MEYLE Absolute Encoder

Absolute encoders have a disk with a digital coding on concentric tracks. This code is read by a Opto-Asic. A unique bit pattern is assigned to each position. The advantage is, that after power failure true position verification is available as soon as power is up again, even if the shaft was moved during the dead state.
 

No reference drives after starting-up are necessary as with incremental systems. Safety is increased and the time taken for reference drives is saved.
