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.
ADVANTAGES & APPLICATIONS
ADVANTAGES:
• octagonal form
• models with different pin pitches
• light but solid construction
• not fixed working frequency
• easily mountable
• SMD models with heat resistant labels for
protection during re-flow soldering,
• packed in a tray for automatic placing
APPLICATIONS:
• audible alarms
• gas detectors
• measuring and weighing equipment
• medical instrumentation
• timers
• instrumentation and control systems
• copiers
• automobiles
• games & toys
• cash registers, etc.
