Feature → Business Impact → Application: The MIL-DTL-26482 SI qualification ensures a predictable, standardized interface across critical programs, reducing system integration risk and streamlining supplier qualification. In practice, this translates to lower integration lead times and fewer late-stage design changes in aerospace, defense, and industrial equipment programs. Application: used in high-reliability harness assemblies where consistent mating and environmental performance are required. Feature → Business Impact → Application: 26 contact cavities with socket (female) solder cup contacts deliver dense wiring in a compact form factor, enabling designers to maximize channel count without expanding panel footprint. Application: ideal for wire-to-wire and wire-to-board connections in avionics bays, vehicle harnesses, and robotics systems. Feature → Business Impact → Application: cadmium plating on an aluminium shell provides robust corrosion resistance and lightweight strength, improving lifecycle reliability and reducing maintenance frequency in corrosive or humid environments. Application: preferred for coastal or high-dirt operations common in industrial automation and defense assets. Feature → Business Impact → Application: straight backshell with adaptor and 1/3 bayonet coupling ensure quick, secure mating and easy field rework when configurations change, cutting down downtime during service events. Application: frequent-module swaps and reconfigurable assemblies in ground support equipment and aircraft interiors. Feature → Business Impact → Application: Z orientation and loaded contact delivery simplify installation, ensuring correct alignment and faster harness terminations, which lowers training time for technicians and accelerates deployment in mission-critical systems. Application: factory automation, military ground vehicles, and maritime equipment requiring fast, reliable connectors. Feature → Business Impact → Application: environmental compliance with REACH and a proven Souriau 851 platform enhances supply chain resilience, reducing regulatory risk and improving long-term availability. Application: programs with strict environmental and vendor-qualification requirements in aerospace and defense.

FAQs
The Eaton 85100AC1626SZ50 is a MIL-DTL-26482 SI qualified Souriau 851 series square flange receptacle designed for 26‑way, socket (female) solder‑cup contacts. It mates with compatible 851 series plugs using a 1/3 bayonet coupling and Z‑ orientation, and ships delivered with a connector backshell adaptor to simplify field installation.
This receptacle features 26 contacts, solder cup contact type, cadmium plating on an aluminium shell, and a straight backshell with Z orientation. It measures 51 mm long, 31.3 mm wide, and 31.3 mm high with a 16 shell size, supporting operation from -40 °C to 125 °C.
Yes. It is MIL-DTL-26482 SI qualified for rugged environments and complies with REACH. The cadmium-plated aluminium shell provides corrosion resistance, while the square flange receptacle design and 26‑way layout enable reliable mating in vibration, temperature extremes, and aerospace or defense harness applications. It supports long-term deployments in challenging industrial and transportation environments.
Consider using the straight backshell adaptor and 1/3 bayonet coupling to ensure quick, secure mating. The connector is delivered with contacts loaded and a Z orientation; use solder cup terminals for wire harness leads, and ensure aluminium shell cadmium finish compatibility with your enclosure coatings and mounting hardware.
The 85100AC1626SZ50 offers durable MIL‑DTL‑26482 performance, extended service life in temperature extremes, reduced maintenance downtime, and compatibility with Souriau 851 series inventories. Its robust materials and proven mating geometry lower field rework, while REACH compliance reduces regulatory risk over long-term deployments in aerospace, defense, and industrial systems.
