Frequently Asked Questions
Q: What sizes are included in this 10-piece piezo ceramic disc buzzer pack?
A: The pack includes piezoelectric ceramic discs in the following diameters: 12mm, 15mm, 18mm, 20mm, 27mm, 35mm, and 50mm. The exact size distribution across the 10 pieces may vary, giving you a great assortment for prototyping and testing different circuit requirements.
Q: Can these piezo discs be used as both a sounder and a vibration sensor?
A: Yes! Piezoelectric ceramic discs are inherently bidirectional. They can be driven electrically to produce sound (buzzer/sounder mode) or they can detect physical vibrations and convert them into a small electrical signal (sensor/trigger mode), making them highly versatile components for a wide range of DIY electronics projects.
Q: Are the copper wire leads already attached, or do I need to solder them myself?
A: The copper wire leads come pre-attached to each disc, so you can connect them directly to your circuit or breadboard without any additional soldering on the disc itself — saving you time during prototyping and assembly.
