The buzzers, as the light signalling, are used to communicate messages to the operator. The characteristics of the buzzers for panels are:

Our buzzers are piezoelectric audio devices.
In the case of buzzers, the piezoelectricity is the property of deformation of some crystals when they are subjected to an electrical voltage. This piezoelectric effect occurs only in a particular direction, and the associated deformations are in the nanometer range.
When applying a potential difference to the crystal, it expands or contracts causing a vibration that, if controlled, allows the sounds creation.
Our range of buzzers for panel application is wide and includes a big range of operanting voltages both AC and DC.
Several buzzers are multi-tone (continuous or pulse sound) as they are multichannel also allow remote control.
All buzzers are available with high acoustic intensity, up to 100 dB and low current consumption, just a few mA. This last feature allows direct control by electronic circuits without the need for expensive joining equipment.
The buzzer type ECX55 is distinguished by other models, because in addition to the great power, it emits low frequency sounds that allow an optimal diffusion even in industrial settings.
