1.2. Multi-Application Series (SMA & SMAT)
1.2.1. INTRODUCTION
The Sonitron Multi-Application (SMA) series of buzzers and transducers are specially
developed to meet a wide range of requirements in sound pressure, dimensions and
mounting methods. These series produce highly reliable audible signals, giving an extremely
clear penetrating or soft sound output. Both, buzzers and transducers, are now 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.
Moreover, they all 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 models SMA-21 generate an extremely loud sound output at very
low battery voltage starting at 2 Vdc up to 6 Vdc.
• Due to 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 mean time between
failure 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.

1.2.2. SELECTION GUIDE
Selection of an acoustic signal can be complex. Therefore the list below indicates the most
recommended applications for our products at a certain distance and frequency.
Nevertheless, it is important to take into account that every application is different and that
the perception of a sound is very subjective.

1.2.3. SMA BUZZERS
The Sonitron Multi-Application buzzers are
low cost commercial grade components for
large volume applications. The SMA series
are designed to meet a wide range of
current consumption, voltage, sound
pressure, mounting methods, connection,
dimensions and packing requirements. 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.
