ABSTRACT:
A variable reluctance sensor assembly including an open-ended housing which contains a bobbin assembly with an overmolded connector piece. The bobbin contains a ferrous pole piece pressed into a closed-ended cavity within the bobbin, a small disc-shaped rare earth permanent magnet mounted forward of the pole piece, and a magnet wire coil wound upon the bobbin barrel and attached to the customer terminals which carry the output signal. A separate submersible connector is affixed to the integral connector. A front seal ring is stretch fit to the forward flange of the bobbin, and a rear seal ring is stretch fit to the rear section of the sensor housing. The bobbin assembly is slip fit into the housing with magnet forward. Upon the bobbin assembly being initially seated with the magnet in the open magnet pocket of the housing, the connector piece is ultrasonically welded via shear joint to the housing, thereby simultaneously compressing both O-rings, fully seating the magnet into the open pocket in the housing, and fully seating the bobbin assembly into the housing. In an alternative embodiment, a leaded sensor assembly may be provided with a harness holder in place of the connector piece.
