How to put together an HKT30 optical rotary encoder? I'm working on a project involving stepper motors. It is important for this project to track the position of these motors, so I decided to buy an optical rotary encoder, specifically an HKT30(HKT3005-C03G-1000B-5E) pictured here. I've found it difficult to find resources on how to put this together. I've found datasheets, like this one, but it does not seem to be made up of the same components I have. I think I've basically gotten the gist of how one puts this together from google images, but I would like to be pointed in the way of an explicit resource in case I damage my parts.
Additionally, I was hoping for an explanation on the 5 wires (red, green, black, white, and gray), their purpose and how to set one up on a board.
If any clarification or images are needed, I would be happy to provide.
Thank you!
It's not hard...

The sensor screws into the screw holes.
The disc slots into the gap in the sensor
The case clips on the outside

As to what the wires are, only the datasheet / manual / manufacturer can tell you that. Maybe if you trace them on the sensor board you can work out what is what.
