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.
