Magnetic Incremental Encoders
A magnetic incremental encoder is a magnetic scale or magnetic ring with regular intervals with magnetic north and south poles. The reading head samples sinusoidal magnetic fields above the magnetic measuring scale in such a way that the process is contact-free and avoids wear and tear. The distance of the MR sensor head to the surface of the magnetic scale can be up to 2 mm in the case of a scale with a 5 mm magnetic spacing. The sine-cosine signals generated in the sensor head, which are displaced by 90°, are output without any time delay as RS422-compatible impulse signals via the integrated interpolation electronics working in conjunction with the reference signal. Resolutions of up to 5 µm are available as standard.
