POSITION SENSOR AND LINEAR ACTUATOR
First Claim
1. A linear magnetic position sensor, comprising:
- a magnetic field generating unit having two permanent magnets for generating a magnetic field,a Hall sensor disposed in a region of the magnetic field forming a linear measuring section, wherein the Hall sensor and the magnetic field generating unit are linearly displaceable relative to one another along a longitudinal direction in order to position the Hall sensor within the measuring section,wherein the permanent magnets are polarized in a transverse direction running perpendicular to the longitudinal direction,wherein the permanent magnets are spaced apart from one another in the longitudinal direction,and wherein each pole of one of the permanent magnets is connected to a pole of the other permanent magnet via a magnetic conductor element.

Abstract
A linear magnetic position sensor may include a magnetic field generating unit having two permanent magnets for generating a magnetic field. A Hall sensor may be disposed in a region of the magnetic field forming a linear measuring section, wherein the Hall sensor and the magnetic field generating unit are linearly displaceable relative to one another along a longitudinal direction in order to position the Hall sensor within the measuring section. The permanent magnets may be polarized in a transverse direction running perpendicular to the longitudinal direction. The permanent magnets may be spaced apart from one another in the longitudinal direction. Each pole of one of the permanent magnets may be connected to a pole of the other permanent magnet via a magnetic conductor element.
