FAQs
Start by confirming the shell size and cavity count: 32 cavities in a 40x40 mm square flange with a 1/3 bayonet coupling. Ensure the contact type is Solder Cup with male pins, and that the backshell is the adaptor type with straight orientation. Verify the connector orientation is X and that the mating counterpart is compatible with MIL-DTL-26482 SI qualified interfaces. Review the operating temperature range (-40 °C to 125 °C) to guarantee your environment falls within spec.
Plan for a 44 mm depth and a 40x40 mm mounting footprint to fit the square flange receptacle. Use the straight backshell adaptor to simplify routing, and ensure correct alignment for the X orientation. The 32-contact layout demands careful harness routing to avoid crosstalk and ensure reliable solder cup terminations. Confirm panel cutouts and mounting hardware accommodate the aluminium shell for secure mating.
Yes. The connector operates from -40 °C to 125 °C, covering typical aerospace and harsh-industrial conditions. Cadmium plating provides corrosion resistance, while the aluminium shell keeps weight low for aerospace applications. When used in extreme environments, ensure cable assemblies and gaskets maintain integrity and avoid exposure to corrosive agents beyond spec. Regular inspection of solder joints is recommended in high-vibration settings.
The 85100A2232PX50 carries MIL-DTL-26482 SI qualification, indicating suitability for stringent military and aerospace requirements. It also features cadmium plating for corrosion protection and an aluminium shell to balance strength and weight. Environmental compliance includes REACH considerations, and the design supports durable, long-service performance in regulated industrial ecosystems.
The MIL-DTL-26482 SI qualified design, cadmium plating, and aluminium shell combine to deliver low failure rates in demanding environments, reducing unscheduled maintenance and replacement costs. The high contact density (32 contacts) in a compact form factor saves panel space and simplifies harness design, contributing to faster assembly, easier field servicing, and improved lifecycle economics.
