In a recent email, Julian Lana-Sarrate, an independent embedded designer, described a good method for confirming the operation of a rotary encoder using a rising edge-count measurement. He included ...

A lot of people have used brushless or stepper motors as rotary encoders, but they all seem to do it by using the motor as a generator and looking at the phases and voltages.

The product line includes linear scales, rotary and angular encoders, digital readouts, digital length gages, CNC controls and machine inspection equipment.

There are many ways you can read a rotary encoder. Some are probably better than my method. Also, these cheap mechanical encoders are terrible.

Adafruit has made an I2C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style) ...

Rotary and linear optical encoders are common in position and motion sensing. Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque ...

Encoder technologies abound, but software, wiring, and embedded microprocessors let designers tailor magnetic-encoder performance to application requirements.

HEIDENHAIN is meeting the market demand for high-speed, high-resolution modular rotary encoders for motion feedback with the launch of the ERO 2000 series encoder.
