MIL-DTL-26482 SI qualification delivers high mating reliability and vibration resistance, meaning fewer in-field failures and lower warranty costs. This directly reduces downtime in aerospace, military, and rugged industrial equipment while supporting strict regulatory expectations. The 25-contact configuration enables mixed signal and power transmission in a single connector, streamlining control panel designs and robotics harnesses for faster commissioning and easier maintenance. Cadmium plating enhances corrosion resistance in aggressive environments, extending service life in outdoor, marine, and high-dust applications. The aluminium shell size 20 provides a lightweight, compact footprint, improving enclosure fit and overall system weight without sacrificing durability. A 1/3 bayonet coupling offers quick, secure mating, reducing installation time on high-volume assembly lines and in field service. Solder Cup contacts enable straightforward field terminations, facilitating rapid repairs and easy retrofits in automation cabinets. Delivered with connector options simplify procurement, vendor compatibility, and overall project lead times, supporting lean manufacturing practices and tighter supply chains.
