The sensing mechanism in an incremental optical rotary encoder consists primarily of a light source, code wheel, and optical detector. As the code wheel turns, a ring of alternating opaque and ...

LSI Computer Systems (LSI/CSI) has created a family of 63 tap (6bit) digital potentiometers for direct connection to quadrature decoders, push buttons, GPIOs or SPI serial controls. Debounce circuits ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

Reading quadrature encoder signals at high speeds (e.g., 1MHz, or, 1m/s with a resolution of 1µm) often requires dedicated hardware. This Design Idea shows a simple scheme to accomplish this function ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...

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 ...
