Feature → Business Impact → Application: The 36-contact layout enables high-density signal routing with fewer interconnect points, reducing panel footprint and installation time in automation cabinets. This translates to lower harness complexity and faster commissioning in factory floors or aerospace ground support equipment. Feature → Business Impact → Application: Solder cup contact delivery in a socket (female) configuration provides reliable fault tolerance in vibration-prone environments, improving mean time between failures (MTBF) and overall system uptime in harsh industrial settings. Feature → Business Impact → Application: Cadmium plating on an aluminum shell delivers robust corrosion resistance while maintaining a lightweight profile, supporting extended service life in coastal, humid, or dirty environments common to heavy industry. Feature → Business Impact → Application: 1/3 bayonet coupling with a straight backshell and N orientation simplifies mating, reduces installation torque, and accelerates field servicing for maintenance teams in critical production lines. Feature → Business Impact → Application: Square flange receptacle geometry and 22 shell size ensure compatibility with existing Souriau 851 series mating hardware, enabling straightforward upgrades or replacements without reengineering enclosures or harnesses. Feature → Business Impact → Application: Operating temperature range from -40 °C to 125 °C provides reliability across extreme climate zones and equipment enclosures, supporting both aerospace and industrial automation deployments with predictable performance. Feature → Business Impact → Application: REACH compliance and cadmium-based finish help meet environmental and regulatory expectations, reducing compliance risk and enabling broader supply chain approvals in regulated markets.

FAQs
The 85100AC2236S50 uses a square receptacle with a straight backshell adaptor, 1/3 bayonet coupling, and N orientation. It supports 36 solder cup contacts and a 22 shell size, allowing straightforward mating with existing Souriau 851 series hardware and enclosure interfaces.
It features a socket (female) contact type with 36 contacts loaded for immediate use, cadmium plating on an aluminium shell (shell size 22), and dimensions of approximately 53 mm length, 40 mm height, and 40 mm width. Operating temperature ranges from -40 °C to 125 °C, and weight is about 65.3 g.
Yes. It is MIL-DTL-26482 SI qualified, cadmium-plated for corrosion resistance, and REACH compliant, ensuring reliable performance in harsh environments and alignment with environmental regulations.
The 1/3 bayonet coupling provides fast, secure mating with minimal torque, reducing assembly time and the risk of misalignment. This is particularly beneficial in field servicing and maintenance of aerospace and industrial automation systems.
The combination of high contact density (36 contacts), robust cadmium plating, and a durable aluminium shell reduces maintenance intervals, lowers spare part variety, and improves uptime in automation lines, delivering lower total cost of ownership over the system lifecycle.
