Absolute encoder WH58MR

Absolute redundant safety rotary encoder

open expert video
The WH58MR rotary encoder is a magnetic safety rotary encoder with redundant position detection and hollow shaft, which has been specially developed for use in mobile machines. It can be used in safety-critical applications – up to performance level PLd.  Thanks to its particularly robust design, an optionally redundant CANopen or CANopen Safety interface, it is ideally suited for tough conditions in mobile machines.

Profile WH58MR:

  • Absolute redundant safety rotary encoder
  • Interface CANopen Safety or CANopen redundant
  • Suitable for applications up to Performance Level PLd
  • Hollow shaft to ø 15 mm
  • Salt-spray resistant housing available
  • High electro-magnetic compatibility
  • IP67 protection category
  • With PURE.MOBILE technology
