Abstract

A device for registering the displacement travel and/or the displaced position of a sliding component, which is moved free of torsion, of a linear drive is intended to be implemented on a small scale and with display precision. For this purpose, the device is equipped with at least two magneto-resistive sensors which act within a separate magnetic field, respectively assigned to the displacement component in different regions located one behind the other.
