Circular Connectors & Cable ConnectorsCircular connectors and cable connectors are types of connectors that are used to connect a cable or other type of wire to a device or circuit. Circular connectors are cylindrical in shape and have a series of metal contact pins or sockets on the inside of the connector that are used to make electrical connections with the wires in the cable. Cable connectors, on the other hand, are typically smaller and more compact, and they are designed to be attached directly to the end of a cable. Both types of connectors are commonly used in a wide range of applications, including industrial machinery, telecommunications equipment, and consumer electronics.
