Circular connectors refer to a wide range of electrical connectors where the plugs and jacks both have circular geometries. There are a wide range of allowable pin counts within the connector depending on current and voltage requirements. Often there is a notch or groove in the connector that allows for an easy alignment between each half, which prevents the pins from being damaged or bent. They are common in both metal and plastic form. The locking mechanism can be a clip, twist lock or threaded fastener to ensure proper connection.

These are commonly used in rugged applications since there are no edges to be damaged or to do damage to another component. It is also much easier to seal off a circular ring from the effect of environmental elements than other shapes. Often, if space is an issue, the circular connectors are not ideal as they cannot be stacked efficiently.
