What is a TNC Connectors ?
The TNC Connectors (Threaded Neill-Concelman) is a small threaded RF Connectors intended for high-frequency signal transmission. Paul Neill and Carl Concelman created an improved version of the BNC Connectors with a screw-type coupling mechanism instead of a bayonet lock.
This threaded design performs well in settings prone to vibration or movement, making it appropriate for industrial, military, cellular, and communication applications.
At Eteily Technologies, we provide high-quality TNC connectors and cable assemblies that are engineered for dependability, minimal loss, and secure connection in harsh RF settings.
Definition & Overview
The TNC Connectors is a 50-ohm RF connector that connects coaxial cables in RF and microwave systems. Its threaded Connector provides more mechanical stability and insulation than the BNC connector.
TNC Connectors are available in both conventional and reverse-polarity (RP-TNC) configurations, depending on the application.
Types of TNC Connectors :
TNC connectors are available in a variety of designs to meet varied installation and performance needs. Each kind is designed for a certain RF application, frequency range, and environmental conditions. The following are the most popular types of TNC Connectors and their applications:
1. Standard TNC Connector :
The Standard TNC Connectors is the most often used variant. It has a threaded coupling mechanism with a 50-ohm impedance, guaranteeing a solid connection and high signal integrity up to 11 GHz.
Applications: Include general radio frequency (RF) systems, Communication Devices, Antennas, Test Instruments, and Broadcast Equipment.
2. Reverse Polarity TNC (RP-TNC) Connector :
The gender of the central contact in a Reverse Polarity TNC Connectors is reversed. This kind is commonly used to ensure compliance with wireless communication laws and prevent unauthorized antenna alterations.
Applications: Include Wi-Fi routers, WLAN modules, Internet of Things devices, and Wireless Networking Equipment.
3. Right-Angle TNC Connector :
A Right-Angle TNC Connectors features a 90° bend between the connector body and the cable entrance point. This is useful in space-constrained setups where a straight connector would not fit adequately.
Applications: Include compact RF enclosures, Car telematics, PCB Connectors, and Interior communication systems.
4. TNC Connector with Panel Mounting :
The Panel-Mount TNC Connectors is designed for chassis or bulkhead placement and offers a secure and fixed RF link. It is commonly utilized in situations where the Connectors must stay fixed while cables are attached or detached.
Applications: Include RF Enclosures, Control Panels, Routers, and Antenna Interfaces.

5. Bulkhead TNC Connector :
Bulkhead TNC Connector allow coaxial wires to pass through panels or enclosures while providing both mechanical stability and electrical protection. They normally come with a mounting nut and washer for simple installation.
Applications: Include Outside Antennas, Instrumentation Boxes, and Communication Base Stations.
6. Crimp and Solder TNC connector :
TNC Connector are available in both crimp-type (for rapid installation) and solder-type (for high reliability) terminations. Crimp Connector are commonly utilized in field installations, whereas solder connectors are chosen for laboratory or production-level applications.
Applications: Include Custom RF Cable Assembly, Antenna Manufacture, and Test Setups.
7. Waterproof/IP-Rated TNC Connector :
These TNC Connector are sealed and supplied with O-rings or gaskets to protect against moisture, dust, and environmental pollutants. They sustain dependable Connector even in severe industrial environments.
Applications: Include outdoor antennas, marine communication, and weatherproof telecom systems.
8. PCB Mount TNC Connector :
A PCB mount TNC is intended for direct soldering to printed circuit boards, resulting in a compact and secure RF interface. It is appropriate for devices that include antennas or RF modules within.
Applications: Include wireless gateways, IoT devices, and communication boards.
