Feature → Business Impact → Application: The 85100E1626PY50 uses a square flange receptacle with a backnut and cadmium plating to provide a compact, mechanically secure interface that resists contamination in rugged environments. This combination reduces field assembly time and minimizes mating misalignment during panel installation, translating to faster deployments and lower rework on aircraft and industrial machines. It is well-suited for aerospace panels, control consoles, and mobile equipment where space is at a premium. Feature → Business Impact → Application: The 26-contact arrangement with a 1/3 bayonet coupling delivers quick, confident mating and strong vibration resistance, reducing intermittent electrical faults in dynamic environments. With solder cup contacts, field terminations become straightforward and repeatable, lowering crimping errors and improving signal integrity in robotics, machine tools, and factory automation panels. Feature → Business Impact → Application: Cadmium plating and an aluminium shell provide robust corrosion protection and weight savings, supporting longer service life in harsh environments while maintaining the 16-shell size for standardization. The compact 32.7 mm length and 31.3 mm width enable dense panel layouts and easier cable management in aircraft avionics bays and rugged industrial enclosures. Operating temperature range from -40 °C to 125 °C ensures performance in extreme conditions. Feature → Business Impact → Application: Solder Cup contact type and male pins enable secure, soldered terminations that resist loosening under vibration, improving long-term reliability. A 26-position layout supports rich electrical/topology options without increasing panel footprint, ideal for power and signal integration in automation cabinets, process control, and avionics interfaces. Feature → Business Impact → Application: Backnut backshell compatibility and the option to deliver with connector simplify installation and spare management, reducing assembly steps and inventory complexity. Straight backshell with Y orientation supports flexible routing and panel spacing, enabling rapid field assembly and consistent performance across Souriau 851-series ecosystems in defense, industrial, and transportation projects.

FAQs
Mounting begins with aligning the square flange receptacle to the panel cutout and threading the backnut over the panel sleeve. Tighten to spec to ensure a water-resistant, vibration-resistant seal. Use compatible Souriau 851-series backshell hardware for optimal routing and strain relief. Verify solder cup terminations are clean and noted for inspection.
The assembly provides 26 solder cup contacts in a 26-position layout, with a 1/3 bayonet coupling for secure mating. Cadmium plating on an aluminium shell yields corrosion resistance, while the operating range spans -40 °C to 125 °C, supporting performance in extreme environments common to aerospace and industrial applications.
Yes. The 85100E1626PY50 is designed for high-reliability avionics panels and heavy-duty automation enclosures, where space is constrained and environmental exposure is a concern. Its 26-contact configuration supports mixed power and signal needs, and the backnut backshell combination simplifies installation in demanding environments.
This receptacle is MIL-DTL-26482 SI qualified, with REACH compliance noted in the product family. Depending on your market, CE marking and IP ratings may be pursued by the OEM or end-user requirements. Plan for environmental and safety documentation, and verify site-specific regulatory expectations during design review.
The solder cup terminations offer robust, vibration-resistant joints that resist loosening over time, reducing field maintenance. The standard 26-position format simplifies spares and inventory, while the backnut/backshell compatibility minimizes assembly steps, contributing to lower total cost of ownership and faster mean time to repair (MTTR) in production environments.
