Circular Connectors

Circular connectors—also known as circular interconnects—are cylindrical, multi-pin electrical connectors designed for transmitting power, data, or signals. Their circular interface and housing allow for quick and easy mating and unmating of signal, power, and optical circuits, without the need for specialized tools such as torque wrenches.

Built to endure harsh environments, circular connectors are commonly used in demanding applications across industries such as aerospace, defense, broadcast, industrial automation, energy, medical, and transportation. They typically feature metal or composite shells with embedded contacts set in insulating materials to ensure proper alignment and reliability. The connection to cables helps resist accidental disconnection and environmental interference.

Circular connectors are available in various configurations, including:

Connector Types: Plug, receptacle, jack, line and panel connectors, T-distributors, terminal outlets, and more.

Key Specifications: Number of positions, shell size (including MIL specifications), insert arrangements, mounting styles, and fastening methods.
