Heat-resistant bottom-mount type for general-purpose


  • Designed for use in high-temperature environments, no need for applying air- or water-cooling

  • The outer dimensions and output signal of these encoders are compatible with the RP-110 series.

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

  • On request, an oil seal can be fitted to the rotating shaft, making this encoder waterproof (IPX5 applicable.)

  • Usable in on-site installation and for long distance transmission
