High contact density and compact footprint enable tighter panel layouts and streamlined harness routing. The 85100E1830SX50 delivers 30 solder cup contacts in a square flange receptacle, reducing panel real estate and assembly time while preserving signal integrity in dense interconnect environments. In aerospace and defense harnesses, this translates to lower wiring complexity and faster integration across systems. The 1/3 Bayonet coupling offers quick mating with strong vibration resistance, accelerating field maintenance and minimizing downtime during critical missions. Cadmium plating paired with an aluminium shell provides robust corrosion protection while keeping weight low, supporting longer service intervals and reduced lifecycle costs in aviation and industrial equipment. Solder Cup contacts simplify field terminations and improve reliability on harness assemblies, while the backnut backshell delivers effective strain relief and sealing against contamination. The orientation X and straight backshell maximize installation consistency and reduce mating errors in complex line-ups. With REACH compliance and MIL-DTL-26482 SI qualification, this receptacle supports compliant, repeatable performance across global programs.
