H・BNC Type RF Connectors

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

H・BNC type rf connectors are a smaller standard of BNC type rf connectors. They are compatible with connectors such as MICRO BNC and HD-BNC. Like BNC connectors, H・BNC connectors use the bayonet locking method for easy coupling, and the mating part is 75 Ω specification (50 Ω specification in some cases).

While maintaining the standard mating method of BNC type rf connectors, the compact size allows high-density mounting four times that of BNC connectors, and the minimum density practical limitation is 8mm when applied to an array.


No cables with H・BNC connectors are available in stock.

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 compact appearance of the H・BNC connector allows for high-density mounting, four times that of BNC connectors, with a minimum pitch of 8 mm. It is also compatible with 12G-SDI, the current standard for high-definition and large-capacity image transmission. 4K equivalent signals can be transmitted over long distances with a single cable, and stable electrical characteristics can be obtained even in high-frequency bands.

H・BNC connectors have an impedance of 75 Ω and are mainly used to transmit video and audio signals for TV receivers and other equipment. Some connectors can be coupled with 50Ω 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.
