Feature → Business Impact → Application: The 85100AC1098S50 is a square flange receptacle with a straight adaptor and 1/3 bayonet coupling, delivering a compact, secure connection even in cramped installations. The fast mating provided by the bayonet design reduces installation time and minimizes the risk of misalignment, which is critical in high-vibration environments such as automated lines and mobile machinery. This configuration is ideal for aerospace panels and rugged industrial controls where space is premium and reliability is non-negotiable. Feature → Business Impact → Application: Cadmium plating paired with an aluminium shell offers excellent corrosion resistance while keeping weight low, translating to longer service intervals and lower lifecycle costs in field deployments. This construction is particularly beneficial for outdoor or marine-adjacent equipment where environmental exposure can accelerate wear. Feature → Business Impact → Application: Six solder cup contacts deliver robust electrical performance with tight signal integrity, supporting reliable data and power transmission across demanding automation networks. This arrangement simplifies harnessing and termination in confined spaces, making it well-suited for compact control cabinets and avionics-like panels.Feature → Business Impact → Application: The backshell adaptor option and straight orientation enable streamlined cable routing and easier field servicing, which reduces downtime during inspections and upgrades in production lines or mobile platforms. The compatibility with the Souriau 851 series ecosystem ensures a broad range of accessories and mating interfaces, helping OEMs standardize components across platforms. Feature → Business Impact → Application: Operating from -40 °C to 125 °C and cadmium-plated aluminium construction provide resilience against wide temperature swings and harsh environments, supporting uninterrupted operation in extreme climates and high-vibration applications such as off-road machinery, energy equipment, and aerospace ground support equipment. Feature → Business Impact → Application: Compact dimensions—48 mm length, 24.2 mm width and height, 16.2 g weight—combine lightweight, space-saving design with rugged performance, enabling more efficient panel layouts and reduced shipping costs for large-scale deployments in automation and control systems.
