Siko WH58MR Absolute encoder
Product Information
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.
- 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 class
- With PURE.MOBILE technology
