Abstract

Si tratta di un attuatore, dotato di un tubo cilindrico (2), in cui è spostabilmente disposto un pistone (5) dotato di un magnete permanente (11). All'esterno del tubo cilindrico (2) per mezzo di un dispositivo di fissaggio (21) è disposto un sensore (18), azionabile senza contatto nel campo magnetico del magnete permanente (11), con distanza rispetto al perimetro esterno (17)del tubo cilindrico (2). Nella zona tra il sensore (18) e il tubo cilindrico (2) si trova un dispositivo di conduzione (23, 27) del campo magnetico per migliorare la trasmissione del segnale magnetico.It is an actuator, equipped with a cylindrical tube (2), in which a piston (5) equipped with a permanent magnet (11) is displacely disposed. Outside the cylindrical tube (2) by means of a fixing device (21) there is a sensor (18), which can be operated without contact in the magnetic field of the permanent magnet (11), with distance from the external perimeter (17) of the cylindrical tube (2). In the area between the sensor (18) and the cylindrical tube (2) there is a conduction device (23, 27) of the magnetic field to improve the transmission of the magnetic signal.
