WNAP series piezoelectric displacement actuators adopt advanced flexure mechanism and high performance piezoelectric ceramic stack, which can provide a very large range of motion, fast response speed and sub-nanometer resolution. Double hinge flexure mechanism has higher stiffness, mechanical efficiency and resonance frequency. The double hinge flexure design also makes the size more compact. Product parameters can be customized.
Application
Applications of WNAP series piezoelectric displacement actuators include nano-positioning, biomedicine, microscopy, precision machining, vibration control, high-speed valves and optics.
