6 Sets KY-040 360 Degrees Rotary Encoder Module Brick Sensor Switch Development Board with 17x17 mm with Knob Cap

Description: Rotary Encoder Module Specification:Working voltage: 5V; One round number of pulse: 20 These pulses brick sensor are used to control the angular displacement. Rotary Encoder Module with the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0. By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer counter,which species rotation counts are not limited. In Eltra angular displacement encoder conversion using a photoelectric scanning principle. The conversion of the angular displacement in the Eltra encoder uses the principle of photoelectric scanning. The rotary encoder can count the number of pulse output during rotation in the positive direction and reverse direction through the rotation and this rotation counts are not limited. Knob Cap specification: Material: Aluminum alloy Color:Black Package include:6pcs rotary encoder module+6pcs Aluminum Knobs Rotary Switch Potentiometer Volume Control Pointer
