Rotary Angle Encoder Module
EGP 45
See other suppliers →Description
The rotary angle encoder module is used to measure both angles and RPM. The Rotary encoder is an incremental encoder as has no limit for number of counting (This way it is different than potentiometer). It can also detect clockwise and counter clockwise rotation and that’s why it has 2 pins for detecting rotation. Basically, it translates the rotary motion into a sequence of pulse signals. By comparing the square wave generated from each of the two pins you can determine the direction of rotation. and by counting the number of pulses you can determine both the rotation angle and the RPM of the rotating shaft. Features Operating Voltage: 3- 5V NOF pulses per Cycle: 20 pulses NOF Cycles: unlimited Rotation Direction Detection: clockwise and counter clockwise Dimensions: 32 x 15 mm Rotary encoder datasheet and connection tutorial Rotary encoder tutorial with arduino
