Feature → Business Impact → Application: The 85100E2236PX50 uses a square flange receptacle with backnut, cadmium plating, and a 1/3 bayonet coupling to deliver rugged, low-loss connections in tight confines. This translates to improved vibration resistance and secure mating in dynamic environments, enabling reliable aerospace and defense interconnects with minimal maintenance. Application: install in equipment where a compact, lightweight aluminium shell (Shell size 22) and 36-position layout are required, such as avionics bays or rugged industrial controls. Feature → Business Impact → Application: Solder Cup contact delivery with male pins facilitates fast, field-friendly termination and solder reliability, reducing assembly time and field repair costs. Application: ideal for assemblies requiring 36 contact cavities in a straight backshell configuration with X orientation. Feature → Business Impact → Application: Cadmium plating provides corrosion resistance in challenging environments, helping extend service life and lowering lifecycle costs. Application: suitable for environments where exposure to humidity or salt spray is possible, such as outdoor equipment enclosures. Feature → Business Impact → Application: The 1/3 bayonet coupling and straight backshell angle support straightforward alignment and quick mating/disengagement, reducing tool requirements and installation time in production lines. Application: beneficial for high-volume programs needing repeatable, quick-connect interchanges. Feature → Business Impact → Application: Product designed for MIL-DTL-26482 SI qualification with a 34.5 mm depth, 40 x 40 mm footprint, and 50 g weight, delivering a high power-to-weight ratio for compact systems. Application: aerospace and other weight-sensitive platforms. While addressing common objections about complex tooling, this connector uses familiar Souriau 851 series interfaces, aiding supplier consistency and training. Feature → Business Impact → Application: Environmental compliance with REACH ensures regulatory alignment across global supply chains, smoothing procurement for multinational programs.
