FAQs
The 85100E128PZ50 is a square flange receptacle in the Souriau 851 series, featuring an 8-contact, Pin (Male) solder-cup arrangement with 1/3 Bayonet coupling and backnut mechanical integration. It is designed to mate with corresponding MIL-DTL-26482 SI-qualified plug housings and round out-panel assemblies, offering reliable engagement in rugged environments.
Installation uses the backnut backshell to secure the receptacle to the panel, with the connector oriented to Z. The 1/3 Bayonet coupling enables quick mating, while the delivered-with-connector configuration reduces assembly steps. Ensure correct panel cutout and alignment with the mating plug to maintain seal integrity and signal contact reliability.
Yes. The connector operates from -40 °C to 125 °C, providing broad thermal tolerance for industrial automation and aerospace applications. The aluminium shell and cadmium plating contribute to mechanical robustness and corrosion resistance, while MIL-DTL-26482 SI qualification confirms compliance with stringent military standards.
The 85100E128PZ50 carries MIL-DTL-26482 SI qualification and REACH compliance, supporting regulatory alignment for aerospace and industrial environments. The cadmium plating, while providing corrosion resistance, should be assessed against current environmental regulations and replacement strategies if cadmium is restricted in your project.
The combination of MIL-DTL-26482 SI readiness, lightweight aluminium housing, and robust solder-cup contacts reduces maintenance needs by lowering failure rates and simplifying field servicing. With rapid 1/3 Bayonet mating and a compact footprint, installation time is minimized, delivering faster deployment and improved total cost of ownership in high-density control panels.
