These versatile internal piezo buzzers from RS PRO are an adaptable and energy-efficient choice. They offer a broad voltage range, high sound output and low power consumption in a space-saving package. As they work at temperatures from -30°C and +85°C, they're suited to demanding working conditions inside or out.

Operating between 4 V dc and 28 V dc and needing only a 5 mA supply current, these buzzers produce a clear fast-pulsing 82 dB tone. Their design is compact and they can be panel mounted, so installation is straightforward. The buzzers feature flying leads, which make them easy to connect to circuit boards.

These piezo buzzer components conform to ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 electrostatic control standards and have been stringently tested as part of our RS PRO range. They have many uses, from automotive equipment to fire alarms.
