Abstract

Die Erfindung betrifft einen induktivem Magnetsensor mit einem Joch, einer Spule, einem Permanentmagneten, der eine erste und eine zweite Polfläche aufweist, und einer Stirnfläche, wobei das Joch mit der Spule, mit der ersten Polfläche des Permanentmagneten und mit der Stirnfläche in magnetischem Kontakt steht. Der Magnetsensor umfasst ferner einen Streukörper, die mit der zweiten Polfläche des Permanentmagneten in magnetischem Kontakt steht. Die Erfindung betrifft ferner die Verwendung eines Streukörpers in einem induktiven Magnetsensor, wobei das Magnetfeld eines Permanentmagneten im wesentlichen durch den Streukörper hindurch geführt wird.
