Circular Connectors & Cables
Reliable circular connector solutions for signal, data, and power transmission across industrial and electronic applications.
What Are Circular Connectors?
Circular connectors are electrical connectors with a round interface designed for reliable signal, data, and power transmission. Their compact structure, secure locking options, and flexible installation formats make them widely used in industrial automation, transportation equipment, energy systems, and electronic devices.
Compared with many rectangular interfaces, circular connectors are often chosen for applications requiring compact installation space, vibration resistance, sealed connection, and stable electrical performance. FPIC provides circular connector and cable assembly solutions ranging from miniature signal interfaces to larger power-oriented connector sizes.
Circular Connector Series Overview
FPIC offers circular connector series covering compact signal connectors, standard industrial interfaces, and larger circular power connectors. Different sizes support different installation spaces, transmission requirements, and application environments.
Ultra-compact connectors for miniature sensors, compact devices, and limited-space applications.
Miniature threaded connectors for compact industrial equipment and instrumentation applications.
Industry-standard connectors for sensors, actuators, field wiring, and industrial communication interfaces.
Robust circular connectors for industrial drives, feedback systems, and signal or power transmission.
High-performance circular connectors for servo motors, drives, and demanding automation systems.
Large-size circular connectors designed for industrial equipment requiring larger power interfaces.
Heavy-power circular connectors for larger industrial equipment and high-current applications.
Fast-locking circular connectors for quick mating, secure retention, and efficient installation.
How to Select the Right Circular Connector
The right circular connector should be selected based on installation space, transmission requirement, locking method, and assembly structure. FPIC supports both standard selection and custom development for project-specific requirements.
