Overview
Travel ranges 10 mm and 25 mm, minimum incremental motion 0.05 µm, velocity up to 1.2 mm/s, MTBF >20000 h
Precision-class linear drive
High-resolution linear actuator. Position-controlled DC motors with a gearhead and high-resolution rotary encoders allow for incremental motion and repeatability of just 100 nm. Powerful and low-vibration 2-phase stepper motors with gearhead allow for smooth and accurate open-loop positioning.
High-quality components
Extremely low-friction and backlash-free construction. Nonrotating tip for uniform motion prevents wobble, torque, and wear at the point of contact. Incl. flat and spherical tip for decoupling forces. Noncontact limit switches protect the mechanics. Position-controlled variants with differential encoder driver in the connector for safe signal transfer over distances up to 10 m.
Application fields
Precision alignment, motorized alternative for micrometer screws.

At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
