112147 is a straight crimp jack connector designed for standard coaxial cable applications. It features a nickel-plated brass shell with Teflon insulation and is rated for 75 ohm impedance, making it suitable for high-frequency signal transmission up to 2 GHz. The connector uses crimp tool type A for attachment and is part of the Connex BNC coaxial connector series, which maintains bayonet lock coupling for secure connections. This jack connector is commonly used in RF and microwave applications where reliable impedance matching and low signal loss are essential, including broadcast equipment, test instrumentation, and communication systems.
