MIL-DTL-26482 SI qualification provides reliability in mission-critical equipment. The 85100A2025PX50 uses a square flange receptacle with a straight backshell and 1/3 bayonet coupling for fast, secure mating in demanding environments. This translates to reduced rework and improved uptime in aircraft, military systems, and rugged industrial settings. The 25-contact layout supports high-density wiring, enabling compact control panels and scalable sensor networks without sacrificing signal integrity. Cadmium plating on an aluminium shell delivers corrosion resistance while keeping weight low, which lowers total cost of ownership in long-life assemblies. Solder Cup contacts simplify termination and maintenance, with a male pin configuration that fits common Souriau mating interfaces for streamlined inventory management. The X connector orientation and delivered-with-connector option minimize field labor and misalignment risks during installation. Operating from -40 °C to 125 °C and REACH-compliant materials further assure performance in extreme ambient conditions while meeting regulatory expectations for global deployments.

FAQs
The 85100A2025PX50 is a square flange receptacle with a straight backshell and a 1/3 bayonet coupling, designed for compatibility with Souriau 851 series mating interfaces. It uses 25 solder cup contacts in aluminium shell size 20 and offers X orientation for simplified wiring paths. It is delivered with the connector, reducing additional hardware requirements and enabling faster field installation.
This connector is MIL-DTL-26482 SI qualified, providing a recognized standard for high-reliability applications. It also carries REACH compliance for materials, supporting regulatory acceptance in regions with environmental restrictions. The operating temperature range of -40 °C to 125 °C further ensures suitability for harsh environments typical in aerospace, defense, and industrial automation.
Yes. The Eaton 85100A2025PX50 is part of the MIL-DTL-26482 SI qualified family, specifically the Souriau 851 series, designed for high-reliability aerospace and defense environments. Its aluminium shell, cadmium plating, and robust coupling (1/3 bayonet) support vibration resistance, EMI considerations, and durable mating in challenging flight and ground-based systems.
Plan for a straight backshell with an adaptor in the assembly, and ensure proper alignment using the X orientation during mating. The 25-contact configuration requires careful harness routing to avoid crosstalk; solder cup contacts simplify termination on PCBs or harnesses. Weight is modest at 40.8 g, and overall dimensions (44 mm length x 36.9 mm height and width) fit compact panels while preserving mechanical robustness.
The MIL-DTL-26482 SI qualification and REACH compliance provide regulatory confidence and long-term reliability, reducing maintenance and field failures. High-density 25-contact layouts enable compact, scalable control networks, while the durable aluminium shell and cadmium plating offer corrosion resistance in harsh environments. Fast mating with a 1/3 bayonet coupling lowers installation time and labor costs, improving overall ROI in complex automation systems.
