Description Active Buzzer 3-24V Intermittent - SFM-27

The Active Buzzer 3-24V Intermittent - SFM-27 is an intermittent buzzer that emits a pulsating sound signal as soon as it is connected to power. In contrast to a continuous buzzer, this version generates short, repeated beeps. This makes it ideal for applications where attention or warning is particularly noticeable, such as in alarm systems, detectors and machines.

The buzzer operates within a wide voltage range of 3 to 24 volts. Thanks to the built-in oscillator, external control is not required. The buzzer automatically activates the interrupted sound pattern as soon as it receives voltage. The closed housing protects against dust and splash water, which increases reliability and service life.

With its compact diameter of 27 mm, this buzzer fits into small spaces without sacrificing volume. At 12V it produces a clear, audible sound of approximately 85 dB. The intermittent tone attracts attention more quickly than a constant tone, making this buzzer perfect for signaling in busy or noisy environments.

Whether you're building a warning system or developing a smart electronics project, this intermittent buzzer provides immediate results with minimal installation.
