Hi,
as part of a project I needed a slim (<10mm) small diameter (<30mm) through hole absolute encoder that works at 100 degC. I wanted this to be able to determine a motorized valve position, so it needed to slip onto the gearbox output shaft between the motor and the valve.
Anyway, I couldn't find anything on the market, so I designed and built my own. I'm wondering if this would have a market in its own right? Being slim, you simply slip it onto the output shaft of a motor and it gives you an absolute angular position in 7 bit parallel digital form. The version I have made is 7 bits, so about 3 degrees resolution. If you have an incremental encoder at the other end of the motor, you can use this to improve the resolution, or, alternatively, I have designs for higher bits. Cost to build is under $50.
Given there's nothing on the market that I could find, maybe this is too esoteric - anyone out there know if this would be useful?
