I removed this optical encoder from a printer to use in a project but I don't know how to connect it, can anyone help me?
Can you post a close in picture of the sensor itself? Most have a bit of identifying markings ;
like this slot sensor. This will usually allow you to at least identify which side is emitter and which is detector.
It does not have any other markings on its body (other than those shown in the first photo), and these are the markings on the PCB seen from above
My guess would be:
[o] +5V
(o) Output A (o) LED+
(o) Output B (o) LED-
(+) Ground
The Output pins might be "Open Collector" and need INPUT_PULLUP pins. The LED pins might need a series resistor to limit current.
