Feature → Business Impact → Application: The 85100AC1626S50 uses a straight backshell and adaptor design with a square flange receptacle, delivering straightforward panel mounting and reliable mating in tight spaces. This translates to reduced installation time and fewer alignment issues on assembly lines or in field service, improving overall uptime for machinery and automation systems. Application-wise, the 26-contact, solder Cup configuration supports dense signal and power paths in high-density control cabinets, enabling compact, cost-efficient wiring schemes for CNCs, robotics, and substations. Feature → Business Impact → Application: Cadmium plating provides corrosion resistance in harsh environments, extending service life and lowering maintenance costs for outdoor equipment and military-grade applications. This is particularly relevant for aerospace ground-support equipment and mobile automation platforms that encounter moisture, dust, or salt exposure. Feature → Business Impact → Application: The 1/3 bayonet coupling offers a secure, vibration-resistant connection that simplifies field mating and minimizes risk of loose connections under vibration, which is critical in heavy machinery and aircraft systems. Feature → Business Impact → Application: Aluminium shell material reduces weight without sacrificing strength, enabling lighter enclosures and easier handling during installation or retrofits in automated lines. Feature → Business Impact → Application: The receptacle supports a 26-contact configuration with clear orientation (N) and delivered-with-connector options, simplifying inventory management and spare-part compatibility across the Souriau 851 family for customers upgrading legacy systems or migrating to MIL-DTL-26482-compliant solutions. The combination of mechanical robustness, environmental resilience (REACH), and validated performance ensures predictable electrical characteristics, enabling engineers to meet regulatory and uptime targets while optimizing total cost of ownership in industrial automation, aerospace, and defense projects.

FAQs
The 85100AC1626S50 is part of the Souriau 851 series and is designed for compatibility with a square flange receptacle interface, 26 solder cup contacts, and a straight backshell with N orientation. It supports 1/3 bayonet coupling and is delivered with connector options, making it straightforward to pair with other Souriau 851 components and existing MIL-DTL-26482 assemblies.
MIL-DTL-26482 SI qualification indicates conformance to a recognized defense/aerospace standard, ensuring mechanical integrity, environmental robustness, and reliable electrical performance under vibration and temperature cycling. For this receptacle, it translates to proven reliability in harsh conditions, repeatable mating, and suitability for demanding programs such as aerospace and military ground platforms.
The connector is specified for an operating range from -40 °C to 125 °C, allowing reliable operation in cold start conditions and high-temperature environments typical of aerospace, industrial automation, and vehicle applications. This broad range supports applications with extreme temperature shifts and ensures electrical performance consistency across service life.
Yes. The 85100AC1626S50 combines an aluminium shell, cadmium plating, 26 solder cup contacts, and MIL-DTL-26482 SI qualification, making it suitable for aerospace, defense, and rugged industrial automation. Its 1/3 bayonet coupling provides secure mating under vibration, while the N-oriented straight backshell supports compact installations in precision systems.
Plan for careful soldering of all 26 contacts using compatible solder methods and proper thermal management to avoid cold joints. Use the delivered-with-connector option for compatibility checks, ensure correct mating with the corresponding Souriau 851-series receptacles, and maintain interconnect cleanliness to preserve signal integrity. Also verify panel cutouts and backing hardware to minimize misalignment during mating.
