MIL-DTL-26482 SI qualification provides proven reliability in military and aerospace-grade applications, reducing field failures and warranty costs while enabling compliant procurement processes. This is paired with a square flange receptacle design and straight adaptor, which simplifies panel mounting and mating in tight spaces, improving installation speed and reducing downtime during upgrades. Cadmium plating on an aluminium shell delivers corrosion resistance in moisture and salt exposure environments, extending service life and lowering maintenance intervals for outdoor or industrial plants. The product uses 8 solder cup contacts, arranged in an 8-cavity configuration, delivering robust, soldered connections that support higher current and secure electrical performance under vibration. The 1/3 bayonet coupling combines quick, secure mating with a proven latch mechanism, while the fast-on interface and connector orientation X streamline harness routing and cable management in compact enclosures. Delivered with connector options ensures plug-and-play integration with existing Souriau 851 series components, reducing design risk and accelerating time-to-value. With a 48 mm length, 26.5 mm width, and 26.5 mm height, the 12-shell size fits compact panels without compromising contact density or reliability, making it suitable for aerospace, defense, and rugged automation scenarios.
