TNC Waterproof Female to Female Straight RF Coaxial Connector
The TNC series product is a threaded variant of the BNC connector, distinguished by its screw-thread mating mechanism. These miniature, threaded, and waterproof units maintain a consistent 50 Ohm impedance and operate within the DC-11 GHz frequency range. There are two main types of TNC connectors: standard and reverse polarity. Typically made from die-cast and molded components, these affordable connectors are suitable for various commercial applications. Although their performance may not match that of industrial or high-quality grade products, they are widely used for antenna connections and have numerous applications in avionics, communications, and general industrial sectors. Additionally, reverse polarity and 75 Ohm versions of the TNC connector are also available.

Detailed Drawing
Features:
1. Reliable mechanical performance
Solid threaded connection: the unique threaded connection, compared with the traditional bayonet connector, the connection is more stable and reliable, not easy to loosen in the vibration environment, can effectively maintain the stability of signal transmission.
Anti-loosening design: the threaded connector has a self-locking function, which can effectively prevent the connector from accidentally loosening during use, improving the reliability and safety of the connection.
Strong durability: able to withstand multiple plugging and unplugging operations, general TNC connectors can withstand at least 500 times of plugging and unplugging without damage, suitable for applications that require frequent connection and disconnection.
2. Excellent waterproof performance
Sealing structure: the connector part adopts special sealing structure, such as O-ring, which can effectively prevent moisture, dust and other external substances from entering the connector, and protect the connection point from damage.
High waterproof grade: usually with high waterproof grade, it can work stably in harsh outdoor environments or humid conditions to ensure that the signal transmission is not affected by moisture.
Application:
Industrial automation field
Connection between sensors and controllers: In industrial automation control systems, various sensors (such as temperature sensors, pressure sensors, position sensors, etc.) need to transmit the collected physical signals to the controller for processing and analysis.TNC adapters can connect the cables between the sensors and controllers to realize the accurate transmission of the data, so as to enable the controllers to accurately control the industrial equipment based on the signals from the sensors. The TNC adapter connects the cable between the sensor and the controller for accurate data transmission, enabling the controller to control industrial equipment precisely according to the sensor signals.
Connection between actuator and control system: Similarly, in industrial automation, actuators (e.g. motors, valves, cylinders, etc.) need to receive commands from the control system and execute the corresponding actions. tnc adapters can be used to connect the cables between the actuator and the control system, to ensure that the control commands are accurately transmitted, and to ensure that the industrial production process is carried out smoothly.
