SENSOR FOR MEASURING THE MAGNETICALLY RESPONSIVE CHARACTERISTICS OF TOKENS
An improved magnetic field sensor has one Hall-effect sensor (226) located between a magnet (227) and the inclined token track base (56) and another Hall-effect sensor (228) located between another magnet (229) and the inclined token track base. The Hall-effect sensors are placed at distances above...

Abstract | An improved magnetic field sensor has one Hall-effect sensor (226) located between a magnet (227) and the inclined token track base (56) and another Hall-effect sensor (228) located between another magnet (229) and the inclined token track base. The Hall-effect sensors are placed at distances above the inclined token track base which optimize their accuracy in detecting tokens (37, 39) which have two concentric regions with different magnetic characteristics.
Un capteur de champ magnétique amélioré comporte un capteur à effet de Hall (226) situé entre un aimant (227) et la base de la voie de jetons inclinée (56), ainsi qu'un autre capteur à effet de Hall (228) situé entre un autre aimant (229) et la base de la voie de jetons inclinée. Les capteurs à effet de Hall sont placés à certaines distances au-dessus de la base de la voie de jetons inclinée, lesquelles optimisent leur précision de détection de jetons (37, 39) présentant deux régions concentriques de caractéristiques magnétiques différentes. |
