Piezo buzzers with LED beacons are especially designed for flush mounting. This makes the ESG piezo buzzer the loudest built-in alarm buzzer available on the market.Īuer Signal piezo sounders have a wide voltage range from 8-24 V AC/DC to 150-260 V AC. The piezo speakers are available in the sizes 30mm, 45mm or 65mm and achieve a maximum sound pressure of 105 dB. The alarm buzzers of the Series M22 have a mounting dimension of 22,5mm (M22) and are therefore suitable for simple, standardized single-hole mounting. Our built-in Series M22 – the Installable – consist of built-in beacons, piezo buzzers and visual-audible combinations. Their small size allows them to be used in applications with very limited space as well as easy mounting (built-in dimension M22). What are the advantages of piezo sounders?ĭespite their small size, piezo sounders achieve an enormous sound pressure, have a low power consumption and are also cost-effective. The buzzer sound produced by these devices is sharp, clear, and attention-grabbing, making them an effective means of signaling in different environments. Piezoelectric buzzers achieve frequencies between 2.000 to 4.000 Hz, low tones can not be generated with this technology. The higher the voltage, the greater the vibration of the piezo crystals. By applying electrical voltage, the crystals on the disk generate vibrations and the buzzer sound is produced. Inside the piezo buzzer is a piezo disk with piezo crystals. Piezo technology is the interaction of mechanical pressure and electrical voltage in solids. The word „piezo“ is derived from ancient Greek and means to press and was discovered first in 1880 by the brothers Jaque and Pierre Curie on tourmaline crystals. How does the piezo buzzer technology work? Piezo sounders are suitable for audible warning at near distances, but still achieve a sound pressure of up to 105 dB. They are especially used in control cabinets and control technology. The are mostly used when there is only limited space available for the signaling device. Piezo buzzers are among the smallest audible signaling devices.
