KEMET Disc Shape Piezoelectric Transducers are piezoceramics that use original high-performance piezoelectric materials. These transducers are based on the principle of the piezoelectric effect and generate a charge in response to pressure and an inverse piezoelectric effect. The disc shape piezoelectric transducers operate from -20°C to 60°C temperature range and are RoHS and REACH compliant. These transducers are ideal for vibratory feeders, ultrasonic cleaning machines, ultrasonic levitation, ultrasonic flow and level meters, and ultrasonic distance, load, and impact sensors.
