Piezo LEGS® Linear Twin 20N Non-Magnetic Vacuum

LT20 version 20D — Non‑magnetic — Vacuum

The twin concept makes for high force output in a very compact body. In a non-magnetic version, the housing is made from non-magnetic material and the motor is therefore suitable for the most senesitive applications . The motor performs sub-micrometer resolution in combination with motion truly free from any backlash. Full force power-off locking is a safety function inherent to the design.

  • Non-magnetic and suitable for sensitive equipment

    This is a non-magnetic and vacuum compatible version of the well proven LT20 motor. In a twin configuration with Piezo LEGS® actuators on both sides of the drive rod, the motor outputs very high force compared with its compact size. Direct friction drive means motion free from any backlash or mechanical play. The resolution is sub micrometer and extends to single nanometer level if so required. Quick response and settling time ensures steady position hold in closed loop. Piezo LEGS® technology is perfect for very accurate point-to-point positioning, as well as motion over a large dynamic speed range (nanometers per second to millimeters per second).
