RS PRO 80dB Panel Mount Continuous Internal Piezo Buzzer, 42.5 x 33mm, 6V dc Min, 28V dc Max

RS PRO Panel Mount Continuous Internal Piezo Buzzer, 80 dB

If you need an alarm that's easy to mount directly to your printed circuit board (PCB), choose this piezo buzzer from RS PRO. It comes fitted with three male FASTON terminals, so you can connect it directly to your panel with no additional tools required.


This DC buzzer can generate a continuous tone of up to 80 decibels (dB) with a low current input of just 10 mA. This means it's highly audible as well as energy-efficient.

The component is safe to use around electrical and electronic equipment, as it conforms to American (ANSI/ESD S20.20:2014) and British (BS EN 61340-5-1:2007) electrostatic control standards and won't discharge static electricity. Buzzers like this are frequently used as alarms in electronic devices.
