Specification :

High Mechanical Quality and excellent electro-acoustic conversion efficiency,providing a high ouput amplitude.
Piezoelectric element offer a high speed of vibration. Through bolt-on mounting, mechanical intensity and amplitude have been

improved.
Having steady output amplitude even the load markedly changed.
Extended using temperature, ensuring god amplitude linearity.Lower resonant impedance, ensuring high conversion efficiency.
Bolt-on mounting gives the fast, easy installation and high reliability.
