Multi-Application Transducer
SMD & Pin version
Pagina 1 van 4
Both the SMA buzzers and the SMAT (Sonitron Multi-Application)
transducers are specially developed to meet a wide range of
requirements in sound pressure, mounting methods, connection
possibilities and dimensions. The transducers do not have a built-in
oscillator. The drive frequency must be generated with electronics
outside the transducer. Recommended drive circuits are described in
this catalogue. Our transducers produce a highly reliable audible tone
signal, giving either an extremely clear and penetrating tone or a soft
sound for non-aggressive signals. They are available in five sizes:
13mm, 17mm, 21mm, 24mm and 30mm.
