Installation & Maintenance

  1. Clean the mounting area and verify compatibility with the 6mm shaft diameter.

  2. Align the encoder shaft carefully with the driven equipment shaft; flexible couplings are recommended to minimize stress.

  3. Secure the encoder firmly using the mounting holes to prevent vibration during operation.

  4. Connect the power supply (5-24V DC) and ensure correct wiring for your selected output type.

  5. Shield signal cables to prevent electromagnetic interference and ensure stable signal transmission.

  6. Perform periodic inspection for dust accumulation and clean the encoder surface gently without harsh chemicals.

  7. Check connector and cable integrity regularly to maintain signal quality.

  8. Replace encoder if signs of mechanical wear or signal inconsistencies appear.
