Abstract

A path sensor includes: a sensing device; at least two sensor units assigned to the sensing device, wherein the sensing device can be displaced relative to the sensor units and has a property changing at least once from a starting value to an end value along the sensing device, which property can be detected by the sensor units; and an evaluation unit, which is designed to determine the position of the sensing device relative to the sensor units as a function of the property values detected by the sensor units. The sensing device has at least two sections following on from one another in the direction of movement, along which sections the property changes from at least the starting value to at least the end value, wherein the change has different gradients in the sections.
