The Sonitron Multi-Application Round 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.

* All measurements are made in free air @ 21°C @ 30cm @ 12Vdc (Except for the SMA-21LV & SMA-30 L). Buzzers soldered
on a PCB board with dimensions of 24cmx11cm.
** SMAI 24: intermittent pulse rate of 5Hz (@ 15Vdc). All the other models have a continuous tone.
