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 ...

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 ...

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 ...

A rugged, self-contained, resolver-based encoder, the Shaft-Tracker from Computer Conversions Corp. can replace less reliable optical shaft encoders. The device provides both incremental and true ...

Tachometers directly report angular speed. Some are simple processors that merely digest output from an external sensor or encoder; others are integrated units that combine an encoder or sensor and a ...

Featuring a new shaft coupling that provides mechanical fault exclusion for connection to the user’s machine shaft, the encoders are of particular use in safety-related applications up to SIL 2 PL d ...

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 ...

Continuing his tradition of making bits of wire and scraps of wood work wonders, [HomoFaciens] is back with a unique and clever design for an electromechanical encoder. There are lots of ways to build ...
