Eaton 85100AC84S50 Square Receptacle - MIL-DTL-26482

MIL-DTL-26482 SI qualification ensures mechanical interchangeability and environmental resilience across the Eaton Souriau 851-series, allowing designers to reuse existing enclosures and panels without redesigning cutouts or interfaces. This reduces development risk and qualification cost for aerospace, rail, and rugged industrial automation programs, delivering reliable performance under wide temperature, vibration, and EMI conditions. The 85100AC84S50 also benefits from cadmium plating and an aluminium shell that withstand harsh environments while keeping weight and mass budgets in check. The 4-contact layout paired with a 1/3 bayonet coupling delivers secure, positive mating even in high-vibration applications. By minimizing mating force and ensuring repeatable connection integrity, it lowers maintenance cycles, reduces pull-out events, and supports faster, error-free panel assemblies during assembly lines or on-site upgrades. Cadmium plating on an aluminium shell provides robust corrosion resistance without adding significant weight, extending life in salt-spray, industrial washdowns, or high-humidity environments. The combination aligns with aerospace weight budgets and industrial reliability targets, helping you meet maintenance intervals and lifecycle costs more predictably. Backshell options include a straight adaptor and N-oriented connector arrangement for consistent mating alignment and panel layout. Delivered with connector simplifies procurement and reduces part-number fragmentation; the 21 mm square footprint and 48 mm length support compact enclosures and standardized mounting patterns. Compact form factor, with 21 mm width and height and 48 mm depth, weighs just 13.2 g for low added mass in harnesses and avionics boxes. This helps you optimize space on crowded panels while maintaining the electrical performance expected from MIL-SPEC connectors. Contact delivery is loaded with solder-cup contacts, ready for direct termination to PCB or harness conductors, and the four cavities (#20) match standard Souriau conductor sizes. This reduces install-time, shortens training needs for assembly, and improves repeatability across shift changes.
