Circular Connectors

In demanding fields such as industrial automation, aerospace, medical devices, test and measurement, and military applications – where connection performance, stability, and environmental adaptability are paramount – circular connectors stand as indispensable core components. More than just simple plugs and receptacles, they are the critical guarantors for reliable signal, data, and power transmission within complex systems. Our comprehensive range of circular connectors is specifically designed to withstand harsh environmental challenges, ensuring your equipment operates continuously and efficiently under any working conditions.

We understand your absolute pursuit of connector reliability. Our circular connector product line offers unparalleled connectivity solutions, built upon the following core advantages:

• Exceptional Mechanical & Environmental Protection: The robust shell design of circular connectors provides outstanding resistance to vibration and shock. Coupled with precise sealing technologies, such as various IP ratings, they effectively guard against ingress from dust, moisture, liquids, and even corrosive substances. This ensures stable operation in severe industrial or outdoor environments. Whether you need waterproof circular connectors or dust-proof circular connectors, our solutions meet your most stringent requirements.
• High Density & Multi-Functional Integration: The compact circular layout ingeniously integrates multiple pins or sockets, sometimes hundreds, allowing for high-density connections within limited space. This capability enables our circular connectors to transmit various signal types simultaneously, including power, high-speed data (such as Ethernet), RF signals, and even fiber optics. This significantly simplifies wiring and enhances system integration.
• Fast, Convenient, and Secure Locking Mechanisms: Catering to diverse application scenarios, we offer a variety of fastening types and locking mechanisms, including classic threaded connectors, user-friendly bayonet connectors, and efficient push-pull connectors. These mechanisms ensure connections are secure and resistant to accidental disconnection, while also supporting quick connect/disconnect operations, greatly improving the efficiency of installation, maintenance, and troubleshooting.
• Extensive Customization & Standardized Compatibility: From miniature to large, and from standard to custom designs, our circular connector series covers a wide range of shell sizes and contact arrangements (number of positions). We strictly adhere to industry standards, such as MIL-DTL series military specifications and M-series industrial standards (e.g., M8, M12, M23), ensuring seamless compatibility with existing systems. We are also adept at providing customized solutions to meet your specific application needs.
• Versatile Application Spectrum: Our circular connectors are widely adopted across numerous industries, including:
  • Industrial Automation: Sensors, actuators, industrial cameras, robotics control systems.
  • Transportation: Rail systems, new energy vehicles, marine electronics.
  • Medical Devices: Diagnostic equipment, patient monitors, surgical instruments.
  • Aerospace & Military: Avionics, communication systems, ground support equipment.
  • Test & Measurement: Precision instruments, data acquisition devices.
  • Outdoor & Harsh Environments: Outdoor LED displays, base station equipment, mining machinery.

Choosing the right circular connector means opting for stability, efficiency, and long-term reliability. When making your selection, be sure to consider the connector type, number of pins, shell size, mounting type (e.g., panel mount, cable mount), and fastening type to ensure perfect compatibility with your system.
