Feature → Business Impact → Application: The square flange receptacle with a straight adaptor and aluminium shell reduces mounting footprint and overall weight while maintaining structural integrity, enabling compact layouts in control panels and deployable machinery. This translates to cost savings in weight-sensitive avionics and industrial automation installations, while preserving mating reliability with 34 solder cup contacts. Application: high-density panel assemblies with space constraints and frequent field maintenance. Feature → Business Impact → Application: The 1/3 Bayonet coupling provides fast, secure mating, minimizing downtime during maintenance and field upgrades. This improves maintenance turnaround and uptime in harsh environments such as factory floors and rugged outdoor installations. Feature → Business Impact → Application: Cadmium plating offers corrosion resistance, extending service life in aggressive environments. This supports longer intervals between preventive maintenance and reduces lifecycle costs in energy, automation, and process industries. Feature → Business Impact → Application: The straight backshell adaptor and Y orientation streamline harness routing and connector alignment, reducing installation errors and rework. Application: panel-mounted equipment with predefined harness paths and multi-axis installation scenarios. Feature → Business Impact → Application: 34 contact positions with Solder Cup contacts deliver robust electrical performance across high-speed or signal-rich applications, supporting reliable data and power transfer in automation networks. Application: robotics, packaging lines, and industrial control systems requiring stable connections.
