They are available in five sizes: 13 mm, 17 mm, 21 mm, 24 mm and 30 mm. The buzzers have a built-in oscillator generating their working frequency. They produce a highly reliable tone signal giving either an extremely clear and penetrating tone or a soft sound for non-aggressive signals.

The SMAT transducers do not have a built-in oscillator. The drive frequency must be generated with electronics outside the transducers.

SC 235 series
The standard series are based on the highest piezo technology and are considered as most robust series for industrial applications. The standard buzzers use a special shaped membrane (curved edge), which is fixed and glued into the housing. They are shock proof, as well as dust and waterproof (IP67). The different standard models cover a wide range of applications, offering functions such as continuous, intermittent, sweep and warbler, with a sound output more than 100dB(A). All standard buzzers are available with various mounting methods, such as PCB or panel mounting and therefore are equipped with either pins or fast-on terminals.
