Wired Buzzer Piezoelectric ceramic chip components (20 mm, 20 pieces)

Vibration evaluation without external power supply: The component generates a voltage under mechanical stress without the need for an external power source. Thanks to this feature, it can be used as a self-sufficient sensor in applications where the laying of power supply cables is difficult. [Adapt to curved surfaces]: Thanks to its flat design, the disc adapts well to slightly curved or irregular surfaces. This feature is particularly useful when the sensor needs to be mounted on non-flat surfaces or in complex shaped housings. Resistant to interference from the environment: The operating principle is based on mechanical deformation and not on external electrical phenomena. Thanks to this feature, the sensor can be used near transformers, motors or other devices without signal interference. Use in humid environments: The sealed design of the disc prevents moisture from entering the active elements. Thanks to this protection, the sensor can be used in environments where condensation can occur, such as musical instruments that are exposed to temperature fluctuations. [Check the attachment before using]: Before commissioning, make sure the disc rests correctly on the surface to be monitored. Partial contact can reduce sensitivity and cause irregular signals when detecting vibration.
