Primatics PLG160

Speak with an Expert


The Primatics PLG160 Series positioning stage is the mid-size entry of our all-purpose PLG series stages. The PLG160 is ideal for high precision alignment and attachment, offering unparalleled flexibility—our design allows the user to fit a high performance product into a vast array of applications.



The Primatics PLG160 linear motor stage is ideal, both from a design and functionality standpoint—the compact design makes it one of the smallest linear motor stages on the market and its brushless motor provides exceptionally smooth motion. Additionally, the unique Prima-Flex cabling system and Prima-Seal enclosure system allows for sensitive parts (encoder and sensor circuits, for example) to be self-contained and protected from contamination and harsh environments. Encoder resolutions up to 0.1 microns are standard.

An ideal solution when overall size is a concern, the PLG160 frameless motor mounts directly onto the ball screw—this eliminates the need for a motor coupler and external motor, ultimately reducing the footprint of the positioner while maintaining accuracy and dynamic response.


The inline version of the PLG160 accepts standard Imperial, NEMA 23 frame step and servo motors with ¼ inch, ⅜ inch, 8 millimeter, and 9 millimeter shafters—because the motor mount is designed so its lower surface stays inside the cross-section of the positioner, the PLG110 eliminates any need for an additional plate to be installed under the base.


All PLG stages are available with a high flow purge option to help keep to the internal mechanics particle-free—carriage-spanning tabletop options are also available for ball screw motor drives.


All PLG160 performance specifications are verified with a laser interferometer system, and a full set of accuracy, repeatability, straightness and flatness plots are included with each stage. Additionally, each unit undergoes extensive burn-in and testing—these steps ensure that the stage will deliver optimal performance over a long period of time.
