Wired Buzzer Piezoelectric Ceramic Chip Components(35mm 20PCS)

[Vibration response without external power supply]: This component generates a voltage under the effect of mechanical stress, without requiring an external power supply. This feature allows it to be used as a standalone sensor in applications where it is difficult to install power cables. [Suitable for curved surfaces]: The thin structure of the disc allows it to adapt to slightly curved or uneven surfaces. This feature is particularly useful when the sensor is to be attached to a non-planar panel or inside a complex shaped housing. [Insensitivity to Surrounding Interference]: Its principle of operation is based on mechanical deformation, and not on an external electrical phenomenon. This feature allows it to be used near transformers, motors or other equipment without suffering signal interference. [Wet Use]: The leak-proof structure of the disc prevents moisture from entering the active components. This protection allows it to be used in environments where condensation is likely to form, for example on musical instruments exposed to temperature fluctuations. [Check the fastener before use]: Before commissioning, please ensure that the disc is properly glued to the surface to be monitored. Partial contact can reduce sensitivity and generate irregular signals when detecting vibrations.
