Why Choose Our Piezo Buzzer
Piezo buzzers has been more and more popularily used as there is no magnetic field and no coil inside. Typically, piezo buzzers consume less current (less than 30mA), have a broader frequency range (2-6kHz) and wider operating voltage (3- 250V), and generate a higher SPL.
Kailitech piezo buzzers include types of taping, SMD, ultra-low frequency, high SPL, waterproof, high temperature and pressure resistant, with diameter or length and width fm 9.0mm to 100mm, height fm 1.8mm to 65mm, with resonant frequency range fm 200Hz to 15kHz and SPL range fm 65dB to 120dB. Housing material can be ABS, PBT, PPO, LCP, etc.
The main characteristics of Piezo Buzzers are >>
Smaller size, lighter weight, suitable for installation on various circuit boards.
High electric – acoustic power conversion efficiency (above 75%) .
Low power consumption, P≤3V*10mA=0.03W.
High reliability, long durability. The performance and degradation is the log relationship, and the degradation of performance is less than about 5% in 30 years.
No magnetic field, no coil, no electromagnetic interference.
