A small tip:
Encoders come in various types, each suited for different applications based on their functioning and output characteristics. Here’s a breakdown of the two main categories and some additional types:
By Output Type: Incremental Encoders and Absolute Encoders;
By Sensing Technology: Optical Encoders and Magnetic Encoders.
Overall Size

Motor 4 Leads Connection: A+(Black), A-(Green); B+(Red), B-(Blue)
Encoder 8 Leads Connection: A+(Black), A-(Blue); B+(Yellow), B-(Green), Z+(Brown), Z-(Grey), 5V(Red), GND((White)
If your drive controller don’t support Z signal, then you can leave Z unconnected.
