Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists have developed a first building block for photonic 'transistors' ...

A quadrature encoder uses two output channels offset in phase to detect both direction and position with greater precision.

Optical encoders are critical components in systems with rotating shafts or parts. Optical rotary encoders are the most widely used way to transform mechanical rotary motion into electrical signals.

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by 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 ...

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 ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

Rotary encoders provide critical information about a motor shaft’s position, rotational direction, velocity (rpm), and acceleration. They are vital components in motion-control feedback loops used in ...
