Optical Encoder Set for DC Gear Motor
This is a 2 channel optical encoder set what fits perfectly with our 2WD and 4WD robot platforms! This kit will help you monitor the speed of the motors. This encoder set uses the HC-020 to optically sense the rotation of the circular grid board which will output a square wave signal. There 20 grids on the circular grid board, so each rising/falling edge standing an angle of 18 degrees.
