VS9 Preloaded Linear Actuators, OD9mm, 0-150VCurrent Location：Product Homepage >> Preloaded Piezo Actuators>>VS9 Preloaded Linear Actuators, OD9mm, 0-150V
  • Introduction
  • Feedback

Low voltage preloaded piezo actuator is obtained by encapsulating the low-voltage piezo stacks inside, the outer part is protected by stainless steel casing, and the pre-tightening force is applied to the piezo stacks through the mechanical casing, the higher internal machinery preload force is suitable for high load, high dynamic applications. It could output the displacement and output generated by the piezo stack and could withstand certain tensile force.
