Piezoelectric Buzzers with Oscillator Circuit
- The PB series are high-performance buzzers with a unimorph
piezoelectric ceramic element and an integral self-excitation
- They exhibit extremely low power consumption in comparison to
- They are constructed without switching contacts to ensure long
life and no electrical noise.
- Compact, yet produces high acoustic output with minimal voltage.
