Magnetic encoders like would be used for making copies of magnetic swipe Credit/Debit Cards?
There are many types of magnetic encoders so that is just the first type that comes to mind.
Sony once made one called a Magnascale. It would allow linear measurement to less than .001". Is that the kind of magnetic encoder you are looking for? Or are you looking for a magnetic reed switch. Quite a range of variety. Can you be more specific on what you want to do with the sensor?
Take a look at the links of this page on magneto resistive sensors:
