BNC connectors are used as terminating points in coaxial BNC cable assemblies. Paul Neill and Carl Concelman were the two inventors that invented the BNC Cable . Since the connector uses a ‘Bayonet’ locking mechanism, it is called the “Bayonet Neill Concelman” or BNC connector. It is also referred to by different nicknames over the years. “Bayonet Nut Connector”, “British Naval Connector” and “Baby Neill-Concelman” are some of the nicknames given to the BNC Cable.

Neill, the inventor of the N connector was from Bell Labs. Concelman, the inventor of the C connector was an engineer from Amphenol. The BNC connected device which is used in BNC cable assemblies is a kind of RF connector which is much smaller than the individual N type and C type connectors. In fact, it was originally designed along the lines of the Type C connector in a miniature form. There are different types of bayonet connected device which use the similar twist-on attachment mechanism used in an actual bayonet. The BNC is among the larger class of bayonet connected device.

BNC connected device are widely used in a large variety of electronic equipment. Cables used in professional video equipment have BNC connectors. These are used for both analog and serial digital interface signals. BNC cable assemblies used in amateur radio antennas make wide use of BNC connected device. Moreover, almost every single piece of equipment used for electronic testing over the past 35 years make major use of the BNC connected device.

The BNC is an alternative to the RCA connector when it comes to commercial video equipment for composite video. The Radio Corporation of America introduced the design of the RCA connector during the early 1940s. These connect device were used in cables that carried video and audio signals to electronic equipment. The RCA was basically designed to connect mono phonograph players to amplifiers. It is therefore sometimes referred to as a phono connector or a cinch connect device.

Many people use RCA equipped consumer electronics devices with BNC jacks through an adaptor. 10base2 thin Ethernet networks made extensive use of BNC cable assemblies for interconnecting cables and network cards. However, since most new Ethernet devices no longer use coaxial cables, the use of BNC connectors in Ethernet networks has greatly diminished. A threaded version of the BNC connector is called the Threaded Neill-Concelman or TNC connector. The TNC connector offers superior performance at microwave frequencies when compared to BNC connectors.

BNC connectors come in 50 ohm and 75 ohm versions. They can then be used with BNC cable assemblies of the same characteristic impedance.

Design of a BNC Cable

The design of a BNC cable is an important factor which governs the quality of signal being transferred through a BNC cable. Basically, the BNC cable is commonly used as a RF connector that is employed in radios, television and radio frequency electronic components. It has also been used in some earlier computer networks, because of its high reliability and ability transfer data without any errors. Known as the Bayonet Neill-Concelman connector, there are two major types of BNC cables that are used in applications around the world today. We would be looking at these applications and types of BNC cables, and would be exploring the major difference between these BNC cables.

Types of BNC Cable Connector

There are two main types of BNC cable connector, and both have different functions and use. You would find that using one instead of the other can lead to problems with your equipment and communication. The first type of BNC cable is known as the 50 ohm BNC cable. The 50 ohm BNC cable is mainly used for applications which require an exchange of data and RF communication. The second type of BNC cable is known as the 75 ohm BNC cable. The 75 ohm BNC cable is mainly used for carrying out video transfer and is mainly used in transferring video, popularly known as cable television. These are the two major types of BNC cable connector and the applications in which they are majorly used. Apart from this, there is another concept of male and female BNC cable connectors.

BNC to RCA Cable Converter

Since the RCA cable has been in use since a long time, you might require a BNC to RCA cable converter for utilizing the new standard. The RCA cable, or Radio Corporation of America cable, is popularly used in various audio video applications where there is a transfer of images and sound. Basically, the RCA cable is a combination of 3 different cables, all color coded for information. Read the rest of this entry »
