370Hz Piezoelectric Benders Using all ceramic design to replace the traditional bimorph, ceramic + metal (polymer / carbon fiber) + ceramic structure design, making its output much greater than ordinary bimorph. The bimorph has a double-layer design. When voltage is applied, one layer shrinks and the other expands, resulting in deformation.
Benders：HCBR3919T3
Drive Voltage：150V
Dimensions：39×19×3mm/32×7.8 x0.8mm
Capacitance：550nF±15%
Resonant Frequency：370Hz
Displacement：±450µm±15%

The fixed end of the bimorph has three electrodes: the red wire is connected to the positive electrode, the black wire is connected to the negative electrode, and the white wire is the common electrode.
Unilateral drive:
Red wire 0 ~ 150V, white wire 0V;
White wire 0 ~ 150V, black wire 0V.
Bilateral drive:
Red wire + 75V, black wire – 75V, white wire – 75 ~ + 75V;
Red wire + 150V, black wire 0V, white wire 0 ~ + 150V.
930Hz Piezoelectric Benders Characteristic：Multilayer all ceramic technology，Submicron resolution，Low pressure drive, high output，Low power consumption, anti magnetic interference，It can be used in vacuum environment，Size / voltage can be customized.
