In miniature electronic devices, medical instruments, high-end camera modules, and 5G radio frequency systems, the requirements for signal transmission cables are increasingly stringent. Cables must not only have the characteristics of being thin, light, and flexible but also ensure the stable and low-loss transmission of high-speed signals. The 42AWG ultra-thin coaxial cable (Micro Coaxial Cable) is a high-performance transmission medium specifically designed to meet such high-end applications. This article will introduce you to how it achieves an "lossless channel" for electronic signals.
What is a 42AWG ultra-fine coaxial cable?
"42AWG" represents a wire gauge specification and is a way of expressing the American Wire Gauge (AWG) standard. The larger the number, the thinner the wire diameter——with a diameter of only about 0.0635mm, 42AWG is almost as fine as a hair. Micro Coaxial Cable, or extremely thin coaxial cable, consists of an inner conductor, insulation layer, shielding layer, and outer sheath, and has excellent anti-interference capabilities and signal integrity. It is widely used in internal high-density connection scenarios such as camera modules, ultrasonic probes, endoscopes, drones, and high-speed data transmission equipment.
Two, structural analysis of ultra-fine coaxial wire
A 42AWG extremely thin coaxial cable is typically composed of the following four parts:
• Inner Conductor: Made of silver-plated copper or gold-plated copper, with high conductivity and strong anti-oxidation ability.
• Dielectric Insulation: Utilize materials with low dielectric constants such as FEP, PEEK, or PFA to minimize signal attenuation to the maximum extent.
Shielding layer: Using silver-plated copper woven mesh or aluminum foil, effectively resisting external electromagnetic interference.
• Jacket: Select flexible, high-temperature resistant, and flame-retardant TPU or FEP materials to ensure long-term reliable operation of the cable.
How to achieve lossless transmission of electronic signals through a 42AWG extremely thin coaxial cable?
Low-loss insulating materials, ensuring signal purity
Using insulating materials with low dielectric constants such as FEP and PFA, which have excellent high-frequency characteristics, significantly reduces the energy loss of high-frequency signals, ensuring efficient and stable transmission.
High-density shielding structure, better anti-interference performance
The ultra-fine coaxial cable uses a silver-plated copper shielding layer with over 90% weave density, which can effectively block electromagnetic interference (EMI) in complex environments, maintaining signal integrity.
High-conductivity precision conductor, more stable transmission
The inner conductor is made of silver-plated copper wire, which combines excellent conductivity and corrosion resistance, especially suitable for high-speed digital and radio frequency signal transmission.
Multi-core micro customized solutions, flexible to adapt to space
Supports 8-core, 16-core, 32-core and other multi-core parallel custom designs, which can meet the requirements of compact space wiring while ensuring that the signals of each channel do not interfere with each other.
With its exceptional characteristics of extremely fine diameter, high flexibility, high shielding, and low loss, the 42AWG ultra-fine coaxial cable has become an ideal choice for high-speed, high-frequency signal transmission within miniature high-end electronic devices. Whether in the fields of medical imaging, RF modules, or smart terminals, it carries high-speed signals without loss with the precision of a hair.
