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 400 PPR 2-Phase Incremental Optical Rotary Encoder at a competitive price.
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 built to Industrial grade.
The Encoder comes with a Standard 1.5 m cable length which can be extended with extra cable if needed.
Adding a pull-up resistor to both the 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 the 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.
Note: A sample tutorial code has been given in the Attachments Section.
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 the 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 interference and precise encoder output.
