BNC75Ω Type RF Connectors

Please note that you only need to register as a member for the first time.

High-frequency BNC75Ω type rf connectors are used in broadcasting and information-related equipment. We offer various connectors compatible with recent high-definition and large-capacity image transmission standards (12G-SDI, etc.). The bayonet lock method is used for easy coupling.

BNC connectors are divided into 50Ω and 75Ω. The 50Ω rf connector is mainly for transmitting electric power in radio equipment, etc., and the 75Ω rf connector primarily sends video and audio signals to TV receivers, etc.

Some BNC50Ω,BNC50Ω type RF connectors are available for purchase from Digi-Key.

Trivia: About Cables

JIS Standard
Japanese Industrial Standards (JIS) compliant cables. The higher the number of the part number, the thicker the cable. "D: 50Ω" and "C: 75Ω" represent the impedance.

The bayonet lock method is a coupling method that can be easily connected and disconnected and secured without resorting to threading or other means. Align the plug with the guide on the jack side, insert the plug, and turn the ring at the tip slightly to lock it in place, and the internal spring force will hold it firmly in place. It can be quickly removed by turning it slightly in the opposite direction, but since it is secured to the spring by a screw, it cannot be pulled out simply by pulling on the cable.

Trivia: The Origin of BNC

There is a theory that Bayonet Neill Concelman comes from Bayonet and Neill Concelman (the name of the connector manufacturer), from which the name BNC was derived. However, there are several theories as to the origin of the name, including that it simply stands for BayoNet Connector, Baby-series N Connector, and British National Connector.

BNC connectors are divided into 50Ω and 75Ω. The 50Ω type is mainly used for transmitting electric power in radio equipment, etc., while the75 Ω type is primarily used for sending video and audio signals to TV receivers, etc. When a 75Ω cable is used with a 50Ω type connector, a 75Ω transmission line can be used if the frequency is 200 MHz or lower. If the frequency exceeds 200 MHz, using BNC75Ω connectors is recommended.

The BNC75Ω connector is compatible with 12G-SDI, the recent high-definition, high-capacity image transmission standard. 4K equivalent signals can be transmitted over long distances with a single cable, and stable performance can be obtained even in high-frequency bands.
