High Precision Actuators with Stepper Motors and Servo Motors.
For tasks requiring sub-micrometer 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.​​​
PI’s motorized high-resolution actuators combine precision and force in a compact form factor. With travel ranges from 10 to 77 mm and feed forces up to 125 N, they support a broad range of applications. Their low backlash and non-rotating, linearly guided tips minimize tilt and eccentricity-caused errors, as 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.
