Sonitron SMB-series ( multi-frequency buzzers) offer the possibility to program several different frequencies. These audible signals with multi-frequency programmability will become an important component that must be considered in every design of equipment, machines, household equipment, computers, communication equipment, control panels, etc.

Mounting guidelines
Working principle | In order to realize different frequencies with the SMB multi-frequency buzzers, the customer should simply connect a capacitor between the control pin and the ground. It is also possible to disable the SMB, by putting a resistor (47K) to the ground (INHIBIT). |
Typical application description | With the circuit shown below, 16 possible frequencies can be generated. The value of C1, C2, C3,…with their respective frequencies are given in the graph ‘frequency vs.external capacitor. |
