(PI Americas: Auburn, MA) -- For tasks requiring submicrometer precision, such as alignment, adjustment, or fine positioning, PI’s M-235, L-220, and M-230 series linear actuators deliver reliable, high-performance motion. These compact actuators are ideal for demanding applications in optics, photonics, semiconductor testing, metrology, and microscopy, with select models available on short lead times for rapid integration. 

High-resolution stepper and servo motor linear actuators

PI’s motorized high-resolution actuators combine precision and force in a compact form factor. With travel ranges from 10 mm–77 mm and feed forces up to 125 N, they support a broad range of applications. Their low backlash and nonrotating, linearly guided tips minimize tilt and eccentricity-caused errors, as is common with low-cost, rotating-tip type actuators—ensuring accurate, repeatable motion.

Available with closed-loop DC servo and stepper motors, these actuators reach speeds up to 30 mm/sec and achieve minimum incremental motion (smallest repeatable step size) down to 0.05 µm. Self-locking versions provide high holding forces to ensure position stability without continuous power.

Engineered for continuous operation, the actuators offer a mean time between failures (MTBF) of up to 20,000 hours and withstand frequent load changes. Vacuum-compatible versions are available for cleanroom and high-vacuum environments.

Applications

In use worldwide—from semiconductor fabs to optical labs—M-230, M-235, and L-220 actuators serve as precise external drive elements for linear, tilt, or rotational motion. Their fast availability helps users adapt quickly to changing demands and maintain a competitive edge.
