Parametric Rotary Encoder Gray and Natural Code

thingiverse

It's a parametric absolute angle encoder using the Gray code or binary natural code. The encoder has several main parameters that can be defined: number of bits; length of cells; first cell radius; axis size. I also provided a reader compatible with a disc and some common phototransistor packages T1 e T1 3/4 (for example SFH309 or SFH313). Update Bug Fix 04/02/2017 Changed Reader, added NEMA17 support, improved phototransistor mount. New example code. To assemble on a pinion: Insert the driveshaft; insert the reader module (emission); insert the encoder disk; insert the reader module (reading); merge the two player modules through the coupling module with two M3 nuts in the intended cavity and then secure them with their M3 screws; constrain therefore the module and attached to the structure where the engine. The Reader is easily customizable for other phototransistor / photodiodes. I explicitly provided a function that defines the size of the cell in which it will be put. Adding to that function the size of the BJT to be used. For mounting on a pinion: Insert the driveshaft; insert the reader module (emission); insert the encoder disk; insert the reader module (reading); merge the two player modules through the coupling module with two M3 nuts in the intended cavity and then secure them with their M3 screws; constrain therefore the module and attached to the structure where the engine.
