Feature → Business Impact → Application: MIL-DTL-26482 SI qualification ensures traceable performance under stringent military standards, reducing field failures and warranty costs. This translates to higher system uptime in aircraft, ground vehicles, and rugged equipment where dependable interconnects are mission-critical. Application: defense/aerospace harnesses and avionics with tight tolerances. Feature → Business Impact → Application: 41 contact positions (41 cavities) maximize functionality in a single receptacle, enabling dense interconnects and simplified cable management in compact frames. Application: avionics bays and sensor suites requiring high channel counts. Feature → Business Impact → Application: 1/3 Bayonet coupling offers quick, secure mating and reliable retention during vibration, cutting maintenance time and improving assembly throughput. Application: field service and assembly lines that value rapid, repeatable connections. Feature → Business Impact → Application: Cadmium plating provides corrosion protection, extending service life in corrosive environments common to aerospace and industrial applications. Application: exposure-prone outdoor and vehicle environments. Feature → Business Impact → Application: Aluminium shell with 20-size backshell configuration delivers a lightweight, rigid enclosure that enhances thermal management and mechanical resilience. Application: weight-critical platforms and thermal-dense equipment. Feature → Business Impact → Application: Solder Cup contact type and loaded contact delivery reduce field crimping and insertion issues, improving reliability and install times. Application: assembly with solder connections on wire harnesses. Finally, the delivered-with-connector option simplifies procurement and reduces integration risk for system integrators.
