Linear Actuators for Micropositioning and Precision Alignment – Now Available with Fast Delivery
High Precision Actuators with Stepper Motors and Servo Motors
Auburn, MA — 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.
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 to 77mm 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 and stepper motors, these actuators reach speeds up to 30mm/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.

Featured Product
3D Vision: Ensenso B now also available as a mono version!
This compact 3D camera series combines a very short working distance, a large field of view and a high depth of field - perfect for bin picking applications. With its ability to capture multiple objects over a large area, it can help robots empty containers more efficiently. Now available from IDS Imaging Development Systems. In the color version of the Ensenso B, the stereo system is equipped with two RGB image sensors. This saves additional sensors and reduces installation space and hardware costs. Now, you can also choose your model to be equipped with two 5 MP mono sensors, achieving impressively high spatial precision. With enhanced sharpness and accuracy, you can tackle applications where absolute precision is essential. The great strength of the Ensenso B lies in the very precise detection of objects at close range. It offers a wide field of view and an impressively high depth of field. This means that the area in which an object is in focus is unusually large. At a distance of 30 centimetres between the camera and the object, the Z-accuracy is approx. 0.1 millimetres. The maximum working distance is 2 meters. This 3D camera series complies with protection class IP65/67 and is ideal for use in industrial environments.
