The 85100A2024SX50 utilizes a 24-position square flange receptacle design to maximize wiring density while maintaining reliable mating. This feature delivers a clear business impact: higher harness capacity with fewer interconnects, simplifying installation in compact panels and reducing overall assembly time in production. In practice, engineers can realize cost savings through fewer components and faster routing of cables in complex equipment. The aluminium shell with cadmium plating provides a lightweight yet durable enclosure, improving thermal performance and corrosion resistance, which translates to longer service life and lower maintenance costs in harsh environments such as aerospace and heavy industry. The straight backshell adaptor and X-oriented contact layout offer straightforward panel mounting and cable routing, enabling quicker field refurbishment and easier integration with existing Souriau 851 series systems. The 1/3 bayonet coupling delivers secure, repeatable mating with fast release, minimizing downtime during servicing and testing. The solder cup contact system (24 contacts) ensures robust, solder-stable terminations, helping to reduce contact failure rates in vibration-prone applications. Operating from -40 °C to 125 °C, the connector is suited for extreme temperature environments, delivering predictable performance across lifecycle. Delivered with connector readiness and a 24-position layout allows immediate deployment into production lines, reducing design risk and facilitating compliance with tight project schedules. The design supports modularity across aerospace, defense, and industrial automation programs, enabling scalable integration as systems expand or reconfigure.
