In the era of continuous development towards thinness and portability of electronic products, the choice of connection cables has become a key concern for design engineers. Smartphones, wearable devices, ultra-thin laptops, and tablets, while pursuing ultimate space utilization, have also promoted the widespread application of micro coaxial cable. Among them, the 46AWG ultra-thin coaxial cable, with its miniaturized structure and excellent electrical performance, is gradually becoming the preferred solution for internal signal connection in high-end ultra-thin devices.
What is a 46AWG ultra-fine coaxial cable?
AWG (American Wire Gauge) is a commonly used standard for wire gauge in North America, where a higher number indicates a finer wire diameter. The diameter of 46AWG wire is about 0.04mm, thinner than human hair, and belongs to one of the extremely fine specifications that can be mass-produced currently. Micro coaxial cable (ultra-fine coaxial cable) is a type of precision cable that uses a coaxial structure, usually consisting of a conductor, insulation layer, shielding layer, and sheath. This structure can balance signal integrity and anti-interference performance in extremely small sizes, making it very suitable for high-speed transmission applications with limited space.
Why are ultra-thin devices more inclined to use 46AWG?
With the integration of multifunctional modules such as 5G communication, high-definition camera, OLED display, and wearable health monitoring, the number of internal connections in the device has increased dramatically. Traditional FPC (flexible printed circuit) or ribbon cables are no longer able to meet the requirements in terms of anti-interference, bending performance, and wiring density, making the 46AWG micro coaxial cable an ideal alternative solution.
Section 3: Core Advantages
Extra-fine and ultra-soft, extremely space-saving
The 46AWG wire diameter is extremely small, with a minimum bending radius that can be less than 1mm, allowing for flexible adaptation to the compact structures inside devices such as smartphones, headphones, watches, AR/VR glasses, etc., significantly improving space utilization efficiency.
Stable high-speed signal transmission
The coaxial structure positions the signal conductor at the center of the shielding layer, effectively suppressing signal attenuation and crosstalk, and is suitable for high-speed transmission scenarios such as 4K/8K camera modules and OLED screens.
Excellent anti-electromagnetic interference capability
Through the design of inner shielding plus outer copper foil or woven layer, the 46AWG cable can maintain signal integrity in complex electromagnetic environments, especially suitable for internal connections of wireless high-speed communication modules such as 5G, Wi-Fi 6, and Bluetooth.
Bend-resistant, reliable and durable
Utilizing high-performance insulating and sheath materials, it can withstand multiple bends and dynamic movements, ensuring long-term stability in wearable devices and active joint areas.
Four, Typical Applications and Development Trends
With the continuous development of electronic devices towards thinness, high speed, and integration,
46AWG and finer gauge micro coaxial cables will see broader applications in the following fields:
Wearable medical devices: used for physiological signal collection and transmission.
XR (Extended Reality) and smart glasses: used for high-speed image data links.
Vehicle intelligent terminal: used for connecting camera and sensor modules.
Flexible folding terminal: achieve high reliability interconnection between the screen and the main controller.
In the future, with the advancement of ultra-fine coaxial process and material technology, the 46AWG micro coaxial cable will become a key supporting technology for the next generation of high-density interconnection.
