Features

CHM9, 90mm SSI absolute single turn encoders:

  • Especially designed for heavy-duty (steel, paper, wood – mills, cranes…) Compact and robust conception. Excellent resistance to shocks/vibrations and to extreme axial/radial loads.
  • Solid shaft 11mm and 12mm.
  • High protection level IP65 – IP67 option.
  • High performances in temperature –20°C to 90°C.
  • Universal power supply from 5 to 30 Vdc – SSI output.
  • High resolutions possibility, up to 16 bits (Gray or binary).
  • Standard DIRECTION and RESET input.
  • Digital or sine incremental outputs option.
