Sonitron New SMA & SMAT Series

The Sonitron Multi-Application buzzers (SMA) and transducers (SMAT) are specifically developed to meet a wide range of requirements in sound pressure, dimensions, and mounting methods. These series produce highly reliable audible signals, giving either an extremely clear penetrating tone or a soft sound output. The buzzers and transducers are low-cost commercial-grade components for large volume applications.

Advantages SMA  

  • Octagonal form
  • Models with different pin pitches
  • Light but solid-state construction
  • Little power consumption, especially the extra loud LC-versions
  • Wide voltage range ( 1.5V to 24V)
  • Easy mountable
  • SMA-13 and SMA-17 for applications with limited space
  • SMD models with heat resistant label for protection during automatic soldering
  • Automatic Pick & place

*All measurements are made in free air @21°C @30cm @12Vdc ( Except for the SMA-21LV & SMA-30L). Buzzers soldered on a PCB board with dimensions of 24cm x 11cm.

** SMAI 24: intermittent pulse rate of 5 HZ (@15 Vdc). All the other models have a continuous tone.

Operating temperature  -20°C to +70°C
Storage temperature -40°C to +85°C
Lifetime (at 21°C) @12Vdc (L-version working @6Vdc) continuous use min. 100 hours. The SMA-21LV (PIN/SMD) working @3Vdc in continuous use: min. 24hours. All tests are made @20°C mounted on PCB
