BNC Connectors profile

4 11 2011

BNC connectors are an essential electronic component. They can be used within radio, television and radio-frequency equipment. They are also commonly used for signal connections.

What is a BNC Connector?

A BNC connector is a common RF (radio frequency) connector. BNC stands for Bayonet Neill-Concelman and is named after its creators and the bayonet locking mechanism it uses.

How do they work?

BNC connectors work at radio frequencies, hence why they are an RF connector. They operate in the megahertz range and are typically used with coaxial cables – leads which are commonly used to connect televisions and other such equipment.

Their operation allows them to provide a more stable transmission and reduces impedance. They are therefore an essential electronic component for the household.

BNC connectors have a number of uses in both homes and businesses. Their most common uses include:

• The connection of test equipment.

• Signal connections for aviation electronics.

• Signal connections for radio antenna.

•Video signal connection: both analogue and serial digital interface signals.

What types are available?

You can usually find a selection of two types of ohm rating: either 50 or 75ohm. The 50ohm variety is aimed at 4GHz frequencies and the 75ohm at 2GHz ones.

The different types of BNC connector are typically compatible with one another, reflecting their original design. However, at frequencies below 10MHz negative effects can be caused and signal reflections can occur at frequencies higher than this.
