Eaton 85100A2221P50 Receptacle - MIL-DTL-26482
Part Number: 85100A2221P50
Quick Summary
The Eaton 85100A2221P50 Receptacle is a MIL-DTL-26482 SI qualified square flange connector designed for rugged aerospace and industrial equipment. Engineers often struggle to guarantee reliable connections under vibration and wide temperature swings, driving costly downtime. MIL-DTL-26482 SI qualification and REACH compliance help ensure performance and safety in critical applications. This receptacle merges dense 21-pin capacity with a lightweight aluminium shell and cadmium plating, delivering robust electrical performance and corrosion resistance. It also supports field-installation workflow with an adaptor backshell and a clear orientation (N) for consistent mating, helping procurement teams reduce assembly time and lifecycle costs while expanding compatibility across trusted Souriau 851 series systems.

MIL-DTL-26482 SI qualified construction provides verified performance in mission-critical environments, translating to lower field failure rates and reduced maintenance costs in aerospace and harsh industrial settings. The design supports 21 solder cup contacts in a compact 44 mm depth and a 40x40 mm footprint, enabling high-density wiring without compromising reliability, which in turn shortens assembly time and improves system clarity for end users. A 1/3 Bayonet coupling delivers fast, secure mating with vibration resistance, reducing downtime during equipment swaps or reconfigurations in production lines and on aircraft. The aluminium shell with cadmium plating offers a favorable strength-to-weight ratio and corrosion resistance, extending service life in aggressive environments and lowering total cost of ownership. Delivered with connector options and N-oriented alignment simplify panel mounting and ensure repeatable, error-free installations across multiple assemblies, including maintenance and field service.
