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.

@12Vpp continuous use at resonance frequency, tested on
maximum sound pressure (eg. SMAT-21 @ 3.75 kHz). Life
expectations: min.1000 hours. All tests are made @ 20°C mounted
on PCB (expected life time curve in addendum).
* All measurements are made in free air @ 21°C @ 30 cm @10 Vpp (square wave). The test buzzer is soldered on a pcb
board with dimensions of 24 cm x 11 cm.
