Abstract

Eine Sensorspule, insbesondere für einen berührungslos arbeitenden, induktiven Wegmesssensor, mit zwei inneren, im Wesentlichen gleichartig ausgebildeten Wicklungsabschnitten (1), wobei zwischen den zwei inneren Wicklungsabschnitten (1) ein nicht bewickelter Abschnitt (2) vorgesehen ist, ist mit einfachen und wirtschaftlich darstellbaren Fertigungsmethoden herstellbar und weist dennoch die positiven Eigenschaften gattungsbildender Sensorsputen auf und ist dadurch gekennzeichnet, dass zwei äussere, im Wesentlichen gleichartig ausgebildete Wicklungsabschnitte (3) vorgesehen sind, die jeweils auf der dem nicht bewickelten Abschnitt (2) abgewandten Seite der zwei inneren Wicklungsabschnitte (1) angeordnet sind und dass die zwei äussere Wicklungsabschnitte (3) eine grössere Wicklungszahl als die zwei inneren Wicklungsabschnitte (1) aufweisen.
