The shear-type piezoelectric ceramic stack is a stacked device composed of multiple piezoelectric ceramic shear plates bonded together. By superimposing the shear displacements of multiple plates, a larger overall displacement is achieved. The shear stack can produce displacement in one-dimensional to three-dimensional XYZ directions, with a maximum displacement of up to 13 μm in a single axis, and the drive voltage of each ceramic layer can be independently controlled.

Drive Voltage: Different drive voltages can meet various displacement requirements. Common standard voltages available include 100V, 150V, and 250V.
Output Displacement: The output displacement is related to the stack height. Depending on different application scenarios, a maximum shear displacement of up to 20μm can be provided.
Operating Frequency: High - frequency driving may cause damage or heating of the shear stack device. A maximum drive frequency of up to 20kHz is provided.
Dimensions: In terms of length and width, options such as 4mm, 6mm, 8mm, and 10mm are available. In terms of height, the maximum selection is 15mm.
Wiring Harness: Under the condition of meeting the AWG usage standards, the wiring harness is optional. For convenient connection of the positive and negative electrode wires, the soldering point position can be selected within the allowable error range of performance variation.
