Closed-Loop Control: High-Resolution and Stable Linear Actuator Now also Available with Position Sensor

The N-472 keeps a position with long-term stability and is vibration-proof and shock-resistant. Like the N-470 open-loop version, the N 472 achieves its high holding force and resolution by a piezomotor turning a fine pitch screw.

The incremental encoder measures the relative motion to a freely definable reference position. In combination with the E-871 motion controller the encoder resolution is up to <1 nm.

Even with an integrated position sensor, the N-472 PiezoMike linear actuator retains a compact design and can be integrated in conventional mirror mounts or stages.

PI offers the closed-loop N-472 actuator for 7.5 mm and 13 mm travel range with a motion resolution of a few nanometers and excellent repeatability. Optional use in a vacuum down to 10-6 hPa is also possible.

The piezomotor drive is self-locking at rest, even when closed-loop control is switched off, and therefore requires no current and generates no heat. It ensures a reliable start-up, even after longer downtimes.
