With the continuous pursuit of thinness and miniaturization in products such as smartphones, tablets, drones, medical imaging equipment, and AR/VR glasses, the internal wiring space has become increasingly compact. In order to achieve stable transmission of high-frequency signals within a limited space while considering the characteristics of extreme thinness, softness, and bend resistance, extremely thin coaxial cable bundles (Micro Coaxial Cable) have gradually become the preferred choice for internal wiring in high-end electronic products. So, just how thin can extremely thin coaxial cable bundles be? What are the available wire gauges? Let's take a detailed look together.
The selection of a micrometer for extremely fine coaxial cable束
The American Wire Gauge (AWG) is commonly used to denote the wire size, with a larger number indicating a finer wire diameter. There is a rich variety of AWG sizes for ultra-fine coaxial cable assemblies, with common specifications including:
AWG32, AWG36, AWG38, AWG40, AWG42, AWG44, AWG46, AWG48. Among them, the inner conductor diameter of AWG48 is about 0.03mm, only half the thickness of a hair, which belongs to the extreme ultra-micro wire material. It is mainly used in high-precision scenarios such as ultra-small endoscopes, micro camera modules, and medical sensors.
Part two: The minimum specification of ultra-fine coaxial cable束
The minimum outer diameter of the commonly available ultra-thin 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 a wire gauge of AWG48, which can meet the high-precision application needs of ultra-micro medical equipment, endoscopes, micro camera modules, VR glasses, and other devices.
Why are ultra-fine wire bundles so important?
The wide application of ultra-fine coaxial beam is mainly due to the multiple advantages brought by its fineness:
Space-saving: The internal layout of the device is more compact.
Strong anti-interference capability: coaxial structure is superior to traditional wiring design.
Soft and flexible: suitable for bending wiring in high-density, small spaces.
High-frequency signal stability: Ensures high-definition image and high-speed data transmission.
With a rich selection of conductor sizes from AWG32 to AWG48, and the capability of the thinnest reaching 0.18mm OD, ultra-thin coaxial cables 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 the science of materials and manufacturing processes continues to advance, its ultimate values are still expected to be further refreshed.
