High Precision Micro-Positioning Actuators Available for Fast Delivery

22 Oct 2025

For applications requiring sub-micrometer precision, PI's L-220 series linear actuators provide reliable, high-precision motion in a compact design. Engineered for demanding tasks in optics, photonics, semiconductor testing, metrology, and microscopy, select models are available with short lead times to support fast system integration.

PI's motorized high-resolution actuators combine precision and force in a compact form factor. With travel ranges from 13 to 77mm (½" to 3") and feed forces up to 125N, 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 or stepper motors, L-220 actuators achieve speeds up to 3.5mm/s and minimum incremental motion down to 0.1µm. The actuators are self-locking and provide high holding forces for position stability without continuous power.

Vacuum Rated Variants
The L-220 linear actuator is also available for vacuum environments up to 10-6 hPa and for cleanroom applications.

Applications
Used worldwide—from semiconductor fabs to optical labs—L-220 micro-positioning actuators provide precision motion, repeatable 100nm steps and high reliability. With fast availability, they enable design engineers to respond quickly to new project requirements and maintain a competitive edge.
