RS PRO 88 dB Panel Mount Continuous, Fast Pulse Internal 33 mm Piezo Buzzer Component 6 V dc Min 28V dc Max

They can operate between 6 V dc and 28 V dc and only require a 16 mA supply current. This means they're compatible with most consumer appliances as well as being energy efficient. They produce a continuous and fast-pulsing 88 dB tone that can be clearly heard. As they don't use magnets or coils to create the sound, they have virtually no impact on surrounding circuitry. These space-saving piezo buzzer components are panel-mounted and simple to install.

The buzzers meet ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 standards, meaning they're handled in a way that protects them from electrostatic discharge. You'll find them used in applications ranging from doorbells to fire alarms.
