High Speed Piezo Linear Stage, 32 mm Travel, Open Loop, 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.

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.
