Multilayer Stack Ring Actuator 9.5x5.5x10mm 10um Displacement

Part Number: SMPAK955510D10R

Stack piezo ring actuators are used as linear electromechanical drivers or motors. They act mainly like an expanding element generating a compressive force. The complete motion cycle is nearly proportional to a voltage signal input from DC up to high frequencies. Compact size, accurate positioning in nm, high-speed response and large blocking force. High energy conversion efficiency, low power consumption and no electromagnetic noise. Easy to be controlled by voltage.
