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

Under the trend of continuous miniaturization, portability, and high integration of electronic devices, traditional cables have long been unable to meet the extreme requirements of ultra-small electronic products in terms of space, performance, and reliability. At this time, Micro Coaxial Cable (极细同轴线) has gradually become a new favorite for internal connections in high-end electronic devices due to its excellent transmission performance and flexible cabling capabilities. Especially the extremely thin specification cables such as 40AWG (about 0.079mm) have 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 structure cable 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.
It not only achieves high-speed signal transmission but also has excellent anti-interference capability, making it very suitable for use inside electronic products with limited space but high requirements for signal quality.

The core advantages of the ultra-thin 40AWG coaxial cable
Super-micro miniaturization design
The overall diameter can be as low as 0.3mm, facilitating flexible wiring in compact spaces and helping to make the product lighter and thinner.
High-frequency and high-speed transmission capability
Supports high-speed signal transmission of up to 6~12Gbps, easily meeting 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 moving parts application environments.

With its excellent transmission performance and flexible wiring characteristics, the 40AWG ultra-thin coaxial cable is increasingly becoming the mainstream choice for internal connections in ultra-small electronic devices. Whether it's for smartphone camera modules, AR/VR devices, or miniature medical devices and robotic joint modules, these cables are indispensable for their balanced advantages in high-speed and miniaturization.
