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?

[Pete] needed a rotary encoder for one of his project so he set out to build his own. As the name implies, a rotary encoder measures rotation by encoding “steps” into electrical signals which can be ...

Rotary encoders connect to a shaft and, as the shaft rotates, the encoder outputs pulses. These are used to determine the speed of the object. By counting the amount of pulses per one full turn of the ...

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 ...

This application note demonstrates how to read data from the two-channel output of an incremental rotary encoder. Data from these two channels are based on the Gray Encoding System and can be used to ...

The AS5140H is presented as the industry’s first 10-bit magnetic rotary encoder IC fully qualified for ambient temperatures to 150°C. Offering a 0.35° resolution, the encoder’s high temperature rating ...

Pepperl+Fuchs introduces its newest innovation, the ENI58IL rotary encoder with BlueBeam Technology. Pepperl+Fuchs introduces its newest innovation, the ENI58IL rotary encoder with BlueBeam Technology ...

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) ...

Same Sky has created an absolute encoder family for motor shafts from 9 to 15.875mm (5/8inch). Called AMT25 and said to be accurate to ±0.2°, the family relies on the same in-house capacitive ASIC for ...

Anyone searching for a way to connect multiple rotary encoders on the I2C bus, may be interested in a new piece of hardware created by Simone based in Turin, Italy. The aptly named I2C Encoder V2 ...

The AS5050 10-bit magnetic rotary encoder integrates automatic power-down and wake-up modes. On a single chip, it hosts four Hall elements, a 10-bit angle encoder, smart-power-management controller, ...
