In the era of continuous development towards thinness and portability of electronic products, the choice of connection cables has become a key focus for design engineers. Smartphones, wearable devices, ultra-thin laptops, and tablets, while pursuing the ultimate utilization of space, have also promoted the widespread application of micro coaxial cable. Among them, the 46AWG micro coaxial cable, with its miniaturized structure and excellent electrical performance, is gradually becoming the preferred solution for internal signal connections in high-end ultra-thin devices.
What is 46AWG ultra-fine coaxial cable?
AWG (American Wire Gauge) is a commonly used standard for wire size in North America, with the larger the number, the thinner the wire diameter. The diameter of 46AWG wire is about 0.04mm, which is finer than human hair and belongs to one of the thinnest specifications that can be mass-produced currently. Micro coaxial cable (ultra-fine coaxial cable) is a type of precision cable using a coaxial structure, usually consisting of conductor, insulation layer, shielding layer, and jacket. This structure can balance signal integrity and anti-interference performance under extremely small dimensions, 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 video, OLED display, and wearable health monitoring, the number of internal connections of the device has sharply increased. Traditional FPC (Flexible Printed Circuit) or ribbon cables are no longer able to meet the requirements in terms of anti-interference, bendability, and wiring density, making the 46AWG micro coaxial cable an ideal alternative solution.
Three, core advantages
Extra-fine and ultra-soft, maximizing space-saving
The 46AWG wire diameter is extremely small, with the minimum bending radius capable of being less than 1mm, allowing for flexible adaptation to the compact structures inside devices such as smartphones, headphones, watches, AR/VR glasses, and significantly enhancing space utilization efficiency.
• Stable high-speed signal transmission
The coaxial structure places 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, 46AWG cables 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 wider 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.
Car intelligent terminal: Used for connecting camera and sensor modules;
Flexible folding terminal: achieve high reliability interconnection between screen and main control.
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.
