Continuous Active Buzzer DC 3V–24V

he Continuous Active Buzzer DC 3V–24V is a versatile and reliable sound device used in alarms, indicators, and electronic circuits. Designed to operate across a wide voltage range, it produces a steady and loud audible tone as soon as DC power is applied.

Unlike passive buzzers, this is an active buzzer, meaning it has a built-in oscillation circuit and requires no external signal to generate sound. Simply connect the red wire to positive (+) and the black wire to ground (–), and the buzzer immediately produces a continuous tone.

Its compact, lightweight design makes it easy to mount on panels, devices, and circuit boards. Commonly used in DIY electronics, industrial alarms, automotive indicators, and security systems, this buzzer is a must-have for warning and notification applications.
