Ficha TNC Telegärtner Crimp G37 50 Ohm reta Professional (J01010A0049)

For RF engineers and installers terminating 50-ohm coaxial cables with a 7.25 mm dielectric and 2.7 mm inner conductor, the Telegärtner TNC plug provides a secure, low-loss connection. This straight cable-mount connector uses crimp termination for both center and outer conductors, ensuring repeatable assembly in field or bench environments. The Professional series design supports frequencies up to 11 GHz, making it suitable for test setups, antenna feeds, and industrial RF links where a threaded coupling is preferred for vibration resistance.

Key specifications

• Connector type: TNC plug (male)
• Impedance: 50 Ohm

Why choose it

The crimp/crimp design eliminates soldering, speeding up assembly while maintaining consistent electrical performance. Gold-plated contacts resist corrosion, and the nickel-plated brass body offers durability in demanding environments. The threaded TNC interface provides a positive lock, reducing accidental disconnection under vibration.

Ideal use cases

• Terminating RG-58-type or similar 50-ohm cables in RF test and measurement
• Antenna feed lines for mobile or fixed installations
• Industrial RF equipment requiring threaded connectors
• Field repairs and custom cable assemblies

Good to know

This connector is supplied as a single piece. It is suitable for cables with the specified dielectric and inner conductor diameters; verify your cable dimensions before ordering. Crimp tools and dies for the G37 group are required for proper termination.
