What is a Connector for Ultra-Fine Coaxial Cable?

A connector for ultra-fine coaxial cable is designed to terminate and connect extremely thin coaxial cables used in compact electronic devices. These cables, commonly known as micro coaxial cables, feature a true coaxial structure despite being as thin as a strand of hair.

Example: AWG #46 with an outer diameter of just 0.2 mm (comparable to a human hair, which is approximately 0.1 mm thick).

Thanks to its coaxial design, this type of cable offers:

  • Excellent transmission characteristics
  • Superior flexibility
  • Outstanding resistance to bending and twisting

Why Use Ultra-Fine Coaxial Cables?

Ultra-fine coaxial cables are often used to connect the core components of a device—for example, the image sensor of a camera.

They are ideal for applications requiring:

  • Miniaturization
  • High-resolution signal transmission
  • Durability in tight or high-motion areas

Their excellent electrical performance and mechanical flexibility make them perfect for wiring in compact spaces or in environments where repeated bending occurs.

Example: Connecting the main board to the image sensor board in a digital video camera (DVC).

Where Are Connectors for Ultra-Fine Coaxial Cables Used?

These connectors are commonly found in compact, high-performance devices that require high-speed signal transmission, such as:

  • Digital cameras
  • DVCs (Digital Video Cameras)
  • Surveillance cameras
  • Car audio systems
  • Ultrasonic diagnostic equipment
  • Endoscopes
