RS PRO 92 dB, Panel Mount Continuous Internal Buzzer Emit sounds from your electronic equipment simply and safely with this piezo buzzer from RS PRO. It can easily be wired up to generate a continuous tone of up to 92 dB. This buzzer's internal circuitry allows it to be fitted directly onto a printed circuit board (PCB). It boasts flying leads for quick connections, while its ABS (acrylonitrile butadiene styrene) outer construction makes it very resistant to shock and chemicals. This piezo buzzer generates sounds with a much larger pressure level in comparison to magnetic buzzers. It can also operate with a relatively low current of 12 mA. This component has been thoroughly tested to meet RS PRO standards. It can safely be utilised in a temperature range between -30°C and +85°C. You're likely to find it in alarms and warning devices, as well as telephone dial tones and toy or game sounds.
