Feature MIL-DTL-26482 SI qualification and REACH compliance ensure regulatory readiness and reliable operation in aerospace, defense, and industrial automation environments. The 85100A1419SY50 uses an aluminium shell with cadmium plating, combining mechanical strength with excellent EMI shielding characteristics in demanding applications. This lean, bayonet-driven design is optimized for fast, repeatable mating cycles, reducing test time and facilitating program milestones. Feature The 19-contact, socket solder-cup configuration provides high-density connectivity for signal and power paths while preserving clean, low-inductance transitions. Cadmium plating offers proven corrosion protection, and the aluminium shell keeps weight to a minimum for dynamic equipment. The 1/3 bayonet coupling enables quick field mating, improving installation efficiency and field serviceability. Feature Backshell adaptor with straight backshell angle supports efficient harness routing and strain relief. Orientation Y and delivered-with-connector options simplify integration with existing harnesses and test jigs, reducing assembly steps in production lines and contractor installations. Feature Compact 41 mm length, 28.9 mm width, 28.9 mm height, and a 26.8 g weight deliver a compact, robust interconnect suitable for densely packed equipment. Operating temperature range from -40 °C to 125 °C enables use in unconditioned environments while maintaining reliable contact integrity. Feature Receptacle type Square Flange Receptacle with 19 contacts supports standardized panel mounts and cross-program interchangeability. The combination of square flange geometry and straight orientation reduces alignment risk during installation, while compatibility with Souriau 851 series components streamlines spares and upgrades. Feature Practical considerations and objections: if cadmium finishes are restricted in a program, we can discuss RoHS-compliant alternatives or cadmium-free variants while preserving mechanical integrity and contact performance. For high-reliability environments, this design delivers predictable mating cycles and low failure rates.
