Piezo Buzzer 10pcs/lot (18mm brass)

[Vibration response without external power]: This component generates voltage under the action of mechanical stress, without the need for external power supply. This feature makes it usable as a standalone sensor in applications where it is difficult to lay power cables. [Adaptability to 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 needs to be fixed on unflat panels or inside complex shaped enclosures. [Insensitive to environmental interference]: Its working principle is based on mechanical deformation and not external electrical phenomena. This feature allows it to be used near transformers, motors or other equipment without suffering signal interference. [Use in wet environments]: The sealed disc structure limits the ingress of moisture into the active components. This protector allows it to be used in environments where condensation is possible, for example in musical instruments exposed to temperature fluctuations. [Check for fixation before use]: Before commissioning, make sure the disc adheres correctly to the detection surface. Partial contact could reduce sensitivity and generate irregular signals during vibration detection
