Circular Connectors are a category of electrical connectors characterized by a round mating interface designed to join and disconnect circuits through a coordinated plug-and-receptacle structure. They provide a standardized mechanical and electrical connection method for transmitting power, signals, or a combination of both.

Within the broader Connectors family, circular connectors are defined by their cylindrical coupling geometry and are commonly specified by their contact arrangement and mating compatibility. They are available in multiple series and styles to support different interconnection needs while maintaining consistent alignment and secure engagement.

• Primary function: Establish a reliable, repeatable electrical interface between two assemblies.
• Connection types: Offered for power, signal, or mixed-contact interconnect requirements.
• System role: Serve as an interface component enabling modular wiring and equipment interconnection.
