SMB Series

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.
