40AWG ultra-fine coaxial cable: High-speed transmission power in small spaces

As electronic devices continue to develop in the trend of slimming down, portability, and high integration, traditional cables have long been unable to meet the ultimate requirements of ultra-small electronic products in terms of space, performance, and reliability. At this point, Micro Coaxial Cable (极细同轴线) has gradually become a favorite for internal connections in high-end electronic devices, thanks to its excellent transmission performance and flexible wiring capabilities. Especially the extremely thin specification of 40AWG (about 0.079mm) cables has been widely used in scenarios such as high-pixel camera modules, wearable devices, medical endoscopes, smart glasses, and ultra-thin laptops.

What is a 40AWG ultra-fine coaxial cable?
Micro Coaxial Cable is a miniature coaxial cable structure consisting of an inner conductor, insulating layer, shielding layer, and outer sheath.
The 40AWG specification indicates that the inner conductor diameter is only about 0.079mm—thinner than a hair strand.
It not only achieves high-speed signal transmission, but also has excellent anti-interference ability, making it very suitable for use inside electronic products with limited space but high requirements for signal quality.

The core advantages of a 40AWG ultra-fine coaxial cable
Ultra-micro miniaturization design
The overall diameter can be as low as 0.3mm, which facilitates flexible cabling in compact spaces and helps make the product lighter and thinner.
  High-frequency and high-speed transmission capability
Supports high-speed signal transmission of 6~12Gbps, easily meets the needs of high-speed interfaces such as 4K/8K video, USB4.0, MIPI CSI/DSI.
Excellent EMI shielding performance
The precise shielding structure effectively suppresses external electromagnetic interference, ensuring signal integrity and system stability.
 High flexibility and bendability
Can withstand multiple bending and twisting, suitable for dynamic connection and movable parts application environment.

With its excellent transmission performance and flexible wiring characteristics, the 40AWG ultra-thin coaxial cable is gradually becoming the mainstream choice for internal connection solutions in ultra-small electronic devices. Whether it is for smartphone camera modules, AR/VR devices, or miniature medical devices and robotic joint modules, these cables cannot do without their balanced advantages in terms of high-speed and miniaturization.
