RS PRO 88dB Panel Mount Fast Pulse Internal Piezo Buzzer, 43 (Dia.) x 20mm, 6V dc Min, 28V dc Max

Need an alarm that will be sure to get your attention? This piezo buzzer from RS PRO will sound at 88 dB, a similar noise level to a food blender. It also pulses fast to alert you when time is of the essence.
The DC buzzer's internal drive means it doesn't require any additional circuitry, making building systems an easier job easier for systems engineers. It's designed for mounting into a panel, so you can build it into a device.
The buzzer conforms to US (ANSI/ESD S20.20:2014) and UK (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 in devices ranging from door alarms to pest deterrents.
