Instructions

1. Power Supply:

   • Connect the encoder to a 5 V DC power supply.
   • Ensure the supply voltage is stable to avoid erratic behavior.

2. Installation:

   • Mount the encoder on a flat surface using the through-hole mounting method.
   • Ensure the shaft is aligned with the intended axis of rotation.
   • Secure the encoder with appropriate fasteners to prevent vibration-induced loosening.

3. Wiring:

   • Connect the red wire to the positive terminal of the power supply.
   • Connect the black wire to the ground (GND).
   • Connect the yellow and green wires to the A and B output channels, respectively, for quadrature encoding.
   • Optionally, connect the white wire to the index channel if required.

4. Operation:

   • Rotate the shaft to generate pulses on the A and B channels.
   • The A and B signals will be phase-shifted by 90 degrees, allowing for direction detection.
   • The index channel (if used) will provide a single pulse per revolution for reference.

5. Handling:

   • Handle the encoder with care to avoid damage to the shaft or housing.
   • Avoid exposing the encoder to extreme temperatures or humid environments.
   • Do not apply excessive force to the shaft during installation or operation.

6. Troubleshooting:

   • If the encoder does not produce output, check the power supply connections and ensure the supply voltage is correct.
   • Verify that the wiring to the A and B channels is correct and secure.
   • If the output is erratic, check for mechanical issues such as misalignment or loose mounting.
