Product Description
TNC Female Jack Coaxial Crimp Connector
The TNC-7459-L400 is a precision TNC female jack coaxial connector designed for terminating LMR-400 coaxial cable. Also, fits RG-8 and RG-213. Featuring a durable nickel-plated brass body, a Delrin dielectric insulator, and gold-plated beryllium copper (BeCu) contacts, this connector provides a reliable, low-loss RF connection for demanding communications and wireless applications.
The threaded TNC interface provides secure mechanical coupling and resistance to loosening from vibration, making it suitable for radio equipment, antenna feed systems, RF test setups, and professional wireless installations. Its crimp-style cable termination is designed for dependable assembly when used with compatible cable-preparation and crimping tools.
With a 50-ohm impedance and a typical frequency range of DC to 4 GHz, the TNC-7459-L400 is suited to a wide range of RF signal interconnection requirements. The gold-plated center contact helps provide reliable electrical conductivity, while the nickel-plated brass body offers durability and corrosion resistance.
