This robust heavy-duty rotary stage distinguishes itself from the competition by its direct drive integration, unseen in this class of size, and by its exceptionally low error motion. A high-resolution encoder system enables for an ultimately stable positioning and velocity tracking. Imagine a stage that takes the weight of a city car, and rotates this payload with an error motion below a thousandth of a human hair!
LAB’s RT-S series is your go-to choice when looking for rotary air bearing stages with superior error motion performance, high stiffness and high load-carrying capacity! The low-profile design of the RT-S series houses a top-class air bearing, motor and encoder which enable excellent angular positioning and velocity stability. A large through hole facilitates slip ring integration, optical or other feedthrough for specific applications such as x-ray and optical inspection.
This rotary stage can be supplied with motion driver and software. The software offers an easily programmable positioning loop, automatic homing procedure and communication with your machine interface. An emergency procedure to generate a safe stop when pressure supply fails is integrated. Additionally, a graphical user interface decreases the setup-time to a minimum.
