I needed a rotary encoder — I pulled a cheap one out of one of those “49 boards for Arduino” kits you see around. Not the finest encoder in the land, I’m sure, but it should do the job.

Spinning the rotary encoder cycles through a menu of programs on the 16×2 LCD, and the key map just updates automatically for the chosen program.

This means that solid-state rotary measurement technology is for the first time able to replace unreliable rotary encoders without any need for new software programming in existing designs ...

Versions with PROFINET interface are new to the HEIDENHAIN rotary encoder program. These encoders support the functions of Conformance Class 4 (full scaling and preset functions) and offer ...

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.
