Temperature sensor with a temperature-dependent actuating device (12) comprising a capillary tube (14) which is filled with a gaseous or liquid medium which—in case of temperature changes along a measuring distance formed by the capillary tube (14)—effects a pressure or volume change and which comprises a path transmission element (16) which is provided medium-tight at one end of the capillary tube (14) and exerts a stroke movement depending on the pressure or volume in the capillary tube (14), and with a sensor which is designed as a Hall-effect probe (27) and which detects, contact-free, the stroke movement of the path transmission element (16) via a magnet (34) arranged on the path transmission element (16) or a section pointing toward the Hall-effect probe (27) on the path transmission element (16) of a magnetic material, characterized in that the path transmission element (16) is fixed on the housing bottom (25), and that a printed circuit board (28) taking up the Hall-effect probe (27) is arranged—separate from the path transmission element (16)—on a housing section (41, 38) adjacent to or opposite the housing bottom (25) of the housing (24).
