The 24V 90dB SMD Piezo Buzzer is based on the principle of piezoelectric effect. It generates 90dB high sound pressure level alarm sound by driving the metal diaphragm through the telescopic vibration of the ceramic plate under the alternating electric field, this 24V 90dB SMD Piezo Buzzer is suitable for industrial equipment, security systems and other scenarios of sound and light warning needs.

Key Features of 24V 90dB SMD piezo buzzer
