Feature → Business Impact → Application: 12 solder cup contacts in a socket (female) arrangement delivers secure, low-impedance terminations with strong vibration resistance, reducing maintenance cycles and risk of intermittent connections in harsh environments. This translates to improved equipment uptime and lower field-service costs in industrial automation and mobile applications where reliability matters. Feature → Business Impact → Application: 1/3 bayonet coupling paired with a straight backshell adaptor enables quick mating/demating and straightforward installation in confined spaces, accelerating assembly and reducing torque-related damage during connector engagement. This is ideal for midline assembly lines and aerospace harness routing where time-to-install matters. Feature → Business Impact → Application: Cadmium plating on an aluminium shell provides robust corrosion resistance without sacrificing weight, supporting stable operation across -40 °C to 125 °C and in REACH-compliant environments. This supports long service life in outdoor and rugged indoor settings, including harsh industrial floors and transport systems. Feature → Business Impact → Application: Square flange receptacle, 12-position layout (Shell size 14) with a straight orientation (W) and loaded contacts ensures predictable harness routing and compatibility with standard Souriau 851 accessories, reducing design iterations and inventory complexity. This is crucial for program managers delivering high-reliability subsystems on tight schedules. Feature → Business Impact → Application: Delivered with connector and compatibility with solder cup contacts makes it straightforward to integrate into existing repairable assemblies, enabling rapid replacement and minimizing downtime in maintenance crews. This is especially valuable for defense and heavy-industrial automation where spare parts must be quickly swapped.

FAQs
The 85100A1412SW50 uses a square flange receptacle with a straight backshell and 1/3 bayonet coupling. It ships with the connector and features a W orientation, loaded contacts, and socket female solder cups. Ensure your panel cutout matches the flat-face square flange, and use compatible Souriau backshell accessories to maintain IP and vibration performance in rugged applications.
This part is a 12-contact receptacle with solder cup contacts, aluminium shell size 14, cadmium plating, and a straight backshell. It supports a -40 °C to 125 °C operating range, REACH environmental compliance, and MIL-DTL-26482 SI qualification, making it suitable for high-reliability military and industrial environments.
Yes. The MIL-DTL-26482 SI qualification, aluminium shell, and robust cadmium plating provide corrosion resistance and mechanical integrity for aerospace and defense, while the 12-contact configuration and quick-mating bayonet coupling suit demanding industrial automation harnesses and field service scenarios.
The connector is MIL-DTL-26482 SI qualified and REACH compliant, reflecting military-grade electrical performance with environmental responsibility. When selecting for a program, verify any additional program-specific requirements such as CE marking or IP ratings in your end-use case, as these are not explicitly listed in the base data.
The 85100A1412SW50’s solder cup contacts, 1/3 bayonet coupling, and lightweight aluminium shell reduce installation time and vibration-related failures, lowering maintenance costs and downtime. Its durable cadmium plating and wide temperature range improve service life in harsh environments, delivering better total cost of ownership for mission-critical systems.
