Stack Type Actuator Series PA
Stack Type Actuator Series PA

Summary

Concept:

The PA series actuators are based on stack type actuators made by using multilayer technology. The PA series stack type 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. These actuators have a uniform diameter of 14 mm.

Mounting:

Actuators should be fastened with screws or clamps on the bottom plate of the actuator. During the installation and use, it is important not to subject the actuator tip to non-axial forces. The actuator head is available in two versions, round head piece for standard version and flat head piece with M3 thread on demand.

Configuartion:

Please choose the suitable stroke, head piece, feedback and electrical interface to your application or ask our sales.

Applications:

  • Nano positioning
  • Scanning microscopy
  • Micro manipulation
  • Micro injection
  • Optical adjustment
  • Laser fine tuning
  • Mirror adjustment
  • Mirror positioning
