Is it really possible to build a rotary encoder out of a flattened tin can and a couple of photodetectors? Sure it’s possible, but what kind of resolution are you going to get from such a contraption?

Motion-control or industrial automation system designers who need to measure the rotation of shafts or other mechanical components can typically choose from two types of rotary encoders. Encoders ...

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 ...

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 ...

Two new rotary units deliver high-speed precision positioning, and their rugged designs promise long life. Hardinge's DD200 rotary has high speed, high torque and high precision positioning. The new ...

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 ...
