Feature → Business Impact → Application: The 85100E1626SX50 uses a 26-contact, high-density layout within a compact 16-shell size, enabling more connections per panel without increasing enclosure footprint and reducing wiring complexity in avionics and automated control panels. This translates to lower harness weight and improved reliability in space-constrained assemblies. Feature → Business Impact → Application: Cadmium plating on an aluminium shell provides corrosion protection and durability in demanding environments, extending service intervals and lowering maintenance costs for outdoor equipment and mobile platforms. Feature → Business Impact → Application: The aluminium shell reduces overall weight while maintaining strength, benefiting aerospace and automotive applications where weight budgets are critical and installation times matter. Feature → Business Impact → Application: 1/3 bayonet coupling allows fast mating and unmating during field servicing, minimizing downtime in production lines and on aircraft carriers or heavy industrial sites. Feature → Business Impact → Application: Backnut backshell and square flange receptacle construction deliver secure, vibration-resistant mounting, improving signal integrity in harsh environments and enabling easier installation in retrofit projects. Feature → Business Impact → Application: Solder Cup contacts provide robust terminations for harnesses and printed circuit assemblies, improving vibration resistance and simplifying assembly in rugged equipment. Feature → Business Impact → Application: Delivered with connector simplifies procurement and reduces assembly steps, accelerating system integration in panels, cabinets, and remote equipment installations.

FAQs
The 85100E1626SX50 is a square flange receptacle with backnut and 26 solder-cup contacts designed for the 851 series. For mating, use the corresponding Souriau 851-series plug and ensure the 1/3 bayonet coupling, orientation X, and backnut backshell are matched. This ensures proper alignment, seal integrity, and electrical continuity in MIL-DTL-26482 environments.
Operating from -40 °C to 125 °C, the 85100E1626SX50 is suitable for aerospace, defense, and rugged industrial applications where equipment experiences wide temperature swings and exposure to harsh conditions, ensuring reliable performance across the mission profile.
Yes. It is MIL-DTL-26482 SI qualified, features a cadmium-plated aluminium shell for corrosion resistance, and uses a 26-contact, 1/3 bayonet coupling design with a square flange receptacle. These characteristics balance ruggedness, weight, and ease of installation, making it a solid choice for aerospace and heavy-industrial automation systems.
The connector is MIL-DTL-26482 SI qualified, offering MIL-spec performance and reliability. Environmental compliance is indicated by REACH considerations in the product data, and the cadmium plating is aligned with traditional MIL-spec practices. Always verify any end-customer regulatory requirements for specific programs.
Plan panel layout to accommodate the square flange and backnut backshell, verify correct orientation (X), and use the 1/3 bayonet coupling for quick mating. Terminate with solder cup contacts using proper strain relief, secure with the backnut, and reference the C06851A drawings for mating receptacle-to-plug alignment and torque guidelines to minimize rework.
