Feature → Business Impact → Application: The 85100E2234PX50 uses a square flange receptacle with a backnut, enabling secure panel mounting and vibration resistance in demanding environments, which reduces connector loosening risk during operation in aircraft and stationary equipment. This translates to improved uptime and lower maintenance costs in aerospace and defense systems that demand reliable, long-life connections. Application: Square flange backnut designs are ideal for front-panel installations where space is constrained and alignment accuracy is critical, such as automation panels in heavy industry. Feature → Business Impact → Application: The 34-pin, solder-cup contact arrangement provides a dense, high-reliability interface with straightforward solder termination, helping manufacturers reduce assembly time and ensure consistent electrical performance across complex wiring harnesses. Application: Used in 34-position interconnects for data and power in robotics and control cabinets. Feature → Business Impact → Application: Cadmium plating and an aluminium shell offer corrosion resistance and lightweight strength, improving lifecycle performance in outdoor or harsh indoor environments, which lowers replacement costs and extends service intervals. Application: Suitable for rugged deployments in defense platforms and industrial automation equipment that experience wide temperature swings. Feature → Business Impact → Application: The 1/3 bayonet coupling and straight backshell simplify mating and maintenance, enabling faster field servicing and lower training requirements for technicians. Application: Ideal for service-heavy applications where quick connection/disconnection is valuable. Feature → Business Impact → Application: Operating temperature range from -40 °C to 125 °C ensures reliable operation in extreme climates, providing design flexibility for equipment deployed across different geographies. Application: Critical for equipment used in aerospace ground testing, mining instrumentation, and outdoor automation installations. Throughout, compatibility with Souriau 851 series design practices supports standardization across multi-vendor assemblies, reducing part proliferation and improving supply chain resilience.

FAQs

The 85100E2234PX50 is part of the Souriau 851 series and uses a square flange receptacle with a backnut, 34 solder-cup male contacts, and a 1/3 bayonet coupling. It matches other Souriau 851 family panels and backnut assemblies, enabling consistent mechanical and electrical interfaces across multi-block interconnects in aerospace, defense, and industrial applications.
MIL-DTL-26482 SI qualification guarantees compliance with a recognized military standard for performance under vibration, temperature, and mechanical stress. For the 85100E2234PX50, this means reliable mating, robust sealing against environmental exposure, and predictable electrical continuity, reducing field failures in aircraft, military vehicles, and heavy-duty machinery.
Yes. The 85100E2234PX50 is designed for high-reliability interconnects used in aerospace, defense, and industrial automation. Its MIL-DTL-26482 SI qualification, cadmium plating, aluminium shell, and backnut design support stringent environmental and mechanical requirements while offering 34-pin capacity and solder-cup contacts for versatile harness terminations.
Plan for panel thickness and mating alignment with the square flange, ensuring the backnut is properly torqued to prevent loosening under vibration. Use the 1/3 bayonet coupling for secure coupling, and confirm orientation X to match the harness routing. Verify solder-cup terminations are clean and insulated to prevent short circuits or signal interference.
Cadmium plating provides corrosion resistance but requires proper handling and disposal per environmental guidelines. Aluminium shells keep weight light while maintaining strength. For lifecycle planning, consider inspection for coating wear, ensure compatible mating surfaces are clean, and align with REACH compliance requirements to minimize environmental impact and regulatory risk.
