Application Scenarios

  • High-precision industrial motor speed and position control

  • Robotics requiring fine motion control and feedback

  • Conveyor systems in packaging and manufacturing lines

  • CNC machines for accurate cutting and positioning

  • Printing machinery for synchronized roller and sheet control

  • Automated assembly lines requiring reliable rotary feedback

Installation & Maintenance

  1. Ensure the application shaft matches the 8mm semi-hollow shaft for seamless coupling.

  2. Carefully align the encoder to prevent shaft misalignment and reduce wear. Flexible couplings are recommended.

  3. Secure the encoder housing firmly using mounting screws to avoid vibration.

  4. Connect power supply within 5 to 24 V DC, adhering to polarity and wiring diagrams for your output type.

  5. Use shielded cables for signal wires to minimize electromagnetic interference.

  6. Periodically clean the encoder surface to prevent dust accumulation.

  7. Routinely inspect wiring and connectors for tightness and signal stability.

  8. Replace encoder if signal loss or mechanical damage is detected.
