Feature → Business Impact → Application: The 85100E2025SX50 uses a square flange receptacle with a backnut, CADMIUM plating, and an aluminium shell, which yields superior mechanical robustness and corrosion protection. This translates to longer service life and reduced maintenance costs in high-vibration environments, ideal for aerospace, defense, and heavy industry harnesses. Application: In harsh environments where space is constrained, its 34.5 mm length and 36.9 mm width/height with a 25‑position layout enable dense, reliable wiring across control panels and harness routing. Feature → Business Impact → Application: 1/3 Bayonet coupling provides fast, repeatable mating and reduces installation time, improving field readiness and operator efficiency. Application: Useful in portable equipment and autonomous systems where quick field replacement is critical. Feature → Business Impact → Application: Solder Cup contact delivery supports robust, high‑current or signal connections with low contact resistance, ensuring signal integrity in demanding automation applications. Application: Suitable for backplane interfaces and harness assemblies demanding precise alignment and repeatable performance. Feature → Business Impact → Application: Cadmium plating provides durable corrosion resistance in challenging environments, while the aluminium shell keeps weight low and heat dissipation favorable. Application: Beneficial in radar, industrial sensors, and robotic subsystems requiring durable, lightweight components.
