Feature → Business Impact → Application: The 61-position contact layout increases channel density, enabling high-throughput connections in limited panel space, which translates to fewer assemblies and lower cabling costs in control cabinets and avionics bays. The result is improved efficiency during system integration and easier future scalability for automation upgrades. Feature → Business Impact → Application: Cadmium plating on an aluminum shell provides robust corrosion protection and EMI resilience in outdoor or adverse environments, reducing maintenance cycles and extending service life for offshore, rail, or industrial installations. Feature → Business Impact → Application: The straight backshell with adaptor option and Z orientation simplifies installation and cable routing, enabling faster field mating and reducing commissioning time in tight enclosures and on-vehicle panels. Feature → Business Impact → Application: Solder Cup contact delivery supports quick field repair and reliable solder connections, which lowers rework rates and improves joint integrity in rugged equipment. Feature → Business Impact → Application: The 1/3 bayonet coupling delivers rapid, vibration-resistant mating, cutting down shutdown time during equipment swaps and field servicing in aerospace consoles or automation panels. Feature → Business Impact → Application: REACH compliance and MIL-DTL-26482 SI qualification provide regulatory confidence and long-term supply chain stability, supporting quality-focused procurement across regulated industries. Feature → Business Impact → Application: The square flange receptacle format and 24 shell size harmonize with standard chassis footprints, enabling straightforward retrofits and compatible upgrades in legacy automation systems.
