Depending on the design, circular connectors are made of plastic or metal and are equipped with one or two shields. They can be waterproof and meet the IP-67 degree of protection or dustproof and meet the IP-40 degree of protection. Better known circular connectors used in communication technology are the M connectors M8, M12, M23, M25 and 7/8".

Circular connectors ensure secure connections and are suitable for load currents of several amperes (A).
