WMYCONGCONG 8 PCS KY-040 360 Degree Rotary Encoder Module Brick Sensor Board with Knob Cap for Arduino Micro Controller Use

• The rotation counts are not limited, designed with continuous 360 degree rotation sensors.
• Working voltage: 5V
• Material: Electronic components + PCB
• Reset to its initial state with the buttons on the rotary encoder, starts counting from 0.
• Designed with detent and push button switch feature, comes with nuts and washers, suitable for Arduino micro controller use.

Specification: KY-040 Module: Working voltage: 5V Pulse circle: 20 Material: electronic components + PCB Size: 26 x 19 x 29mm/1.02 x 0.75 x 1.14inch Diameter of the thread: 7mm/0.27inch Height of the thread: 7mm/0.27inch Knob Cap: Diameter: 15mm/0.59inch Height: 16.5mm/0.65inch Connection: "GND”: ground terminal "+”: 5V power supply "SW”: 'Select' switch (activated when shaft pressed on top) "DT”: Encoder Pin B "CLK”: Encoder Pin A Designed with detent and push button switch feature, comes with nuts and washers, suitable for Arduino micro controller use. 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. How it works: incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors. Package Content: 8 pack KY-040 rotary encoder module(knob, nut, washer included)
