Abstract
A sensor for detecting the position of a fuel injection element such as a needle injector, poppet valve, or the like in fuel injection apparatus of an internal combustion engine includes a header of an electrically insulating material having opposing first and second surfaces. The sensor is provided with plural conductive leads, each coupled to the first surface of the header, and a Hall effect detector mounted on the second surface of the header for detecting a magnetic field and changes therein responsive to movement of the fuel injector element. Metallization between the first and second surfaces interconnects the leads to the detector, and the header, leads and detector are encapsulated and dimensioned for insertion into and removal out of the passageway in the fuel injection apparatus.
