  • Nanometer resolution and micrometer displacement
  • Load capacity up to 4000 N per actuator
  • Temperature sensor
  • Long-term stability without a permanent power supply
  • Easy readjustment of machines at inaccessible locations
  • Avoids time-consuming manual adjusting processes

Fields of Application

  • Precision mechanics
  • Static precision positioning
  • Metrology/interferometry
  • Set-and-forget applications
  • Adaptive mechanics
  • Drift compensation
  • Alignment of optical components

High User-Friendliness Due to Automatic Configuration

When the electronics are turned on, the mechanic’s ID chip, which contains crucial operating characteristics, is automatically read out.

Long-Term Stable Positioning Without Permanent Power Supply

Actuators equipped with PIRest technology keep their position steadily after being moved without a constant control voltage supply. Modifications are affordable, easy to maintain, and with nanometer precision even at remote sites.
