Part of our stringently tested RS PRO series, these internal buzzers are designed to be versatile. They operate at a wide voltage range and deliver crisp sound from a compact package.

The buzzers are suitable for use in many areas, including most consumer appliances, including computers and microwaves. They draw a 32 mA current, making them more reliable than lower current buzzers, and they can function between 6 V DC to 28 V DC. Their slow-pulsing 80 dB tone is audible and clear, even from some distance. Compared to magnetic buzzers, they have a lower impact on surrounding circuitry. For fast and simple installation, they come with a screw mounting.

Rigorous testing has ensured these piezo buzzers meet the ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 standards, which means they're protected from harmful electrostatic discharge. You'll find buzzers such as this in car equipment, doorbells and alarms.
