MIL-DTL-26482 SI qualified design delivers proven performance in mission-critical environments, reducing program risk and ensuring regulatory alignment for aerospace and defense harnesses. This translates to higher reliability and lower field failure rates, which in turn lowers maintenance costs and downtime. The 11 solder-cup male contacts across 11 cavities supports dense signal and power distribution, enabling tighter harness layouts and improved EMI control in industrial equipment. Cadmium plating paired with an aluminium shell keeps weight down while delivering robust corrosion resistance and thermal performance for harsh environments. A straight backshell adaptor and 1/3 bayonet coupling enable fast, secure mating and straightforward field maintenance, reducing assembly time by eliminating complex alignment steps. The Y connector orientation offers installation flexibility, complementing mixed-harness configurations in aerospace and heavy industry. Delivered with connector content minimizes procurement steps and ensures compatibility across Souriau 851 series ecosystems, improving overall project velocity and supplier coordination. The REACH-compliant construction aligns with global supply chains, supporting compliant sourcing and risk mitigation in regulated programs.
