Eaton 85100A1811SZ50 Receptacle - SI Qualified
Part Number: 85100A1811SZ50
Quick Summary
Eaton Souriau 851 series MIL-DTL-26482 SI qualified is a square flange receptacle for rugged, high-reliability connections. Engineers often struggle to maintain mating reliability in harsh environments while meeting tight installation tolerances. This connector delivers MIL-DTL-26482 SI qualification with REACH environmental compliance, supporting aerospace and industrial standards. The compact 41 mm length, 11-position layout, and pre-loaded solder cup contacts help reduce assembly time and inventory complexity, while a lightweight aluminium shell provides corrosion resistance. With straight backshell, Z orientation, and a robust 1/3 bayonet coupling, it combines performance with ease of integration in demanding panel designs and harness programs.

MIL-DTL-26482 SI qualified design ensures MIL-grade reliability and compatibility with mission-critical systems in aerospace, defense, and rugged industrial environments, translating to lower field failure risk and longer service life. By delivering 11 solder cup contacts pre-loaded in a compact 41 mm long receptacle, this solution reduces pre-assembly steps and wiring errors, accelerating production and commissioning. The 1/3 bayonet coupling provides fast, lockable mating under vibration, improving on-site efficiency and operator confidence in tight spaces. An aluminium shell with cadmium plating delivers a lightweight yet corrosion-resistant envelope, cutting maintenance costs and enabling operation across challenging climates. The straight backshell adaptor and Z orientation simplify panel installation, enabling predictable mounting footprints and faster retrofits. Operating temperature from -40 °C to 125 °C broadens the applicability to outdoor, on-machine, and extreme-temperature environments, supporting longer system uptime and reduced replacement cycles. Delivered with contacts installed, the unit minimizes hardware handling and supports repeatable electrical performance across assemblies, helping you achieve consistent signal integrity and reduced testing times.

FAQs
Begin with the panel cutout sized for shell size 18 and the square flange footprint. Align the orientation to match the Z configuration, then slide the backshell adaptor into place and engage the 1/3 bayonet coupling until a positive mate is felt. The contacts are pre-loaded, reducing wiring steps; verify the solder cup terminations follow your harness routing and insulation practices for maximum reliability.
The connector layout provides 11 contact positions with socket (female) solder cup contacts delivered pre-loaded. This 11-position configuration supports mixed signaling and power applications within a single receptacle, enabling compact harness design while preserving signal integrity and mounting efficiency.
Yes. It operates from -40 °C to 125 °C and uses an aluminium shell with cadmium plating for corrosion resistance. MIL-DTL-26482 SI qualification reinforces reliability under vibration and shock, making it suitable for aerospace, defense, and rugged industrial automation deployments.
The 85100A1811SZ50 is MIL-DTL-26482 SI qualified and REACH compliant, ensuring both military-grade mechanical/electrical performance and environmental responsibility. Always consult the official datasheet for latest certification disclosures and any region-specific regulatory requirements relevant to your program.
Pre-loaded contacts shorten assembly time and reduce wiring mistakes, improving first-pass yield in panel assemblies. The lockable 1/3 bayonet coupling speeds mating, while the lightweight aluminium shell reduces overall device weight. Collectively, these factors translate to lower labor costs, faster field replacements, and improved uptime in high-demand production environments.
