12V Electromagnetic Active Buzzer PCB Mount Type

12V Electromagnetic Active Buzzer PCB Mount Type

The 12V Electromagnetic Active Buzzer is a compact and efficient sound-generating device designed for direct DC operation. It produces an audible tone or alarm signal when powered with a 12V DC supply — no external driving circuitry required. Ideal for embedded systems, alarm circuits, and industrial control boards, this buzzer offers reliable performance and easy integration.

This active buzzer has a built-in oscillation circuit, which allows it to generate sound automatically upon receiving a DC voltage. Unlike passive buzzers, it doesn’t require an external pulse signal or microcontroller output — simply connect it to a 12V DC source, and it produces a continuous tone.

With its PCB mount pins, the buzzer can be easily soldered directly onto circuit boards, ensuring secure mechanical fit and electrical connectivity. It is widely used for audible indicators, alarms, and notification systems in both consumer and industrial applications.
