Absolute encoder WV42HD

Heavy-duty absolute rotary encoder

Magnetic absolute multi-turn rotary encoder in heavy-duty stainless-steel design – batteryless, robust and flexible. The WV42HD is predestined for demanding measuring jobs in the heavy-duty area owing to its extremely robust housing, its bearings, which are designed to tolerate high radial and axial loads as well as its high resistance against external impact.

Profile WV42HD:

  • Heavy-duty design in stainless steel

  • Compact design (42 mm diameter)
  • IP69K, IP68 protection category
  • Resistant to salt spray and acids

  • CANopen interface, SSI, analog
  • Multi-turn without battery
  • High shaft loadability of up to 270 N

  • 16 bit mult-iturn (65536 revolutions)

  • 12 bit single-turn (4096 steps)
