RS PRO 70 dB Panel Mount Fast Pulse Internal 33 mm Piezo Buzzer Component 6 V ac/dc Min 28V ac/dc Max

The buzzers only need a 15 mA supply current and operate between 60 V DC and 250 V DC. This makes them unlikely to malfunction when connected to higher-voltage appliances. Thanks to a slow-pulsing 70 dB tone, they're easily heard without being shrill. The panel-mount units are simple to install, measuring in at only 42.5 mm in diameter. They're fitted with FASTON terminals, which mean that wires can be crimped onto them without the need to solder.

These internal buzzers have been thoroughly tested for performance and reliability as part of our RS PRO range. They're typically used in warning devices and alarms in environments such as factories, where there's high background noise.
