The fast availability of PI’s actuators enables design engineers to respond quickly to new project requirements, the company said.
AUBURN, Mass.—Motorized high-resolution actuators from PI (Physik Instrumente) are reported to provide reliable, high-precision motion in a compact design for applications that require sub-micrometer precision.
PI’s L-220 series linear actuators are engineered for demanding tasks in optics (optical alignment), precision automation, photonics, semiconductor testing, metrology, and microscopy. Select models are available with short lead times to support fast system integration, the company said in a release.
According to PI, the actuators combine precision and force in a compact form factor. Offering travel ranges from 13mm to 77mm (½ inch to 3 inches) 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,” the release stated. This is said to ensure accurate, repeatable motion.
Available with closed-loop DC servo or stepper motors, the L-220 linear 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. They are also available for vacuum environments up to 10-6 hPa and for cleanroom applications, the company said.
“Used worldwide—from semiconductor fabs to optical labs—L-220 micro-positioning actuators provide precision motion, repeatable 100nm steps, and high reliability,” the release stated. “With fast availability, they enable design engineers to respond quickly to new project requirements and maintain a competitive edge.”
In addition to semiconductors, optics, and photonics, the actuators have applications in industries such as laser processing and medical technology, the company said.
