    About this item

    • Buzzer Type: electric piezoelectric buzzer, sound type: continuous sound, volume: 85 to 95 decibels, working voltage: DC 3-24V.
    • High-Quality Materials: mainly composed of multivibrator, piezoelectric buzzer chip, impedance matching unit, resonator and shell.
    • Continuous Buzzer: When the rated power is connected, the impedance matching device drives the piezoelectric buzzer to sound, and the buzzer will keep beeping. Can be easily controlled.
    • Sound Pressure Level: 85 to 95 decibels, rated voltage: 12VDC, operating voltage range: 3V-24V, maximum current: 10mA.
    • Wide Application: The buzzer is an electronic sounder with an integrated structure. Using DC power supply, it is widely used in electronic products such as computers, printers, copiers, electronic toys, automotive electronic equipment, telephones, timers and so on.
