What are coaxial cable connectors? What types are there?

Coaxial cable connectors are electrical connectors used to connect coaxial cables to other devices. A coaxial cable is a cable that has a center conductor that is covered by a layer of insulation and then by an outer conductor. This construction effectively reduces electromagnetic interference and provides high bandwidth, low noise signal transmission. Coaxial cable connectors are usually divided into two parts: a connector head that connects to the cable, and a connector head that connects to other equipment. They are usually made of metal and offer a high degree of precision and reliability to ensure good signal transmission. Below we will introduce several common coaxial cable connectors.BNC ConnectorsBNC connectors are a common type of coaxial cable connector, usually used for video and audio equipment. They usually consist of two connector heads and a plug in the center that can be quickly plugged and unplugged.BNC connectors are typically used for high frequency signal transmission and offer a high degree of reliability and protection against interference. Common manufacturers of BNC connectors include Amphenol and TE Connectivity, among others.SMA ConnectorsSMA connectors are high-frequency coaxial cable connectors typically used in RF applications such as radio communications and satellite communications. They are small, lightweight, and provide highly reliable signal transmission.SMA connectors typically have two different impedances, 50 ohms and 75 ohms, and therefore need to be matched for use. Common manufacturers of SMA connectors include Amphenol and TE Connectivity, among others.SMB ConnectorsSMB connectors are small coaxial cable connectors typically used in RF and microwave applications. They offer high reliability and protection against interference, and are typically used for low to medium frequency signal transmission.SMB connectors typically come in two different impedances, 50 ohms and 75 ohms, and therefore need to be mated when in use. Common manufacturers of SMB connectors include Amphenol and TE Connectivity, among others.N-Type ConnectorsN-Type connectors are a type of coaxial cable connector commonly used in microwave and RF equipment. They are typically used for high power signal transmission with high reliability and protection against interference.N-type connectors typically have two different impedances, 50 ohms and 75 ohms, and therefore need to be mated when in use. Common manufacturers of N-type connectors include Amphenol and TE Connectivity, among others.
