Abstract

Es wird eine Positionserfassungsvorrichtung zur Erfassung mehrerer Relativpositionen zwischen zwei relativ zueinander bewegbaren Bauteilen (2, 3) vorgeschlagen. Sie umfaßt eine an dem einen der beiden Bauteile (2) festgelegte Sensoreinrichtung (8), die mindestens einen mit einer Auswerteeinrichtung (12) verbundenen Signalleiter und wenigstens zwei Sensoreinheiten (38) aufweist. Mehrere Sensoreinheiten (38) sind gleichzeitig wenigstens einem Signalleiter derart gemeinsam zugeordnet, daß zur Übertragung der bei Betätigung dieser Sensoreinheiten (38) entstehenden Sensorsignale zur Auswerteeinrichtung (12) jeweils die gleichen Signalleiter genutzt werden. Jede Sensoreinheit (38) ist mit einer Codiereinrichtung ausgestattet, die ein charakteristisches Codiersignal hervorrufen kann, anhand dessen die Auswerteeinrichtung (12) die betreffende Sensoreinheit (38) erkennt.

A position detection device for detecting a plurality of relative positions between two components (2, 3) that can be moved relative to one another is proposed. It comprises a sensor device (8) fixed to one of the two components (2), which has at least one signal conductor connected to an evaluation device (12) and at least two sensor units (38). A plurality of sensor units (38) are simultaneously assigned to at least one signal conductor in such a way that the same signal conductors are used to transmit the sensor signals generated when these sensor units (38) are actuated to the evaluation device (12). Each sensor unit (38) is equipped with a coding device, which can produce a characteristic coding signal, on the basis of which the evaluation device (12) recognizes the relevant sensor unit (38).
