Telegärtner TNC Jack Flange Mount 50 Ohm Crimp/Crimp for RG-58 C/U, Nickel/Gold, 1 pc J01011A0045

In RF systems, a connector that cannot maintain a stable 50-ohm impedance under vibration or thermal stress becomes a source of signal reflection and intermittent failure. The Telegärtner J01011A0045 solves this with a TNC jack designed for permanent flange mounting and reliable crimp terminations on RG-58 C/U cable.

Who is it for

RF engineers, antenna installers, and maintenance technicians who need a threaded, weather-resistant coaxial connection on panels, enclosures, or equipment chassis. It suits test setups, radio links, and industrial RF networks where repeated mating and consistent performance are required.

Main features

• TNC series, female jack with threaded coupling for secure mating and resistance to vibration
• 50 Ohm impedance, matched to RG-58 C/U coaxial cable
• Crimp/crimp terminations for both center contact and outer conductor, providing a durable, gas-tight connection
• Flange mount with four holes for rigid panel or chassis installation
• Nickel-plated brass body and gold-plated center contact for corrosion resistance and low contact resistance
• PTFE insulator supports frequencies up to 11 GHz
• Operating temperature range from -55 °C to +155 °C
• Rated for 500 V RMS and at least 500 mating cycles

Tips

Use a proper crimp tool calibrated for the RG-58 C/U ferrule size to ensure a full 360° termination. When mounting on a panel, apply a thin layer of antioxidant compound to the flange for improved environmental sealing.
