Connectors • BNC Connectors
A common type of RF connector used for terminating coaxial cable, A BNC connector is used in electronic test equipment and often within manufacturing facility applications. BNC connectors come in 50 ohm and 75 ohm versions. The 75 ohm BNC connectors are mainly used for video, while the 50 ohm connectors are utilized for data and RF. Types of BNC connectors include threaded, twin, and tri-axial. The tri-axial connectors are used in sensitive electronic measurement systems found in manufacturing facilities. The threaded connectors - known as TNC connectors – work well with microwave frequencies, while twin connectors contain two independent contact points.
