In the trend of miniaturization, lightweight, and high-speed signal transmission of electronic devices, the wire, this "invisible hero," is also quietly evolving. You may not have noticed, but in your phone, drone, medical equipment, and even smart wearables, there is a coaxial cable with a diameter of only 0.2mm. So, how strong is this thin wire material? Let's find out through real data!
What is a 0.2mm ultra-fine coaxial cable?
Extremely thin coaxial cables (0.2mm) are a typical type of coaxial structure cable, consisting of a conductor, insulation layer, outer conductor, and sheath arranged concentrically. As the name implies, its outer diameter is only 0.2mm, slightly thicker than a hair strand (about 0.07mm), but it can transmit high-definition video, high-speed data, and even withstand repeated bending. It is widely used in applications that require extremely high space and weight, such as smartphone cameras, endoscopes, and drone transmission.
Secondly, look at the actual test data to see just how strong it is!
• Tensile strength: The tensile strength of a single 0.2mm coaxial cable is ≥ 25N, which means that a thin thread can lift a weight of about 2.5 kilograms, comparable to a bottle of mineral water!
Bend life: Under ±90° and 30mm bend radius conditions, it can withstand more than 100,000 bends without breaking and maintain stable signal transmission.
• Impedance stability: typical impedance of 50Ω±5Ω, differential signal rate up to 6Gbps, ensuring smooth and uninterrupted video transmission for high-definition cameras or drone image transmission.
High temperature resistance: Continuous resistance to 125℃ temperature, short-term resistance to 150℃, suitable for complex high-temperature environments.
Screening effect: High-density silver-plated copper braiding + aluminum foil shielding, screening effect ≥ 90dB, strong anti-interference, ensuring high-speed signal transmission without frame dropping.
Three, application scenarios, strength witness
0.2mm ultra-fine coaxial cables are widely used in:
Internal routing of mobile phone camera module
Drone transmission system
Medical endoscope
TWS earphone battery connection wire
This ultra-fine coaxial cable not only achieves extreme thinness but also balances high strength, long lifespan, high-speed transmission, and anti-interference capabilities. With the continuous development of the 5G, AIoT, intelligent medical, and drone industries, the application scenarios of 0.2mm ultra-fine coaxial cables will become more and more diverse. In the future, they may appear in more unexpected devices.
