With the continuous pursuit of slimming and miniaturization in products such as smartphones, tablets, drones, medical imaging equipment, and AR/VR glasses, the internal wiring space becomes increasingly compact. In order to achieve stable transmission of high-frequency signals within limited space while taking into account the characteristics of extreme thinness, softness, and flexibility, ultra-fine coaxial cable (Micro Coaxial Cable) has gradually become the preferred choice for internal wiring in high-end electronic products. So, how thin can ultra-fine coaxial cable be? What are the available wire gauges? Let's take a detailed look together.
Selecting wire gauges for extremely fine coaxial cable束
The American Wire Gauge (AWG) is commonly used to indicate the wire size, with larger numbers representing finer wire diameters. There is a rich variety of wire gauges for extremely fine coaxial cable assemblies, with common specifications including:
AWG32, AWG36, AWG38, AWG40, AWG42, AWG44, AWG46, AWG48. Among them, the conductor diameter of AWG48 is about 0.03mm, which is only half the thickness of a hair strand, and belongs to the extreme ultra-micro wire material. It is mainly applied in high-precision scenarios such as ultra-small endoscopes, micro camera modules, and medical sensors.
Second, the minimum specification of extremely thin coaxial cable束
The minimum outer diameter of the conventional ultra-fine coaxial cable bundles on the market can reach 0.20mm OD (corresponding to AWG46). Some high-end customized models have broken through to 0.18mm OD, with wire gauge reaching AWG48, which can meet the high-precision application requirements of ultra-micro medical devices, endoscopes, micro camera modules, VR glasses, and other applications.
Why are extremely fine bundles of wire so important?
The extensive application of extremely thin coaxial cables is mainly due to the multiple advantages brought by their thinness:
Space-saving: The internal layout of the device is more compact.
Strong anti-interference ability: coaxial structure is superior to traditional wiring design.
Soft and flexible: suitable for bending wiring in high-density, small spaces.
High-frequency signal stability: Ensuring high-definition images and high-speed data transmission.
With a rich selection of wire gauges ranging from AWG32 to AWG48, and the ability to achieve the thinnest 0.18mm OD, ultra-fine coaxial cable assemblies have become the mainstream solution for high-frequency transmission in modern high-end consumer electronics, medical equipment, security modules, and other industries. In the future, as material science and manufacturing processes continue to advance, its ultimate values are still expected to be further refreshed.
