Sub-nanometer resolution positioning with a 90 µm stroke and 1000 N pressing force, with a microsecond response.
The P-841 is a piezo actuator that incorporates a PICMA® multilayer stack in a preloaded metal case. It operates with a displacement of up to 90 µm at the nanometer level, providing a pushing force of 1000 N and a pulling force of 50 N. A variety of displacement ranges from 15 to 90 µm are available. The ceramic insulation technology of the internal piezo reduces leakage current and moisture intrusion, maintaining performance even during long-term continuous operation. Equipped with a strain gauge position sensor (SGS), it accurately corrects hysteresis and drift. It excels in applications requiring high rigidity and high responsiveness, such as alignment of fibers and optical elements, laser wavelength tuning, and nanotechnology testing fixtures. *For more details, please download the PDF or contact us.*
