Buzzer with Built-in Electronics 3-24 Vdc – 95dB

This buzzer with built-in electronics uses piezoelectric technology to produce high-intensity sound, with a sound pressure level of 95 dB, which makes it suitable wherever a clearly audible acoustic alarm is needed. It is designed to work at a nominal voltage of 12Vdc, but it can operate over a wider voltage range, including voltages between 3V and 24V.

The maximum current this buzzer can draw is 10mA, which keeps power consumption relatively low. The frequency of the sound emitted is about 3900Hz, with a tolerance of ±500Hz. These features make it suitable for a range of applications, such as security alarms, audible indicators and signalling in industrial and domestic settings.
