MIL-DTL-26482 SI qualification ensures the Eaton 85100A1811PW50 MIL-DTL-26482 is compliant with demanding aerospace and defense interface standards, delivering reliable mating under vibration and temperature cycling. The square flange receptacle paired with a straight adaptor and a 1/3 bayonet coupling provides secure retention while enabling rapid field installation. In practice, this reduces assembly time, minimizes mis-mating risk on complex harnesses, and supports consistent performance across equipment subjected to harsh operating conditions. Cadmium plating on an aluminium shell offers robust corrosion resistance while keeping weight low, extending service life in coastal, maritime, or outdoor environments. The design translates to lower maintenance costs and fewer unplanned outages for fielded systems. With 11 contacts in the configuration, it supports multi-wire harnessing in a compact footprint, making it a practical choice for avionics, industrial automation panels, and defense-grade equipment requiring reliable, long-term connectivity. Contact delivery is loaded solder cups, with a W orientation that simplifies plug-and-receptacle alignment during assembly. The 11-position layout aligns with common harness schemes, and the accompanying backshell adaptor enhances cable protection and EMI shielding where needed. Offering compatibility across the Souriau 851 series, this connector family reduces spare-parts diversity and improves procurement velocity for aftermarket repairs and original equipment manufacturing. Operating from -40 °C to 125 °C, the unit withstands extreme temperatures without performance loss. The compact aluminium shell size 18, 41 mm length, and 33.7 mm width/height create a small but sturdy profile ideal for tight-panel installations. Overall, the Eaton 85100A1811PW50 supports safer, compliant, and cost-efficient connectivity in aerospace, rail, and rugged industrial environments through a standardized, SI-qualified interface.
