Ultrasonic Welding High Mechanical Quality factor and excellent electro-acoustic conversion efficiency, providing high output Main FeaturesHigh Mechanical Quality factor and excellent electro-acoustic conversion efficiency, providing high output amplitude. Piezoelectric element offer a high speed of vibration. Through bolt-on presstress, mechanical and amplitude have been improved. Having steady output amplitude even under markedly changed loads. Extended temperature use, ensuring good amplitude linearity. Low resonant impedance ensuring high conversion efficiency.  Bolt-on pre-stressed design provides fast and easy installation with high reliability. Product CodingWelding Transducers Selection Chart
