RS PRO 92dB Panel Mount Continuous, Fast Pulse Internal Piezo Buzzer, 35.5 (Dia.) x 23.5mm, 6V dc Min, 28V dc Max

Need to install an audible signalling device where space is tight? This RS PRO piezo buzzer is compact and made from lightweight plastic, so it's easy to fit on your control panel. It produces a continuous, fast-pulsing sound at 92 decibels (dB), so it's suitable for use as an alarm or sounder.
This buzzer comes with three pins ready for installing on a PCB (printed circuit board). It has DC (direct current) circuitry, so it's compatible with a wide range of low voltage electrical appliances.
Piezo buzzers are found in devices such as domestic and commercial smoke alarms and theft deterrents. This component has been thoroughly tested for quality and meets American (ANSI/ESD S20.20:2014) and European (BS EN 61340-5-1:2007) electrostatic control standards.
