FAQs
To install, align the mating interface with the straight backshell, insert the connector, and rotate the coupling roughly a 60-degree turn to engage the 1/3 bayonet mechanism. Ensure the pins are fully seated and the connector is oriented as indicated by the N orientation. Use compatible mating hardware from the Souriau 851 series to maintain environmental sealing and mating integrity during vibration or thermal cycling.
The 85100AC1811P50 is designed for aerospace, defense, and rugged industrial automation applications requiring MIL-DTL-26482 SI qualification and reliable 11-position wiring. Its square flange receptacle form factor, aluminium shell, and cadmium plating support long-term performance in temperature extremes and vibration, making it well-suited for critical mating interfaces in harsh environments.
Yes, the product listings indicate REACH environmental compliance. This means the connector adheres to European Union chemical safety regulations for long-term exposure and restricts certain hazardous substances. When sourcing for regulated environments, confirm supplier documentation and any regional cadmium usage considerations, and plan for compliant waste handling and recycling where applicable.
The assembly provides 11 solder cup contacts in a single cavity layout, with male pin terminations designed for secure wire or PCB connections. Cadmium plating aids corrosion resistance, while the 51 mm length and 33.7 mm square footprint support compact wiring harnesses. The combination supports reliable, vibration-resistant connections across -40 to 125 °C operating conditions.
Cadmium plating offers corrosion resistance but may require compliance review in cadmium-restricted regions. The aluminium shell minimizes weight while sustaining rigidity, reducing mounting stress and labor for field replacements. Its compatibility with the Souriau 851 series and straight backshell simplifies upgrades or replacements, lowering downtime and inventory complexity over the connector’s lifecycle.
