The stack type actuators of the series PA / T based on the standard PA series. A Special feature is the outside threading of M14 to mount the actuator. It also helps to adjust the position precisely.
These actuators are mechanically pre-loaded to make them ideal for dynamic applications. The ball tip end plate allows movement of components without shear stress on the ceramic inside. All these features make them ideally suitable for screwing into mechanical stages for precise adjustment of other optical components such as mirrors. To overcome the effect of drift and hysteresis, the actuator can be equipped with a high resolution strain gauge feed back sensor. The typical accuracy is 0.5% of the motion.
