You can optimise the lifespan of your Sonitron buzzers and transducers by adding product options that can strengthen them and make them more robust.Option SP02The special option SP02 contains internal heavy duty wires (plastic insulation) and the solder joints are sealed with silicone.Sonitron Cup technologyChoosing a Sonitron buzzer with cup technology ensures maximum lifetime.  The robust internal mechanical construction of the SMAC25 makes it possible to have a lifetime of a minimum 1000 hours.SMATThe 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 transducers.  Our transducers produce a highly reliable tone signal, giving either an extremely clear and penetrating tone or a soft sound for non-aggressive signals.They are available in five sizes : 13 mm, 17 mm, 21 mm, 24 mm and 30 mm.SMAC-25Piezo acoustic components are more and more used in small portable equipment and as a critical alerting device.  Reliability must be very high in the most difficult environmental circumstances, such as extreme and varying temperatures, vibrations, shocks, dust conditions, humid environment, etc.The SMAC-25 buzzer, manufactured with over 30 years of experience in the field of piezo acoustic technology, is a very stable buzzer with a lifetime of more than 1.000 hours in continuous use.  In these small dimensions, the SMAC-25 is actually the best available piezo alarm for life supporting systems.Please phone 01494 791336 or e-mail [email protected] for further information or to request a quotation.
