930Hz 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：HCBR208T008
Drive Voltage：150V
Dimensions：20×8×0.8mm / 27.0 x 19.0 x 3.0 mm
Capacitance：145nF±15%
Resonant Frequency：930Hz
Displacement：±135µm±15%
Blocking Force：1.4N
These bimorphs are fabricated by tape casting and co firing techniques with high reliability and are ideal for optical choppers, pipe benders, pumping and metering applications.
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.
