Linear Actuators For Micropositioning And Precision Alignment
For applications demanding sub-micrometer precision—such as fine positioning, alignment, or adjustment—PI’s M-235, L-220, and M-230 linear actuator series provide reliable, high-performance motion control.
PI’s motorized high-resolution actuators deliver precise force and motion in a compact design, offering travel ranges from 10 to 77 mm and feed forces up to 125 N. Their low backlash and linearly guided, non-rotating tips reduce tilt and eccentricity errors commonly seen in rotating-tip actuators, ensuring accurate and repeatable positioning.
Available with closed-loop DC servo and stepper motors, these actuators achieve speeds up to 30 mm/sec and minimum incremental motion as fine as 0.05 µm. Self-locking variants provide strong holding force for stable positioning without continuous power.
Designed for continuous use, they feature a mean time between failures (MTBF) of up to 20,000 hours and handle frequent load variations. Vacuum-compatible models are also offered for cleanroom and high-vacuum applications.
Widely used across industries—from semiconductor manufacturing to optical research—PI’s M-230, M-235, and L-220 actuators serve as precise external drives for linear, tilt, or rotary motion. Their rapid availability enables users to swiftly respond to evolving requirements and stay competitive.
