BNC50Ω Type RF Connectors

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

BNC (Bayonet Neill Concelman)50Ω type rf connectors are widely used in video, communication, and measurement equipment because of their relatively good frequency characteristics (DC to 2GHz), small size, and lightweight. They have an impedance of 50Ω and use the bayonet locking method for easy coupling.

BNC type rf connectors are divided into 50Ω and 75Ω. The 50Ω rf connector is mainly used for the transmission of electric power in radio equipment, etc., while the 75Ω rf connector is mainly used for the transmission of video and audio signals in TV receivers, etc.

Some BNC50Ω,BNC75Ω 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.
MIL Standard
Compliant with US military standards for cables. Begins with the initials "RG" and is also called Mil-Spec.
Micro Coaxial Cables
Micro coaxial cables for attaching to miniature RF connectors such as U.FL.
Semi-flexible
Shape memory coaxial cables can be bent to a certain degree but have high shielding and low loss (attenuation).
Semi-rigid
A coaxial cable that uses a seamless metal tube to achieve higher shielding and less attenuation than semi-flexible cables.

The Bayonet lock method is an easy connection method that does not rely on threading and can be easily connected and disconnected.
Insert the plug into the jack by aligning it with the guide on the jack side, and rotate the ring 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.

Because of its low cost, good frequency response, and small size, it is the most common and versatile of all coaxial connectors. They are used in various applications, including measurement, communication, computer for video signals, office equipment, communication equipment (terminals and mobile devices), measuring equipment, audio-visual equipment, home appliances, and factory automation equipment. They are sometimes used as enhanced versions of RCA terminals (pin terminals) for simple electrical signal transmission and reception.

BNC connectors are divided into 50Ω and 75Ω. The 50Ω type is mainly used for transmitting electric power in radio equipment, etc., while the 75Ω 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 200MHz or lower. If the frequency exceeds 200MHz, using BNC 75Ω connectors is recommended.
