Piezoceramic Disc for Ultrasonic Skin Shovel OD33x1MHz

Piezoceramic Disc for Ultrasonic Skin Shovel OD33x1MHz

Basic Info

    Model No.: OD33*2mm PBaS-4

Product Description

Piezoelectric ceramic disc

Quick shipments

High performance

wrapped arround electrode available


Application: ultrasonic beauty shovel


Ultrasonic Transducer for cosmetic spade

It provides a new method of health care and skin care for people. It adopts physical therapy and carries out safe and effective health care according to the characteristics of human skin. The shovel head vibrates 25,000 times per second to decompose and derive the dregs and dead skin in the pore. Regular use can shrink pore, tighten skin, fade spots, smooth wrinkles, so that your skin restores health and elasticity, bloom youth and luster. Using low voltage power supply, it is safer and has longer service life.

Material: PBaS-4 (hard PZT, very high dielectric constant 1900 and high Qm 2200)


PBaS-4 is a modified hard PZT dedicated for extremely high power high driving etc. transducers with higher power handling capability than PZT-4 series.
