These ceramic piezo transducer elements generate a range of audible tones & frequencies when energised by 3V peak square wave. They can be driven direct from CMOS ICs with low power consumption. They are supplied unhoused & with wires attached. Provided they are mounted rigidly in the prescribed manner outputs of up to 90d B can be achieved. In addition to a wide range of applications where audible warnings or indications are preferred to visual other uses include toys clocks & watches calculators & electronic games using the transducer in place of a speaker. Because there are no moving parts to wear out these elements are reliable for use in professional commercial & industrial applications. They withstand severe environmental conditions & prove durable in domestic appliances without causing r.f. interference. A range of different sizes are available.
