Abstract
A position measuring apparatus includes (a) a sleeve that has an open first end and a second end opposite the first end, (b) a guide pin guided at least partly in the sleeve, (c) a spring, (d) a linear magnetic field sensor and (e) a magnet disposed adjacent to the linear magnetic field sensor. To avoid wear even in the presence of large temperature fluctuations, the magnet is disposed on a face of the guide pin facing the second end of the sleeve, and the spring is disposed between the second end of the sleeve and the magnet such that the spring urges the magnet against the guide pin.
