FAQs
The 85100E1418SX50 follows the same 851-series footprint for backnut square flange mounting and 18-contact configuration, ensuring straightforward cross-compatibility with compatible Souriau 851 ecosystem assemblies. Its backnut/backshell design simplifies panel mounting, while the 1/3 bayonet coupling provides a secure, repeatable mating cycle. For a seamless upgrade, verify shell size and contact layout against your current harness drawings and ensure connector orientation matches the X-axis alignment.
With 18 solder cup contacts arranged in a compact 18-position layout, the receptacle supports dense wiring harnesses while maintaining reliable electrical performance. Solder cup contacts simplify field assembly and rework, improving repairability. The aluminium shell with cadmium plating provides both mechanical robustness and corrosion resistance, helping maintain signal integrity in harsh environments.
Yes. The 85100E1418SX50 is designed for demanding aerospace applications, delivering MIL-DTL-26482 SI qualification for secure mating under vibration, coupled with a square flange receptacle format that fits tight panel spaces. Its backnut and straight backshell orientation support robust mounting, while the operating temperature range of -40 °C to 125 °C covers most aviation environments. REACH compliance further supports regulatory requirements for long-term deployments.
The receptacle demonstrates REACH environmental compliance and MIL-DTL-26482 SI qualification, aligning with military standards for high-reliability connectors. Cadmium plating provides corrosion resistance, though users should confirm any customer-specific plating policies. Always verify compatibility with your program’s environmental spec sheets, including RoHS considerations and applicable aviation or defense procurement requirements.
The combination of a durable aluminium shell, cadmium plating, and robust solder cup contacts contributes to extended service life with reduced maintenance needs. The backnut backshell and secure 1/3 bayonet coupling minimize mating wear and panel loosening, lowering field service time. For ROI, plan for standard inspection intervals on mating interfaces and replace connectors at agreed wear thresholds to avoid unexpected downtime.
