Description
Technical Data

The ultrasonic transducer is composed of a shell, a matching layer, a piezoelectric ceramic disc, a backing, a lead-out cable, and a Cymbal array receiver. The ceramic disc is made of PZT-5 piezoelectric material, polarized in the thickness direction, while the Cymbal array receiver consists of 8 to 16 Cymbal elements, two metal rings, and rubber gaskets.

An ultrasonic transducer can also be described as an ultrasonic emitter: through the piezoelectric effect, it converts electrical energy into mechanical energy, and its high-frequency vibration radiates ultrasonic waves.

When selecting an ultrasonic welding transducer, the most critical considerations are the matching of input and output terminals, followed by mechanical installation and mounting dimensions. If you need ultrasonic transducers, please provide accurate specifications so that we can supply products perfectly matched to your machines for optimal performance.

MCSONIC offers 15 kHz, 20 kHz, 35 kHz, and 40 kHz transducers in various sizes, and fully customized piezoelectric transducers are also available.
