Bottom-mount Industrial type for general-purpose


  • Excellent resistance to shock and shaft loading

  • Selectable for either AC or DC operation

  • Output connection can be selected from a terminal strip or a connector.

  • Upon a request, reinforced type can be provided whose allowable shaft loading is increased.

  • Upon a request, an oil seal can be fitted to the rotating shaft, making this encoder applicable to IP65 protection class. (when selected terminal strip as an output connection)

  • Ideal for on-site installation and long distance transmission

  • ”Noise immunity” circuit prevents power noise and erroneous signal generation caused by small vibrations.
