Min. incremental motion 0.05 µm Travel ranges 10 and 25 mm Nonrotating end piece Velocity 0.8 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. High-quality components Extremely low-friction and backlash-free construction. Nonrotating end piece for uniform motion prevents wobble, torque, and wear at the point of contact. Includes flat and spherical end piece for decoupling of lateral and tilt forces. Noncontact limit switches protect the mechanical system. Closed-loop variants with differential encoder driver for a safe position signal transmission at distances up to 10 m Application fields Precision alignment, motorized replacement for micrometer screws.
