Motor Speed Measuring Sensor Motor Shaft Encoder (HC-020K)

HC-020K speed measuring sensor is a wide voltage, high resolution, short response time, and the switch output speed measurement module.
It can test motor’s rotational speed with black encoder (measured spec.
is related to the encoder, the inner diameter of D type encoder that provided is 4mm, can be used for motor output shaft w/ 4mm diameter, which is TT motor we matched, yellow shell and white axis).
