Here is a quick look at how contactless potentiometers work, where they are used, and why they are gaining ground.

How optical rotary encoders can provide real-time motion feedback on motion applications using stepper motor-driven linear actuators. Stepper motor linear actuators with added optical encoders (From ...

Add a description, image, and links to the shaft-encoder topic page so that developers can more easily learn about it.

60 OPTICAL SHAFT ENCODER FROM SHARP T. Wigmore source: Sharp Electronics An optical shaft encoder is an electronic device used in applications where the position or speed of a rotating shaft needs to ...

A rotary encoder is a type of electromechanical position sensor that can be used to identify the angular position of the rotary shaft. This type of sensor or module generates an electrical signal ...

If you have a motor and you’d like to know where the shaft position is, you are likely to turn to an optical encoder scheme. However, as [lingib] points out, you can also use a magnet and a ...

Abstract: A low-frequency angular acceleration rotary table (LFAART) is capable of sinusoidal motion around a fixed position and essential to verify dynamic characteristics of a gyroscope device. The ...
