MULTI-APPLICATION SERIES
SMA & SMAT
INTRODUCTION
The Sonitron Multi-Application (SMA) series are specifically developed to meet a wide range of
requirements in sound pressure, dimensions and mounting methods. This series produce highly
reliable audible signals, giving either an extremely clear penetrating tone or a soft sound output.
Both, buzzers and transducers, are available in five sizes, 13 mm, 17 mm, 21 mm, 24 mm and 30 mm.
All SMA products are manufactured to meet various mounting styles such as through-hole or
surface mounting technologies (SMD). Therefore they are equipped with either pin or SMD
terminals.
The Multi-Application series present the following advantages:
·
The octagonal housing provides alignment with pick & place machines for SMD models,
which are packed in trays and protected with a heat resistant label for automatic soldering.
·
The miniature models SMA-13 and SMA-17 offer a high sound pressure level together with a
clear audible tone.
·
The LT-versions of the models SMA-13, SMA-17 and SMA-21 generate an increased sound
output. The LC-versions of the same models operate at extremely low current consumption;
ideal for battery operated applications.
·
The LV versions of the model SMA-21 generate an extremely loud sound output at very low
battery voltage starting at 2 Vdc up to 6 Vdc.
·
Because of the same case style for buzzers and transducers with different pin pitches per
model, the user is offered a great deal of flexibility and can switch over to a buzzer or
transducer at any time.
·
The piezo audio technology can be qualified as solid state, highly reliable, without EMI and is
able to withstand temperatures from -40°C to +85°C. The MTBF exceeds in reality
several times the figure indicated in this catalogue. Lifetime depends on different factors
and is described more in detail in the addendum.

SMA SERIES
The Sonitron Multi-ApplicationRound
buzzers are low cost commercial
grade components for large volume applications. The SMA series
are designed to meet various requirements such as current
consumption, voltage, sound pressure, mounting methods,
connection, dimensions and packaging. They are available in five
sizes: 13 mm, 17 mm, 21 mm, 24 mm and 30 mm.
The buzzers have a built-in oscillator generating their working
frequency. They produce a highly reliable audible tone signal,
giving either an extremely clear and penetrating tone or a soft
sound for non-aggressive signals.

SMAT SERIES
The SMAT transducers are specifically developed to meet various requirements, such as loud
sound pressure level, 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.
