Piezo buzzer Sonitron SMA-13LV deploys maximum from a minimum

Belgian company Sonitron and its top-level products ar probably familiar to you from our articles and from our offer in this segment. We continue in increasing of standard stock types and this time we have here an extraordinary interesting type – SMA-13LV, interesting mainly for low-voltage applications. Series of buzzers marked as “SMA” is known by its variousness, as we find here types with loudness of 75-98 dB, THT and SMT versions, and versions with a stable, as well as intermittent signal. Various sizes from 13 to 30 mm with a pitch of 7.5 to 20.32 mm enable to select the right type for a given application. In general, bigger types provide a more loud signal, but it depends on a concrete type. This series is suitable for general use – everywhere, where a reliable buzzer is necessary, including industrial conditions.

For a succesful use, it´s only necessary to connect a suitable supply voltage – usually in extremely wide range (for example 1.5-15V). Usually, on the upper end of a supply voltage range we get the highest loudness and at lower voltages we receive a higher lifetime.

Very similar is also the SMAT series (transducers), which in contrast to the SMA series doesn´t contain a driver, that´s why it needs extenal electronics.

For really tough conditions, the Sonitron SAP. series is suitable. These are buzzers for various usage in traffic, for example as a reverse movement indicator (danger of close approximation). They excel in extreme rigidity, what make them widely used even in avionics, miltary and trucks. SAP series has a specific usage, that´s why we keep these types as items upon request.
