Description
Annäherungsschalter Der Erfindung liegt die Aufgabe zugrunde, einen an sich bekannten Annäherungsschalter, bei dem ein Magnetfeld und ein Hallspannungsgenerator sich relativ zueinander bewegen, so auszubilden, daß das relativ zum Hallspannungserzeuger sich bewegende Magnetfeld auch durch ein Weicheisenteil ersetzt werden kann.Proximity switch The invention is based on the object of providing a Proximity switch known per se, in which a magnetic field and a Hall voltage generator move relative to each other, so train that the relative to the Hall voltage generator moving magnetic field can also be replaced by a soft iron part.
Erreicht wird dieses gemäß der vorliegenden Erfindung dadurch, daß der Hallspannungsgenerator mit einer dauernd einwirkenden Vormagnetisierung versehen ist.This is achieved according to the present invention in that the Hall voltage generator is provided with a permanently acting premagnetization is.
Weiterhin ist es von Vorteil, daß sämtliche Bauteile des Schalters in an sich bekannter Weise in einem gemeinsamen Schaltgehäuse gelagert sind.It is also advantageous that all components of the switch are stored in a known manner in a common switch housing.
Durch die Vormagnetisierung wird es möglich, den an sich bekannten Annäherungsschalter mit Hallgenerator auch durch vorbeigeführte Weicheisenteile zu beeinflussen. Bei diesem Schalter kann somit auf an den Fahrzeugen, beispielsweise Förderwagen angeordnete zusätzliche Betätigungsmagnete verzichtet werden, da allein der Einfluß des Eisens durch Störung der Vormagnetisierung eine unterschiedliche Hallspannung hervorruft und dadurch die entsprechende Schaltung veranlaßt wird.The premagnetization makes it possible to use the one known per se Proximity switch with Hall generator, also by passing soft iron parts to influence. This switch can thus be on the vehicles, for example Trolley arranged additional actuating magnets are dispensed with, as alone the influence of iron by disturbing the premagnetization is different Hall voltage causes and thereby the corresponding circuit is initiated.
