FAQs
The 85100AC124S50 uses a straight backshell with a 1/3 bayonet coupling and a square flange receptacle format, enabling quick mating and robust retention in vibration-prone enclosures. Ensure panel cutouts match the 48 mm length and 26.5 mm width/height, and that solder cup contacts are prepared with proper flux, heat control, and insulation to maintain signal integrity across temperature extremes.
This receptacle is MIL-DTL-26482 SI qualified, confirming compatibility with high-rel environments where vibration, impulse, and environmental exposure are common. The aluminium shell with cadmium plating provides mechanical resilience and corrosion protection, while the four solder cup contacts ensure reliable continuity in multi-conductor harnesses typical of defense and aerospace assemblies.
Solder cup contacts offer straightforward field and factory soldering, providing strong, repeatable electrical connections with good mechanical stability. For the 85100AC124S50, four solder cups support a 4-position circuit, enabling compact wiring harnesses and easier inspection, which translates to reduced rework and improved maintenance turnaround in control panels and avionics environments.
Yes. The 85100AC124S50 is designed for compatibility with Souriau 851 series configurations, featuring a straight backshell and 1/3 bayonet coupling. This ensures consistent mating geometry, streamlined inventory, and easier upgrades or replacements within existing 851-series installations across aerospace, defense, and industrial automation programs.
Choosing this MIL-DTL-26482 SI qualified receptacle reduces maintenance intervals thanks to corrosion resistance and robust mechanical design, while the plug-and-play compatibility with 851 series ecosystems shortens assembly time. The result is lower lifecycle costs, improved uptime, and predictable performance in harsh environments common to aerospace, defense, and heavy industry.
