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

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 ...

Why are there so many different angle encoders on the market? Why do they use different scanning and measuring methods? And which one should a designer choose? To answer those questions, engineers at ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...
