High-density 32-contact interface enables more signal/power paths per connector, reducing panel footprint and overall wiring complexity while delivering reliable electrical performance in demanding environments. The 1/3 bayonet coupling provides quick mating and robust vibration resistance, lowering installation time and minimizing rework on high-vibration equipment. Solder cup contacts simplify field wiring and rework, improving solder joint integrity and long-term reliability in harsh conditions. Cadmium plating on an aluminium shell offers corrosion resistance and light weight, contributing to lower total cost of ownership in aerospace, defense, and industrial automation applications. The adaptor backshell with straight orientation and Y connector positioning streamlines harness routing, simplifies panel cutouts, and supports scalable wiring designs. Operating temperature range from -40 °C to 125 °C ensures performance in extreme environments, while the 32-contact layout supports complex power and signal distribution without sacrificing durability.
