Key features

• Standard 27mm outer diameter brass disc
• High-sensitivity piezoelectric ceramic element
• Dual-function: acts as both sound generator and vibration sensor
• Low power consumption and high energy conversion efficiency
• Ultra-thin, lightweight, and compact design
• Wide frequency response for clear tone generation
• Easy to integrate into acoustic chambers or surface mounts
• Reliable performance for DIY electronics and commercial applications

Good to know

• Handle with care to prevent cracking the brittle ceramic coating on the disc.
• Use fine-tip, low-temperature soldering irons when attaching wires directly to the ceramic layer.
• When using as a sensor with microcontrollers, use a high-value parallel resistor (e.g., 1MΩ) to prevent high-voltage spikes.
• For optimal sound output, mount the disc inside a tuned acoustic resonant cavity.
• Avoid exposing the disc to extreme mechanical stress or temperatures exceeding maximum ratings.
