Whereas optical or capacitive sensors can be unreliable in harsh conditions, IncOders are generally unaffected by foreign matter and IP68 rated versions are available. Unlike capacitive devices, there is no need to earth the Rotor or Stator. Robust, hard-anodized aluminum alloy housings and monolithic constructions are used throughout.
The Stator contains all the electronics to receive power and output a signal, showing the angle of the Rotor relative to the Stator. IncOders are truly absolute which means that they need no motion at power up to determine position. Compliant or special couplings are not required, so the Rotor & Stator can simply be fixed directly to the host product. Precise mechanical mounting is not necessary to achieve high measurement performance and there are no bearings. The measurement performance stated in this Product Guide is guaranteed provided that the IncOder is installed as per its installation tolerances.
