Siko WH58MR Absolute 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 single-turn rotary encoders

Single-turn rotary encoders are angle encoders, which are able to absolutely acquire and output the position within one revolution (360°. These encoders are particularly suited for applications where a swivel movement is to be acquired absolutely. ‘The availability of very small design and their ability to acquire absolute angle positions at especially low cost is another great advantage single-turn encoders from SIKO.
