Title (EN) PRECISION NON-CONTACT DIGITAL SWITCH
(FR) COMMUTATEUR NUMERIQUE DE PRECISION SANS CONTACT
Abstract: front page image
(EN)A switch apparatus, system and method are disclosed herein, including one or more magnetic sensing elements that follow a travel path thereof, and a plurality of permanent magnets located in a mirrored configuration about the travel path. Such a configuration permits a magnetic field variation associated with the permanent magnets and the magnetic sensing element to be reduced with respect to the magnetic sensing element and the permanent magnets position tolerances, thereby generating a reduced magnetic field variation thereof which improves switching accuracy. A signal processing module can also be provided, which includes a signal conditioning circuit associated with a microprocessor.
(FR)L'invention concerne un dispositif, un système et un procédé de commutation reposant sur l'emploi d'un ou de plusieurs éléments de détection magnétiques suivant un chemin de déplacement le long duquel se trouvent plusieurs aimants permanents disposés en miroir. Cet agencement en miroir permet une réduction de la variation du champ magnétique associé aux aimants permanents et au éléments de détection magnétiques par rapport aux tolérances de position des uns et des autres, ce qui a pour effet d'améliorer la précision de commutation. Le dispositif peut également être équipé d'un module de traitement du signal assorti d'un circuit de conditionnement du signal associé au microprocesseur.
