Details
Low-voltage piezo actuator is preloaded low-voltage piezo stack inside, and the outside is protected by a cylindrical stainless steel shell. The preloaded piezo actuator can withstand a certain pulling force, and is suitable for high load and high-dynamic applications.
Characteristics
• Nanoscale resolution
• Optional closed-loop sensor
Closed Loop and Open Loop
Preloaded piezo actuators are available in open loop (no position feedback sensor) and closed loop (integrated position feedback sensor) versions. In its open-loop mode, the resolution is infinitely high, limited only by the noise of the controller, and it also features the hysteresis and creep. In its closed-loop model, the hysteresis, creep and non-linearity are ruled out to make it linear.
Multiple Ends
• Plane
• Spherical
• Internal thread
• External thread
