Sonitron New SRA Series
Since 1977, Sonitron continuously invested in research and development, optimising their standard series which are used today under the most extreme and difficult environmental circumstances, by clients such as the Nato, Airbus, Volvo Penta, Dräger, Knogo,…
During the last 30 years, the standard series have proved to be the prime alarm, giving your equipment an added value. Several thousands of clients all over the world have chosen for the reliability and the excellent quality of piezoceramic buzzers of Sonitron.
These series are strongly recommended in applications that are critical and life time in continuous function is tested. Critical applications are life support systems and equipment used to warn for life danger such as: portable gas detectors, medical monitoring equipment, aircraft cockpit alarm’s, car breaking alarm’s etc…
The standard series are based on the highest piezo technology and are considered as the most robust series for industrial applications. The standard buzzers use a special shaped membrane (curved edge), which is fixed and glued into the housing. They are shockproof, as well as dust and waterproof (IP67). The different standard models cover a wide range of applications, offering functions such as continuous, intermittent, sweep, and warbler, with a sound output more than 100 dB(A).
All standard buzzers are available with various mounting methods, such as PCB or panel mounting and therefore are equipped with either pins or fast-on terminals. The standard series include military models, extra loud types, as well as models operating at very low voltage consumption (SC 0715 BL at 0.7V) and very low current (SP27 = 4,8 mA at 9V).
The Sonitron Robust Application standard series are an important extension of the Standard series. A superior Life Time has been obtained with a very large DC voltage range from 5Vdc up to 80Vdc. Equipped with 16 AWG wires this buzzer can be used in any harsh industrial environment. These series are recommended in critical applications and life support systems.
