FAQs
Plan for the square flange mounting with the straight backshell adaptor and 1/3 bayonet coupling. Ensure mating with a compatible Souriau 851-series receptacle and verify cadmium plating integrity for corrosion resistance. Use solder cup contacts for reliable field terminations and maintain proper torque on mounting hardware to preserve seal and alignment in vibration-prone environments.
Yes. The 85100A2234PW50 is MIL-DTL-26482 SI qualified, designed to deliver rugged performance in demanding environments. This qualification supports reliable electrical performance under vibration and temperature cycling, making it suitable for aerospace, defense, and industrial applications that require MIL-spec interconnects.
Best suited for high-density interconnect needs in aerospace, defense, and industrial automation. The 34-contact configuration supports complex wiring, while the aluminium shell and cadmium plating offer durability in exposed or temperature-variable environments. Its bayonet coupling and W orientation simplify installation in tight panels and equipment bays.
Establish routine inspection of the solder cups and contact integrity to prevent signal degradation. Confirm that the cadmium plating remains intact to resist corrosion, and check alignment during mating to avoid wear on the 34 contacts. Use compatible cleaning procedures and avoid aggressive solvents that could affect the aluminium shell or seal interfaces.
Compatibility with Souriau 851 series accessories reduces spare parts inventory and enables plug-and-play integration across multiple platforms. This translates to faster maintenance cycles, lower training costs for technicians, and improved uptime by allowing quick field replacements using standardised components.
