High Speed Piezo Linear Stage, 48 mm Travel, Direct Encoder, Integrated Controller

The CONEX-SAG is an ultra-compact and cost-effective single axis motion controller. The controller comes with the CONEX GUI, simple and intuitive to use and conveniently accessible via USB, which also supplies power to the controller. It offers a closed-loop algorithm which is a simplified version of the typical DC servo loop control, and combined with the linear encoder, provides a system bi-directional repeatability of 25 nm. For in-position stability, the user can adjust the deadband parameter that stops dithering when the stage is within a set position tolerance. And for a more economic option, open-loop CONEX-SAG-LS stages are also available without an encoder. RS232 connectivity is standard starting with products manufactured in September 2025 and later. A CONEX-SAG-RS232 Cable (sold separately) will be required to connect with the RS232 port.

A graphical user interface (GUI) allows interaction with the CONEX-SAG Controller. Through the GUI, a user can initiate moves, change the state of the controller, adjust parameters and perform other functions. The CONEX-SAG Controller GUI runs on Windows 7, 8 and 10 platforms.

The linear stages of the CONEX-SAG-LSxx feature an innovative miniature direct read linear encoder in the (P) models. The footprint is very small while delivering sub-micron bi-directional repeatability expected from direct read encoder technology. 

In terms of size, the CONEX-SAG controller is comparable to a deck of cards, only measuring 93 x 53 x 23 mm. Six controllers can fit on a baseplate. The stages are also designed to easily stack as XY stage, without requiring an adapter plate, resulting in only 24 mm height. Both controller and stage are compact and ideal for space-confined or access-limited applications.

The full stainless steel body of the CONEX-SAG-LSxx allows for a more compact design with exceptional stiffness-to-weight ratio, greater thermal stability, and high load capacity.
