RS PRO 85dB Through Hole Continuous External Magnetic Buzzer Component, 12 x 9mm, 3V ac Min, 8V ac Max

This PCB mounting magnetic buzzer will emit 85 dB of continuous sound once connected to an external drive. You can use it in residential and business settings including houses, industrial plants and garages.
The piezo buzzer is easy to install, as it's simply fitted directly onto a printed circuit board (PCB) and soldered into place. With a weight of just two grams, it's suitable for through-hole mounting onto surfaces with a limited load-bearing capacity. The component is housed in a circular case with a sealed base, which means it's protected from dust and lasts longer.
