Eaton 85100A2236PX50 Receptacle - MIL-DTL-26482 SI
Part Number: 85100A2236PX50
Quick Summary
The Eaton 85100A2236PX50 Receptacle delivers MIL-DTL-26482 SI qualified performance for rugged, high-reliability connections. Engineers often struggle with vibration, wide temperature swings, and tight panel space in assemblies. MIL-DTL-26482 SI qualification, REACH compliance, and cadmium plating on an aluminium shell deliver robust, regulator-ready performance. Beyond ruggedness, the 36-position configuration, 1/3 bayonet coupling, and X-oriented design streamline installation and maintenance, reducing touchpoints and downtime for panel builders and system integrators. The connector’s square flange receptacle format consolidates mating interfaces and simplifies enclosure layouts, while cadmium plating provides corrosion resistance in demanding environments. With a compact 44 mm length and 40x40 mm footprint, it fits compact enclosures without sacrificing current and signal integrity.

FAQs
To install, align the receptacle with the mating connector and ensure the X orientation is correct. Engage the 1/3 bayonet coupling for a secure fit, then attach the adaptor backshell to complete the straight backshell assembly. Use solder cup contacts as specified and verify that the 36-contact array is properly seated to avoid intermittent connections in vibration environments.
The 85100A2236PX50 is a square flange receptacle designed to be paired with the corresponding Souriau 851 series plug or compatible MIL-DTL-26482 mating connector. It ships with a connector backshell adaptor and supports a straight backshell. Use the X orientation to align with the host harness and ensure a tight, vibration-resistant connection.
The assembly operates from -40 °C to 125 °C, covering extreme cold starts and high-temperature operation. It features cadmium plating on an aluminium shell and is REACH compliant, ensuring regulatory alignment for many global markets and challenging environments such as outdoor automation or rail applications.
Yes. It is MIL-DTL-26482 SI qualified, which provides proven performance in stringent military and aerospace contexts. The product is REACH compliant and uses cadmium plating, a detail to consider for regulatory guidance in your region. Always verify with your compliance team for RoHS or country-specific requirements in your end market.
With 36 solder cup contacts in a compact 44 mm × 40 mm footprint and a secure 1/3 bayonet coupling, the design minimizes harness complexity and simplifies field maintenance. The aluminium shell reduces weight, while the robust MIL-DTL-26482 SI qualification enhances longevity under vibration and thermal cycling, potentially lowering maintenance costs and downtime.
