Micro coaxial cable is widely used in high-frequency and high-density integration fields. The shielding layer (usually a woven layer or aluminum foil) effectively suppresses electromagnetic interference (EMI), has low signal attenuation, and is suitable for high-frequency (GHz level) and high-speed data transmission. The impedance is usually 50 Ω or 75 Ω, matched with standard communication protocols to reduce signal reflection and improve transmission stability. It is widely used in medical Endoscope/catheter, AR/VR devices, Car camera/radar, Industrial robots, etc.
