NEMA 8 closed loop stepper motor has frame size 20-38mm , equipped with a 1000cpr incremental optical encoder, has a rated current of 0.6A and a holding torque of 0.04Nm. This NEMA 8 closed loop sepper motor offers higher accuracy, higher output torque, higher speed, lower motor heating, lower power consumption, and faster response to drive controllers compared to open loop stepper motors. If you still don’t have a stepper drive for this model, we high recommend: Leadshine CL42C Closed-Loop Stepper Motor Drive Controller 20-50VDC 0-3.0A

A Small Tip:
An optical encoder is a sensor device that translates motion, typically of a shaft or a linear path, into electrical signals. It uses light to detect movement and provide feedback on position or speed.
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.
