The PICMA® Stack piezo linear actuators from PI Ceramic feature linear displacements with low piezo voltages. Encapsulated versions for operation with splash water or oil are available.
The miniature actuators PICMA® Chip with a height of only 2 mm are also offered as round version with inner hole. These extremely compact piezo actuators feature maximum dynamics with high resonant frequencies. PICMA® Chip piezo actuators can be easily combined to stack actuators.
