The UPR-270 Air features best value for wobble and flatness and one can reach high accuracy because of high-precision air bearing. All rotation stages UPR-270 AIR are directly driven by a torque motor ...

My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.

PI announces the launch of the V-625 direct drive rotation stage, a high-performance rotary positioning and scanning stage designed for applications requiring smooth, high-precision rotary motion.

Rotary encoders are electromechanical devices used for sensing in myriad applications—on motors paired with drives and automated machinery for everything from consumer electronics, elevators, and ...

This application note demonstrates how to read data from the two-channel output of an incremental rotary encoder. Data from these two channels are based on the Gray Encoding System and can be used to ...

Multiturn absolute encoders resemble any absolute encoder where light shines through an etched disc that has a combination of ON and OFF signals. resemble any absolute encoder where light shines ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

Similar in size and shape to the common panel-mounted potentiometer, the incremental rotary encoder provides an inexpensive ‘digital’ alternative to the analog potentiometer. It is typically used to ...
