Magnetic detection device with a dual magnetic flux path

The device has a permanent magnet associated to a magnetic flux sensor (5) by a frame (6) for circulation of magnetic flux generated by the magnet towards the sensor. The frame has two arms (9, 10) defining respectively two magnetic flux circulation paths. One path has a variable reluctance which is...

More Information
Summary:The device has a permanent magnet associated to a magnetic flux sensor (5) by a frame (6) for circulation of magnetic flux generated by the magnet towards the sensor. The frame has two arms (9, 10) defining respectively two magnetic flux circulation paths. One path has a variable reluctance which is reduced when a magnetic unit is opposite to one arm. The path has a total interference lower than total interference of the other path. Dispositif de détection de présence d'élément magnétique, le dispositif de détection comportant au moins un aimant (4) permanent associé à un capteur (5) de flux magnétique par au moins une armature (6) de circulation vers le capteur d'un flux magnétique engendré par l'aimant, l'armature comprenant un premier bras un deuxième bras (9, 10) définissant respectivement un premier et un deuxième chemin de circulation du flux magnétique, au moins le premier chemin ayant une réluctance variable qui est réduite lorsque l'élément magnétique est en regard du premier bras.
