Claim:
1. A speed sensor comprising: a sensing assembly including: a bobbin having a wire coil and a magnet for generating a magnetic field and a plurality of conductive pins in electrical connection with the wire coil; and a lead frame affixed to the bobbin, the lead frame providing an electrical connection between the conductive pins and a plurality of first conductive terminals; a first housing over-molded to the sensing assembly, the first housing having an upper flange proximate to an open top end, wherein the first conductive terminals protrude from the open top end; a second housing having a lower flange proximate to an open lower end, the lower flange joined to the upper flange of the first housing to form a plurality of weld windows, wherein the second housing contains a plurality of second conductive terminals proximate to both the open lower end and the first conductive terminals such that the weld windows provide an opening to allow the first conductive terminals to be welded to the second conductive terminals; and a flange overmold having a first opening operable to join the flange overmold to both the upper flange and the lower flange to seal the first housing to the second housing and fill the weld windows.
