Coaxial cable connector types

Coaxial cable connectors are used to connect cables to other devices and maintain the cable’s shielding.

There are two distinct connector styles – known as male and female. Male connectors have metals pin which protrude from the centre and female connectors have a recessed hole to receive the pin.

Here are some of the most common coaxial connector types and their applications:

BNC ConnectorBNC Connector


Bayonet Neil-Concelman (BNC) coaxial connectors are used for quick connection or disconnection in RF equipment, test instruments, radio, television, and video signal.

RG-11 coaxial cableTNC Connector


The Threaded Neill-Concelman (TNC) connectors are small, weatherproof products which operate up to 12GHz. They’re often used in mobile phone and RF/antenna connections.

RG-6 Coaxial CableSMB Connectors


Subminiature version B (SMB) connectors are one of the most popular RF/microwave connectors for industrial and telecommunications equipment – offering a simple snap-on coupling design for cables with uncommon connections.

7/16 DIN connector7/6 DIN Connector


The 7/16 DIN (Deutsches Institut für Normung) connector is a threaded RF connector used to connect coaxial cables.

These connectors are mainly used for applications which require water resistance, as they’re robust and durable. They’re particularly useful for base stations and broadcast communication systems.

QMA ConnectorsQMC Connectors

QMA connectors are coaxial radio frequency connectors. They maintain the shielding barrier in electrical applications and feature snap-on mechanisms. They’re ideal for industrial and communications settings.


Micro coaxial (MCX) connectorMCX Connector

Micro coaxial (MCX) connectors are ideal for environments restricted in size or space.

MCX connectors operate between DC and 6GHz in wireless, GPS, TV tuner cards, RF hardware, and digital cellular applications. These connectors also have a snap-on coupling design for easy installation


RCA ConnectorsQMC Connectors

The Radio Corporation of America (RCA) connector, also called a cinch connector, is widely used for audio and video applications.
