FAQs
For installation, align the 85100E1811SX50 with the mating counterpart and secure it using the backnut while using the straight backshell orientation. The 1/3 bayonet coupling enables quick engagement, and the 11-socket configuration supports efficient harness routing with solder-cup contacts for reliable, vibration-resistant connections in panel-mounted assemblies.
The receptacle provides 11 contacts in a single 11‑cavity layout with solder cup contact delivery. It uses a socket (female) contact design, is loaded with contacts, and is suitable for high-reliability signal and power applications within its MIL-DTL-26482 framework, ensuring consistent contact performance across temperatures.
Yes. It is MIL-DTL-26482 SI qualified and designed for harsh environments. The aluminium shell is cadmium-plated for corrosion resistance, and the operating temperature range is -40 °C to 125 °C, making it well-suited for aerospace, defense, and industrial automation applications where reliability under vibration and temperature extremes is essential.
Maintenance considerations include managing cadmium plating in accordance with regulatory guidelines and ensuring proper mating force to avoid wear. The backnut backshell simplifies mounting and field servicing, while the solder-cup contacts provide stable wire terminations that support routine inspection and replacement as part of a maintenance program.
Ensure the mating counterpart shares the MIL-DTL-26482 interface and that the receiver and lever alignment correspond to the X orientation. The 85100E1811SX50 is designed to be interchangeable within the Souriau 851 family, using identical footprint and bayonet coupling, which simplifies inventory management and reduces integration risk.
