This element can turn any mechanical energy into electrical energy (AC). For this reason, you can use it as a knock or tap sensor.
Description:
- Piezoelectric ceramic buzzer sheet is formed by the coated electrode material as silver-metal ceramic sheet through polarization, which is mainly circular, square, rectangular and so on. It can be bonded together with metal materials such as iron, copper, steel and nickel alloy to form parts with high strength.Main performance indicators: resonance frequency Fr, impedance R, static electro - air C0.
- Piezoelectric ceramic buzzer is a basic electronic sound device, which has the advantages of simple structure, stable performance and reliability.It is not only the core component of piezoelectric buzzer, ringing and alarm, but also increasingly used as impact signal sensor in various sensitive instruments.
