248-1489-015 is a shielded coaxial contact assembly designed for Size 12 connectors in 71C15 layout configurations. This contact is engineered to accommodate RG-179B/U cable with precise dimensional specifications including a minimum cable diameter of 0.122 inches (3.10 mm) and maximum of 0.158 inches (4.01 mm). The assembly features a ferrule body with inner pin contact, insulator, and outer conductor configuration, with critical dimensions such as a 0.187 ± 0.002 inch (4.74 ± 0.05 mm) ferrule diameter and 0.616 ± 0.005 inch (15.64 ± 0.13 mm) body length for pin configuration. These shielded contacts are utilized in receptacle connectors with 71C15 inserts and are terminated using M22520/5-01 outer and M22520/2-01 inner crimp tools, with extraction performed using CIET-12 tools. Applications include aerospace, defense, and industrial interconnect systems requiring reliable shielded signal transmission in harsh environments.
