sma smat series

SMA & SMAT Series

The Sonitron Multi-Application buzzers (SMA) and transducers (SMAT) are specifically developed to meet a wide range of requirements in sound pressure, dimensions, and mounting methods. These series produce highly reliable audible signals, giving either an extremely clear penetrating tone or a soft sound output. The buzzers and transducers are low-cost commercial-grade components for large volume applications.
