Compact size panel mounting
Continuous tone buzzers
Screw terminal connectors

These versatile piezo buzzers offer a broad voltage range, a loud and continuous tone as well as low power consumption. As part of our tried-and-tested RS PRO series, they emit a crisp and clear sound.

The buzzers draw only an 8 mA current and operate at between 4 V DC and 28 V DC. As a result, they're very energy efficient and compatible with most consumer appliances. With a continuous 97 dB tone, they can be heard clearly from a distance – even in noisy conditions. The buzzers are simple to install, as they're simply panel mounted. Thanks to their handy screw terminals, wires can be connected to them without the need for soldering.

These are well-suited for use as alarms and warning devices, conforming to ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 electrostatic control standards. With their loud and continuous tone, these are the perfect choice for noisy offices or factory floors.
