MIL-DTL-26482 SI qualified design provides proven interoperability and regulatory confidence, reducing qualification time and field rework in aerospace and industrial automation applications. Its 5-cavity layout and solder cup contacts enable secure, soldered terminations with consistent electrical performance, supporting reliable signal integrity in demanding environments. The aluminium shell with cadmium plating delivers a lightweight yet durable enclosure that resists corrosion while maintaining mechanical strength for harsh factory floors and on-aircraft installations. The 1/3 bayonet coupling offers quick mating and positive retention, speeding assembly in production lines and simplifying field maintenance without sacrificing reliability. A straight backshell (adaptor) and W orientation reduce cable routing complexity and improve fit in compact enclosures. Operational temperature range of -40 °C to 125 °C and REACH compliance ensure performance across extreme conditions and global supply chains. Delivered with connector options streamline installation and reduce accessory sourcing complexity, supporting faster time-to-ink-in and uptime in high-demand environments.
