The PA series of actuators are internally pre-loaded by a mechanical spring, making them ideal for dynamic applications. The ability to generate a large force and be subjected to high mass loading make them particularly useful for machine tools and dynamic scanning systems. As an option, these actuators are available with strain gauges. This option will increase the length or the outside diameter to 14 mm and the accuracy to < 0.5%.
A note on mounting these actuators:
Actuators are normally fastened with screws or clamps to the bottom plate. If the top plate has a torque nut, it should be used when securing screws in order to avoid damage to the actuator. Please avoid tensile forces greater than the given pre-load!
applications:
- mirror shifting
- laser tuning
- micro injection
- semiconductor
- nanopositioning
