FAQs
This receptacle is designed for seamless pairing with the Souriau 851 series backnut and accessory line. The Z orientation and 1/3 bayonet coupling facilitate quick, secure mating in panel assemblies, while the 36 solder cup contacts align with standard 851 series contact layouts. Always verify shell size, mating face, and torque specs per the 851 series installation guide to ensure optimal performance.
Key specs include 36 contact positions with socket (female) solder cup contacts, backnut mounting, cadmium plating on an aluminium shell, operating from -40 °C to 125 °C, and REACH compliance. The square flange receptacle supports a straight backshell and 34.5 mm length, making it suitable for high-vibration environments where signal integrity and robustness are critical.
Yes. The MIL-DTL-26482 SI qualification and Souriau 851 series heritage make it appropriate for aerospace, defense, and rugged industrial automation. Its high contact density, corrosion-resistant cadmium plating, and robust mechanical interface support mission-critical panels, control systems, and instrumentation exposed to vibration, temperature extremes, and harsh environments.
The connector is MIL-DTL-26482 SI qualified, providing a clear standard for performance under military and aerospace conditions. It is REACH compliant, addressing environmental impact concerns. When selecting for space or defense programs, cross-check with program-specific regulatory requirements and documentation to ensure alignment with supplier quality and qualification processes.
The 85100E2236SZ50 offers a reliable, durable mating interface with a straightforward backnut installation, reducing commissioning time and maintenance intervals. Its high-density 36-contact arrangement lowers harness complexity and spare-part variety. Over the lifecycle, the SAS-compliant architecture and corrosion resistance contribute to lower replacement costs and improved uptime in critical automation assets.
