High Frequency Piezo Actuators (PSA)

High Frequency Piezo Actuators (PSA)

DSM’s high frequency actuators are linear contracting motion actuators with displacement values ranging between 350 µm to 1500 µm. The actuator’s minimal moving mass results in exceptionally high resonant frequencies. DSM can customize and/or scale this actuator architecture for OEM applications.
