Feature MIL-DTL-26482 SI qualification combined with 61 contact positions provides a high-density, rugged signal path that meets stringent aerospace and defense reliability requirements. Business Impact The qualification reduces program risk by ensuring a proven interface with traceable performance, enabling tighter supplier controls and fewer field failures. Application Aerospace, defense, and industrial machinery harness assemblies benefit from this reliable, high-contact-density solution. The 1/3 Bayonet coupling simplifies mating and reduces assembly time in production lines and field maintenance, which translates into lower labor costs and faster turnarounds. Feature Cadmium plating on an aluminium shell delivers enhanced corrosion resistance and heat dissipation for harsh environments. Business Impact Expect longer service life in salt spray, high humidity, or dusty environments, decreasing maintenance cycles and replacement costs. Application Outdoor equipment, military vehicles, and aircraft systems demand robust longevity. Feature Straight backshell with adaptor option and delivered connector ensures straightforward integration into existing harness designs. Business Impact You gain installation predictability and compatibility with current Souriau 851 series components, minimizing redesigns and spare part inventories. Application OEM harnesses and system integrators expand design freedom while keeping sourcing simple. Feature Cadmium-plated shell size 24 and 53 mm depth with 43.1 mm width/height supports compact, lightweight assemblies. Business Impact Weight management and space optimization become feasible for tightly packed enclosures and high-channel-count installations. Application Avionics racks, naval electronics, and mobile platforms rely on compact, dependable connectors. Feature 61 contacts with solder cup contact delivery enables robust, soldered connections that withstand vibration and thermal cycling. Business Impact Eliminates undecided contact types and reduces rework from poor contact seating. Application Harness terminations, deployed wiring looms, and retrofit kits benefit from consistent performance. Industry Context The Eaton Souriau 851 series is a well-established family in aerospace and defense programs, aligning with common procurement practices and reducing part proliferation. This reduces inventory complexity while maintaining high performance across environments.
