FAQs
The 85100A2039PX50 is a MIL-DTL-26482 SI qualified square flange receptacle designed for compatibility with MIL-spec harnesses that use a 39-position, solder-cup contact arrangement. It ships with the connector and features a straight backshell adaptor and X orientation, enabling straightforward integration with existing fixation patterns and panel cutouts in aerospace and defense kill chains.
Key specs include 39 contacts in a compact 39‑position layout, solder cup contact type, cadmium plating for corrosion resistance, aluminium shell, shell size 20, and an operating temperature range from -40 °C to 125 °C. It uses a 1/3 bayonet coupling for secure mating and has a square flange receptacle form factor for robust mounting in vibration‑prone environments.
Yes. The Eaton 85100A2039PX50 is MIL-DTL-26482 SI qualified, which aligns with stringent aerospace and defense interconnect standards. Its environmental tolerance (REACH compliance) and high-density 39‑pin configuration in a lightweight aluminium shell make it well-suited for mission-critical harnesses, aircraft systems, and military equipment requiring reliable MIL-spec interconnects.
This receptacle carries MIL-DTL-26482 SI qualification, ensuring MIL-spec interconnect performance. It also adheres to REACH environmental compliance, supporting sustainability and regulatory alignment across global supply chains. The combination of these certifications helps reduce risk in regulated programs and simplifies supplier qualification processes.
The 85100A2039PX50 offers reliable, vibration-resistant mating and a quick 1/3 bayonet coupling that reduces assembly and maintenance time. High-density 39-contact layout lowers harness complexity, which can translate to shorter assembly cycles, fewer field failures, and lower total cost of ownership in programs with extensive interconnect requirements.
