112517 is a BNC bulkhead crimp jack connector designed for miniature coaxial cable applications. It features a 50 ohm impedance characteristic, nickel finish, and Delrin insulation material, with cable group 05A compatibility. The connector utilizes crimp tool type B for secure attachment and is rated for frequencies up to 4 GHz in 50 ohm applications. This bulkhead jack is commonly used in panel-mount installations where space is limited and reliable RF signal transmission is required, such as in test equipment, communications systems, and instrumentation applications.
