Installation & Maintenance
Ensure the application shaft matches the 8mm semi-hollow shaft for seamless coupling.
Carefully align the encoder to prevent shaft misalignment and reduce wear. Flexible couplings are recommended.
Secure the encoder housing firmly using mounting screws to avoid vibration.
Connect power supply within 5 to 24 V DC, adhering to polarity and wiring diagrams for your output type.
Use shielded cables for signal wires to minimize electromagnetic interference.
Periodically clean the encoder surface to prevent dust accumulation.
Routinely inspect wiring and connectors for tightness and signal stability.
Replace encoder if signal loss or mechanical damage is detected.
