This piezo buzzer from RS PRO is ideal for panel mounting as an alarm. It enables you to achieve a high sound output and a broad frequency range from a low-current input.
The DC buzzer is fitted with an internal drive that means it needs no additional circuitry to generate sound, making life easier for systems engineers. It will produce a pulsed sound that's ideal for attracting attention. The faston terminals allow you to connect and disconnect the buzzer quickly and easily.
The buzzer conforms to American (ANSI/ESD S20.20:2014) and British (BS EN 61340-5-1:2007) electrostatic control standards, meaning it won't damage equipment via electrostatic discharge. Buzzers of this kind are commonly used as an alert system in a wide range of electronic devices.
