BNC Connector - What Is It Meant For?


!±8± BNC Connector - What Is It Meant For?

BNC connector is a radio frequency spectrum and can be adapted as a power line to join electronic tools. There are several versions of BNC connectors in the market at this time. Some of them are TNC and triaxial connectors to name a few.

The BNC connector also known as Bayonet Neill-Concelman or is a Radio Frequency spectrum (RF) connector adapted as coaxial wire, is bascially adapted to connect a television or a radio and other radio-amplitude electronic equipment. It is adapted in frequencies which are below 3 Ghz. The connector is used for RF signal connections. It is an option to the RCA connector when used for composite video on mainstream video devices, although large consumer electronic devices with RCA jacks are usually used with BNC-only video appliances via simple adapter. BNC connectors are commonly used on 10base2 thin Ethernet networks, both on chain interactions and network cards. The TNC (threaded) connector is mostly adapted for standard performances at higher frequencies than adapted with the BNC connector.

The name of the connector is derived from the collaboration of two things. They are listed as below:

1)The connecting mechanics that has been employed behind the working of the connector
2)The names of the two inventors of the device. Those two inventors were Carl Concelman and Paul Neill, both of whom worked in the Bell Labs. Their main purpose was to develop a connector that used the principle of bayonet mount mechanism for locking.

The connector was a practical experiment, based on the research of Octavio M. Salati. Neill and Concelman perfected an earlier design and created a connector that has been adapted in several applications over the last several decades. It has been organized to process both the serial digital inter-face and the analog video broadcast. It is also capable of audio-interface managing transmissions.

As mentioned before the BNC connector is used for RF signal connections, in digital and analog video broadcast. Apart from that, it is useful for aviation electronics, amateur radio antenna connections and other types of electronic test devices and so on. They exist in 50 and 75 ohm versions. During its early days, all the connectors were 50 ohm and were joined together with different cables and the differences in the wires were not very noticeable at a lower amplitude. The newer ones, i.e., the 75 ohm category may be recognized by the absent or the reduced dielectric in the mating ends. The different wires can be mated with each other, although the differences may lead to signal reflections. The 75 ohm connectors are mostly used for DS3 Telco central office applications and are also used in video and 50 ohm is used for RF and data.

There are different types of connectors which are similar to BNC connector. They are briefly listed as follows:

A miniature version of BNC, known as TNC is also available in the market. It is superior to BNC and at microwave frequencies
Triaxial BNC connector, which was mostly adapted in NIM electronics. These have been replaced by LEMO connectors which permit higher density.
In USSR, the connectors were replicated as SR-75 which is Russian:-75 and SR-50 which is Russian: -50.
