This is a 400 PPR resolution optical rotary encoder with quadrature outputs for increment counting. It will give 1600 transitions per rotation between outputs A and B. A quadrature decoder is required to convert the pulses to an up count. The Encoder is build to Industrial grade.
The Encoder comes with Standard 1.5 m cable length which can be extended with extra cable if needed.
- Adding a pull-up resistor to both A and B phases of the encoder output will help to avoid the effect of interference in output and get the precise logical output value from encoder at the same time.
- Also adding a pull-up resistor to all phase output lines protects the open collector output-triode from damage due to direct Vcc supply short circuit.
Power and Input Terminal Assignments:
|Terminal Name||Wire Color||Description|
|Phase A||White||Quadrature encoded output A|
|Phase B||Green||Quadrature encoded output B|
|VCC||Red||VCC should be connected to +ve 5V of supply|
|GND||Black||The ground should be connected to negative of the supply|
|Shield||Golden||The shield should be connected to GND|
Shielding is important. At a minimum, the cable should be protected either by a foil jacket with a drain wire or by a braided-wire shield that is grounded. For very sensitive applications or high-EMI environments, foil jacketed wires in combination with an overall braided-wire shield around the cable should be used to avoid the interference and precise encoder output.
