More info

The KY-040 360° Rotary Encoder is a rotary input device (as in knob) that provides an indication of how much the knob has been rotated AND what direction it is rotating in. It is a great device for stepper and servo motor control.

The KY-040 rotary encoder is an incremental electro-mechanical device that converts the angular position or motion of a shaft or axle to digital code. The output of incremental encoders provides information about the motion of the shaft, which is typically further processed in processor / controllers into information such as speed, distance, and position.


  • 360° infinite rotation.
  • Shaft Diameter - 6mm, D Shaped
  • 5 Pin - GND, Power - 5V, SW - Push switch connection, DT - Direction, CLK - Clock
  • Can be used to detect clockwise and anticlockwise directions
  • Compatible with Arduino
