Micro BNC Connectors Guide
What Are Micro BNC Connectors?
Micro BNC connectors are a smaller version of BNC connectors. Like BNC connectors, Micro BNC connectors use bayonet locking for easy coupling, with a 75 Ω mating specification (50 Ω in some cases).
While keeping the standard BNC mating method, their compact size allows high-density mounting four times that of BNC connectors, with a minimum practical array spacing of 8 millimeters.
Micro BNC RF Connectors by Type
Micro BNC RF Connectors Features
Compact and High-Performing
The Micro BNC connector’s compact design allows high-density mounting, four times that of BNC connectors, with a minimum pitch of 8 mm. It supports 12G-SDI for high-definition and large-capacity image transmission. 4K signals can travel long distances over a single cable while maintaining stable performance even at high frequencies.
Impedance
Micro BNC connectors have a 75 Ω impedance, mainly for transmitting video and audio signals to TV receivers and other equipment. Some models are compatible with 50 Ω cables.
Coupling Method
The bayonet lock method allows easy connection without threading. Align the plug with the jack guide, rotate the ring to lock, and the internal spring holds it firmly. To remove, turn in the opposite direction; the connector cannot be pulled out by cable tension alone.
Trivia: The Origin of BNC
BNC likely comes from Bayonet Neill Concelman, the connector manufacturer. Other theories suggest it stands for Bayonet Connector, Baby-series N Connector, or British National Connector.

Micro BNC RF Connectors FAQ
QCan they be mated with mini-BNC?
QCan they be mated with mini-BNC?
No, they cannot. In size order, standard BNC is larger than mini BNC, which is larger than Micro BNC. Connectors from other manufacturers, such as Micro BNC and HD-BNC, are compatible.
QIs there an easy way to mate them in a narrow pitch area?
QIs there an easy way to mate them in a narrow pitch area?
Yes. Micro BNC connectors are miniaturized for high-density mounting in narrow pitches. Mating can be tricky, but a dedicated tool allows smooth connection.
QWhat is the purpose of the tool bit for a round nut?
QWhat is the purpose of the tool bit for a round nut?
Some Micro BNC receptacles for printed circuit boards use a round nut to clamp the enclosure. Since it is not hexagonal, the bit for round nut tool is used to tighten it.
QAre Micro BNC connectors suitable for high-density mounting?
QAre Micro BNC connectors suitable for high-density mounting?
Yes, Micro BNC connectors are designed for high-density mounting. Their compact size allows for four times the density of standard BNC connectors, with a minimum pitch of 8 mm.
QWhat is the impedance rating of Micro BNC connectors?
