The most compact member of LAB’s RT-S series. The RT075S delivers all the precision and agility you’ve come to know from LAB, and captures this technology in a highly miniaturized design. In true spirit of its compact predecessor (RT100S) this new rotary stage is even lighter and more compact, but still has the same qualitative advantages as its bigger brother.
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.
