TNC RF Connectors Guide: Types, Structure, and Uses Explained
What are TNC RF Connectors?
Our TNC RF connector series is engineered for secure and reliable signal transmission in demanding radio and communication systems. Unlike the bayonet coupling of BNC, Tyclon's TNC connectors feature a robust, threaded coupling mechanism that guarantees superior performance and stable connectivity—even in high-shock and high-vibration environments commonly found in industrial applications.
Tyclon's TNC RF is offered in standard-polarity and reverse‑polarity (RP‑TNC) variants and is RoHS and REACH compliant. You can purchase directly online or contact Tyclon for assistance; technical support, datasheets, and catalogs are available.
TNC RF Connectors by Type
TNC RF Connector Features
Coupling Method
TNC utilizes a precision-threaded coupling (standard 7/16-28) to deliver superior mechanical stability and signal integrity. This design guarantees reliable performance and maximum durability against constant shock and severe vibration, making it the ideal choice for ruggedized environments.
Impedance
Our standard TNC connectors maintain a constant 50 Ω impedance, optimized for efficient power and data transmission up to 11 GHz. (For information on specialty 75 Ω interfaces, please consult our technical datasheets.)
Materials & Compliance
Tyclon connectors feature robust bodies crafted from Nickel-Plated Brass, utilizing a Gold-Plated center contact for high conductivity and excellent corrosion resistance. All standard TNC series products are RoHS and REACH compliant, ensuring suitability for export worldwide.
Variants Available
We offer a comprehensive line of standard plugs and jacks, and Reverse Polarity (RP) plugs, along with various mounting options (bulkhead, PCB, etc.) to meet any system requirement.

Micro-Coaxial Cables
Trivia: Compatible Cable Types
- MIL Standard Cables: These cables, also known as Mil-Spec, are engineered to meet rigorous US military specifications for performance and durability. They often feature the "RG" prefix, which stands for "Radio Guide," reflecting their roots in radio technology. They are critical in demanding applications like defense, aerospace, and telecommunications, where reliability is non-negotiable.
- Micro Coaxial Cables: These ultra-thin cables are designed to connect to miniature RF connectors like U.FL. They ensure signal integrity in space-constrained devices such as smartphones, laptops, and medical equipment, making them vital for modern compact electronics.
TNC RF Connector FAQs
QWhy are there so many small lots of made-to-order products?
QWhy are there so many small lots of made-to-order products?
Many TNC plugs can be assembled by replacing the coupling with a BNC 50Ω plug. Since assembly can be done in about 1W after receiving an order, there are cases where a BNC50Ω plug can be assembled if available, even if it is not available in TNC's regular products.

QWhy is BNC stamped on TNC connectors?
QWhy is BNC stamped on TNC connectors?
Some TNC connectors are stamped with BNC because they are made from the same materials as BNC connectors.
QIs there a way to make the cable assembly more inexpensive?
QIs there a way to make the cable assembly more inexpensive?
We have connectors with a crimp-type cable attachment. Although a crimping tool is required for the assembly, it is lighter and less expensive than the clamping type connectors. You do not need to purchase crimping tools if you request us to process the cable assembly.
QWhat impedance options do Tyclon TNC connectors support?
QWhat impedance options do Tyclon TNC connectors support?
TNC connectors are primarily 50 Ω for RF and microwave applications, with 75 Ω versions available for video and broadcast uses. While 50 Ω connectors can work with 75 Ω cables up to 200 MHz with minimal loss, matching impedance is recommended for optimal signal integrity.
QWhat's the difference between standard and reverse polarity (RP-TNC) connectors?
QWhat's the difference between standard and reverse polarity (RP-TNC) connectors?
Standard TNC connectors have a female contact in the jack and a male contact in the plug. RP-TNC connectors reverse this (male in jack, female in plug) to prevent mating with standard connectors commonly used in Wi-Fi and wireless networking.
QWhat materials are used in Tyclon's TNC connectors?
QWhat materials are used in Tyclon's TNC connectors?
Tyclon uses brass or stainless steel for durability and corrosion resistance, gold-plated center contacts for conductivity, and PTFE (Teflon) dielectric for low signal loss. Some TNC connectors may be adapted from BNC materials, occasionally bearing a "BNC" stamp.
QWhy is "BNC" stamped on TNC connectors?
QWhy is "BNC" stamped on TNC connectors?
Some TNC connectors are stamped with BNC because they are made from the same materials as BNC connectors.
QWhat cable types are compatible with Tyclon TNC connectors?
QWhat cable types are compatible with Tyclon TNC connectors?
