These magnetic encoder systems meet IO-Link’s smart sensor profile 2.0 specifications, adding four switching signal channels to the process data. Each channel uses IO-Link to program an on and off point for the encoder, which allows measurements to be limited to set ranges or windows. An enhanced version of the encoder also adds condition monitoring functions to report signal quality and a low signal threshold to alert when maintenance may be needed. Developed for measuring and positioning applications, these encoders provide absolute measurement by traveling above a magnetically coded strip that can be up to 8 m long, with a read distance of 1.3 mm.
