based systems.
Yes. The 85100E106S50 is specifically described as MIL-DTL-26482 SI qualified, designed to mate with compatible 851 series components. It features six contacts in a 6-cavity arrangement and uses solder cup contacts for reliable terminations. Compatibility is enhanced by the backnut mounting, straight backshell, and N orientation, which align with standard Souriau/Soulé configurations.
The 85100E106S50 supports a broad operating spectrum from -40 °C to 125 °C, enabling reliable performance across extreme environmental conditions. This makes it suitable for aerospace, defense platforms, and heavy industrial equipment that experience substantial thermal cycling.
The shell is aluminium with cadmium plating, providing a balance of light weight, corrosion resistance, and electrical performance. This combination supports robust shielding and longevity in challenging environments, while maintaining compatibility with standard Souriau 851 series accessories and tools.
Ideal for aerospace and defense equipment, as well as rugged industrial control panels, where a compact, square flange receptacle with six solder cup contacts, backnut mounting, and 1/3 bayonet coupling is advantageous. Its REACH compliance and robust construction support reliable field service and lifecycle management in mission-critical systems.
