Abstract (de)

Die Erfindung beschreibt die Ausbildung eines Gebers für pneumatisch oder hydraulisch wirkende Arbeitszylinder mit Endlagenverriegelung, der nach der Verriegelung in der jeweiligen Endlage anspricht, innerhalb der Arbeitszylinders mit reproduzierbarem Schaltpunkt angeordnet, temperaturunabhängig, druckunabhängig, robust sowie einfach und kostengünstig zu realisieren ist. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß im Führungsverschlußteil (4) oder/und im Bodenverschlußteil (5) ein gegenüber dem Arbeitszylinder elektrisch isolierter Kontaktstift (17) angeordnet ist, der in Verbindung mit einem Verriegelungskolben (7) einer Modulareinheit (6) zur Endlagenverriegelung als Schließer ausgebildet ist. <IMAGE>
