Absolute encoder WV58MR

Absolute redundant safety rotary encoder

open expert video
The WV58MR rotary encoder is a magnetic Safety rotary encoder with redundant position detection, custom-designed for use in mobile machines. It can be employed in safety-critical applications up to Performance Level PLd. Thanks to its particularly robust design of an optional redundant CANopen or CANopen Safety interface it is ideally suited for heavy-duty use in mobile machines.Combined with wire-actuated encoders, the WV58MR can als be used for reliable linear position monitoring.

Profile WV58MR:

  • Absolute redundant safety rotary encoder
  • Interface CANopen Safety or CANopen redundant
  • Suitable for applications up to Performance Level PLd
  • Salt-spray resistant housing available
  • High electro-magnetic compatibility
  • Available with special swing ring functionality
  • With PURE.MOBILE technology
CANopen Functional Safety PLd CANopen Safety PURE.MOBILE E1
