Orange 600 PPR ABZ 3-Phase Incremental Magnetic Rotary Encoder

This is a Orange 600 PPR ABZ 3-Phase Incremental Magnetic Rotary Encoder.

If you want to build a project where the machine can control the speed of the conveyer belt as well as the direction of movement, a rotary encoder is a must-have component. Keeping this in mind, Robu.In is introducing the brand new orange 600 PPR ABZ 3-Phase Incremental Optical Rotary Encoder at a competitive price.

A rotary encoder is a type of position sensor which is used for determining the angular position of a rotating shaft. It generates an electrical signal, either analog or digital, according to the rotational movement.

Orange 600 PPR Incremental Magnetic Rotary Encoder is a hi-resolution magnetic encoder with quadrature outputs for increment counting. It will give 2400 transitions per rotation between outputs A and B. whereas the Z phase will produce one transition per rotation. A quadrature decoder is required to convert the pulses to an up count. The Encoder is built to Industrial grade.

  //Do stuff here

  Serial.println(encoderValue);

}


void updateEncoder(){
  int MSB = digitalRead(encoderPin1); //MSB = most significant bit
  int LSB = digitalRead(encoderPin2); //LSB = least significant bit

  int encoded = (MSB << 1) |LSB; //converting the 2 pin value to single number
  int sum  = (lastEncoded << 2) | encoded; //adding it to the previous encoded value
