Circular Connectors

Circular connectors are made of multi-pin interconnects paired with cylindrical housing containing a contact interface. They can be made of plastic, metal, or a combination of both. Like most kinds of electrical connectors, their function is to enable a secure signal and current transmission by pairing a male half (the pins) to a female receptacle (the housing).

What are the benefits of circular connectors?

Circular connectors have increasingly been used in electronics due to their advantages over their rectangular counterparts. Because of their structure, one of their immediate benefits is the fact they can group several contacts in a compact space, enabling a space-saving and simple solution to disconnect and reconnect cables from their devices. However, they are also particularly convenient for:

  • Housing different kinds of contacts
  • Allowing contacts with different currents thanks to the extensive range of allowable voltages
  • Sealing hermetically where an absolute integer connection is needed
  • Conveying a strong mechanical performance in environmentally demanding applications

What are circular connectors used for?

Depending on their design and layout (threaded, push-pull, as well as many otherS), their use might be more suitable to certain applications rather than others, but in general the advantages brought by a circular connector make their range of applications very broad, from data and communication to military and aerospace industries. The high performance required by harsh industrial environments makes it necessary for the circular connector to be rugged and shielded against EMI to avoid any damage from water contamination, dirt, extreme temperature or vibration.
