Datasheet Summary
DIGITAL OPTICAL ROTARY ENCODER
Wiring:
Green = A phase White = B phase Red = Vcc positive power supply Black = V0 (Ground) Another metal shielding layer interference.
Output:
AB two-phase quadrature output rectangular pulse, the circuit output is NPN open collector output type
This type can be output with internal pull-up resistor available in Arduino, microcontrollers or PLC, such as Atmega, pic, 51 or microcontroller Mitsubishi PLC.
If Internal Pullup is not available, then you need to Pull-up Output Channel A & B with resistors supplied with product. i.e. resister between Green and RED, White and RED wire.
