Tegg 2 PCS KY-040 360 Degree Rotary Encoder Module Brick Sensor clickable Switch with Knob Cap for Arduino

Description: Type: KY-040 Rotary Decoder Encoder. Operating Voltage: 5V. One round number of pulse: 20. Width: 19mm/0.75 Inches. Length: 30mm/ 1.18 Inches. Height: 28mm/1.10 Inches. Material of Knob Cap: Aluminium Alloy. Diameter of Knob Cap: 14mm/ 0.55 Inches. Height of Knob Cap: 17mm/ 0.67Inches. Package:2 PCS. Pin description: CLK - equivalent to output A in regular encoder. DT - equivalent to output B in regular encoder. GND - equivalent to output C in regular encoder. SW - reset switch. + (VCC) - positive supply to the unit. The KY-040 rotary encoder is a 360 degree rotary input device (i.e. a control knob) that provides an indication of how much the knob has been rotated AND which direction it is rotating in. It is a great device for stepper and servo motor control. You can also use it to control devices like digital potentiometers. It is ideal for navigating menus on a display or taking inputs such as numbers or text characters. The range of input can be easily defined and mapped in software. A push button switch is built into this encoder. If you push on the shaft, the normally open switch "SW" will close. This can be used as an On/Off switch, to change control functions, ranges, selecting a menu item or entering a number. The "D" shaft of the encoder can be fitted with a knob for using it in a product.

• Type: KY-040 Rotary Decoder Encoder.
• Operating Voltage: 5V. One round number of pulse: 20.
• Size: 30x19x28mm/1.18x0.75x1.10 Inches(LxWxH). Package:2 PCS.
• Unlike rotary potentiometer count, the rotation counts are not limited.
• With the button on the rotary encoder can be reset to its initial state, that starts counting from 0.
