Pick The Right Encoder–And Save Big On Rotary Stages

The DDT100 Series, our most compact rotary stage, now features new encoder options that can reduce its price by as much as one third. The optional encoders, which can be found on stages with the new DDT100LC designation, are optical code wheels offering either 20,000 or 40,000 counts/rev, or 0.3 and 0.15 mrad respectively.

Those resolutions are not as fine as our standard DDT100R models, which still ship with high-end Renishaw optical ring encoders capable of resolutions down to 2 μrad.

While some applications do need every bit of the resolution available on the DDT100R, the DDT100LC’s code wheels offer more than enough resolution for many motion jobs. For example, the first application for our new encoder option involves the positioning of a turret on a biomedical machine that had a low cost and small package requirement.
