FAQs
The 85100E128SZ50 is designed to conform to MIL-DTL-26482 SI qualification, ensuring compatibility with SI-qualified assemblies. It features a square flange receptacle, backnut mounting, and a Z orientation, enabling reliable integration with standard Souriau 851 series interfaces and existing harnesses. This compatibility helps streamline procurement and integration while maintaining robust performance under vibration and temperature extremes.
Installation centers on the square flange mounting and backnut mechanism for secure panel attachment. The 32.7 mm length, 26.5 mm width, and 26.5 mm height fit compact enclosures, while the 1/3 Bayonet coupling offers quick mating. Ensure alignment with the connector orientation Z, verify cadmium plating integrity, and use the supplied backnut for a vibration-resistant, sealed interface in demanding environments.
Key specs include eight solder cup contacts, socket (female) contact gender, and Cadmium plating on an Aluminium shell with a 12 shell size. The operating temperature range is -40 °C to 125 °C, and environmental condition is REACH compliant. The connector is delivered with the harness pre-loaded and includes a backnut/backshell configuration suitable for rugged, high-reliability installations.
Yes. The design carries MIL-DTL-26482 SI qualification and a 1/3 Bayonet coupling, which provides secure, vibration-resistant mating. The aluminium shell and cadmium plating offer mechanical robustness and corrosion protection, while the solder cup contacts support reliable electrical connections in dynamic environments commonly found in aerospace and defense applications.
Lifecycle considerations include monitoring the cadmium plating condition and ensuring the backnut remains properly torqued to maintain panel seal integrity. The REACH-compliant materials support long-term environmental compliance, and its compatibility with standard Souriau 851 series interfaces helps simplify stock management and spares provisioning, reducing downtime and total cost of ownership over multiple programs.
