Abstract

La présente invention concerne un capteur (10) de position linéaire à deux axes, qui comprend un boîtier extérieur (12), un actionneur (40), un détecteur linéaire à effet Hall (20) pour détecter les changements de position le long d'un premier axe (y) et un détecteur linéaire à effet Hall (30), pour détecter les changements de position le long d'un deuxième axe (x). Le boîtier (12) est de préférence fait d'une matière non magnétique, par exemple de la matière plastique. L'actionneur (40) est en forme de tige et accouplé à un dispositif mobile ou à un arbre (non représenté) dont on veut détecter la position. Le détecteur linéaire à effet Hall (20) est positionné, sans fixation, pour se placer sur la lèvre (52) du boîtier (12) et il comporte une pièce polaire (26) conductrice magnétiquement, un montage d'aimants (24) comprenant un aimant supérieur (21) et un aimant inférieur (23) qui sont séparés par un entrefer (25). Le montage d'aimants (24) et la pièce polaire (26) sont placés autour d'un support (14) de capteur à effet Hall, dans une configuration ou forme en U. Ce support (14) est monté de manière fixe sur le boîtier (12) par la zone de fixation (54). Le capteur linéaire à effet Hall (20) comprend aussi un élément capteur fixe à effet Hall (22), fixé au support (14) de capteur à effet Hall, sur la surface (15). Le capteur linéaire à effet Hall (30) est positionné approximativement à 90°, dans un sens et dans l'autre, du capteur linéaire à effet Hall (20).
