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.
- Heavy-duty design in stainless steel
- Compact design (42 mm diameter)
- IP6K9K, IP68 protection class
- 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)
- 13 bit single-turn (8192 revolutions)
