That is better than I would have expected but in reality no where near enough for a machine tool such as a mill or a lathe even if you do manage to get it as good as 0.02mm. I think I remember you saying it was a granite cutter you have, that kind of accuracy is more than likely much better than you need :)

probably an optical switch would be the most accurate but it would depend on the environment whether it would be the best. If there is a lot of dirt and dust then and optical would need to be enclosed and the flag operated by a plunger which exits from the side of the encosure so that dust isnt a problem.
 You may be better with a prox switch if it is no magnetic material you will be cutting, they can be accurate as well.
