Coaxial Cable Connector Types and Their Importance

Coaxial cables are one of the most common cable types, supporting the transfer of data and signals for cable television, radar, radio frequency (RF), instrumentation, communication, and military applications alike. While signals travel from one system to another through lengths of wire or cables, all connections between conducting components are made through the use of coaxial cable parts. Capable of providing for reliable connections and shielding maintenance, it can be highly beneficial to have a general understanding of coaxial cable connectors. In this blog, we will discuss the role of such components in brief detail, as well as the most common types that are available on the market.

Just like many other forms of cable connectors, coaxial cable connectors are designed to top and tail cables, connect cables to one another, and establish connections between devices and external power supplies. As various coaxial cables may vary in their design, numerous connectors are available to account for different sizes and dimensions. Additionally, some may even exhibit special features such as internal switches to increase their versatility and capabilities. With a basic understanding of the role of a coaxial cable connector, one should then become familiar with the most common options.

The BNC coaxial connector is a useful option for RF applications, and it ranges from miniature to subminiature types. While originally designed for military use, the BNC coaxial connector now finds common implementation within RF equipment, test instruments, video applications, and much more. With two bayonet lugs, a BNC connector can mate with a correlating component for frequencies below 4 GHz.

The Threaded Neil-Concelman (TNC) coaxial connector is simply a threaded version of the BNC connector, allowing it to perform more optimally with microwave frequencies. Capable of handling frequencies upwards of 12 GHz, TNC connector components also provide weather-proofing and a compact design that promotes easy installation in certain environments.

The SMA coaxial cable connector is a very common choice for RF applications, and it establishes connections with a screw-type coupling mechanism. While SMA connectors originally accommodate DC signals upwards of 12 GHz, variants have come about with abilities to undertake signals up to 26.5 GHz. As of the present, SMA coaxial cable connector parts are found within microwave systems, WiFi antenna systems, mobile telephone antennas, and more.

The QMA connector is a common variant of the SMA connector, featuring quick-lock and quick-disconnect features for an ease of coupling. QMA connector parts are also known for their high performance for RF signals, making them a common choice for industrial and communication applications alike. SMB connectors are another variation of SMA connectors, serving as a smaller assembly with high electrical performance. With their ease of installation and use, SMB connectors are now one of the most popular choices for industrial and telecommunications equipment.

Alongside such examples, there are also DIN connectors, MCX connectors, RCA connectors, and other various types available.
