Many motors offer a quadrature encoder that give feedback on whether, and in which direction, the motor shaft is moving. But if you’re clever about analyzing the data you can use a quadrature encoder ...

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 ...

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 ...

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 ...

A high-speed quadrature encoder module provides simultaneous input and decoding for up to eight incremental quadrature encoders at resolutions of 16, 32, or 48 bits. The USB-QUAD08 data acquisition ...

The LS7566 24-bit four-axis quadrature counter provides an efficient interface for up to four incremental encoders. The encoder inputs are digitally filtered for elimination of noise and errors ...

Shaft motion can be tracked by incremental encoders for analysis and use by system controls downstream. Rotational direction is monitored with an encoder disc paired with simple electronics and a dual ...

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 ...

Everyone has at least one extra mouse laying around; why not get some use out of it? Disassembling the mouse you can get two optical encoders plus four infrared emitter/detector pairs. Then you can ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...
