Abstract

A linear sensor is described with a casing (5), with a pin (7) which contains a permanent magnet (1) and which is mounted in the casing (5) in a linearly displaceable manner against the force of a spring (6), and with a magnetic field sensor (3) attached to said casing (5) for detecting of a displacement of the permanent magnet (1). The invention provides that the pin (7) is controlled by a first cylindrical guide (8) and a second cylindrical guide (8).
