Piezo Motor Rotation Stage, 1 in., Direct Encoder, Includes Controller

The CONEX-AG-PR100P is a piezo motor rotary stage with direct encoder feedback and closed-loop piezo motor controller/driver. Initially targeted for repeatable positioning of polarizing optics, it can also be used as a miniature rotation stage for precision positioning of other optics or lightweight samples.
The Agilis AG-PR100P rotary stage comes with a built-in direct read encoder, enabling high angular position repeatability. The footprint is maintained while delivering 0.002° uni-directional repeatability expected from direct read encoder technology. The rotary stage is very compact, but is capable of 340° travel, and 0.001° MIM.

The CONEX-AGP closed-loop algorithm is a simplified version of the typical DC servo loop algorithm, and combined with the rotary encoder, provides a system uni-directional repeatability of 0.002°. For stability in-position, the user can adjust the dead band parameter that stops dithering when the stage is within a set position tolerance.


The CONEX-AGP is a very compact and inexpensive single axis motion controller and is delivered already pre-configured for the stage.
For OEM applications, an optional retainer to secure the USB and power cables is available. In addition, RS232 and RS485 communication is available at the board level.
