These versatile internal buzzers are part of our stringently tested RS PRO series. Compact in size, they operate at a wide voltage range and produce a clear sound.

These buzzers can function between 6 V DC to 28 V DC, and draw a 12 mA current, making them more reliable than lower current buzzers. They're used in a range of applications, including in most consumer appliances such as computers and microwaves. The buzzers emit a slow-pulsing 80 dB tone that's clearly audible, even from a considerable distance. What's more, they have a lower impact on surrounding circuitry compared to magnetic buzzers. Installing them is quick and simple thanks to their handy screw mounting.

Strict testing has ensured these piezo buzzers meet the ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 standards, which means they've been handled and packaged in a way that protects them from harmful electrostatic discharge. Application for these buzzers include car equipment, doorbells and fire alarms.
