Static and dynamic precision positioning, Laser tuning
Preloaded Piezo Actuator is an armored device for Piezo Stack Actuator, which plays a role in stack protection and easy installation. At the same time, the actuator applies pre-pressure to the piezoelectric ceramic internally, providing a certain amount of tension and adjustment of displacement output. Preloaded Piezo Actuator can be internally integrated with strain gauges to achieve closed-loop control.
The default output end is an external thread, and other output end structures can be customized.
