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 ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

Optical rotary encoders are the most widely used way to transform mechanical rotary motion into electrical signals. There are three basic configurations for optical encoders: incremental, absolute, ...

Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...

For any designs that deal with large motors, isolation is a desired characteristic for both control and sense loops. Turn on, turn off, changes in load, changes in power, and unexpected events can ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...
