Product description
Active piezo buzzer with PCB pins. The buzzer features a built-in oscillator and produces sound as soon as a DC voltage is applied. It therefore requires no external signal generator or PWM drive, making it suitable for audible indication in alarms, instruments, and other electronic applications.
At a supply voltage of 12 V, the buzzer produces a sound output of at least 90 dB measured at a distance of 10 cm. The nominal frequency is 2.4 kHz.
