<p>A low cost Hall position sensor comprises a standard surface mount Hall effect sensing device (2) having its three leads (4, 6, 8) soldered directly to an exposed electro-conductive end portion of a standard flexible multiconductor circuit (42). The flexible circuit (42) may be custom designed and manufactured at low cost for a variety of mass production applications. The position sensor further comprises a permanent movable Hall magnet (82) disposed proximate to the soldered Hall effect sensing device which remains stationary during operation. The Hall effect sensing device (2) picks up variations in the magnetic flux generated by the movement of the Hall magnet during operation and sends a corresponding feedback voltage signal to an external controller which powers the Hall effect sensing device via the flexible circuit (42). The flexible circuit (42) has a second exposed electro-conductive end portion (46) for removably mating with a corresponding flex circuit connector on the controller board. The Hall position sensor may be used in applications involving a moving Hall effect sensing device (406) disposed proximate to a series of stationary Hall magnets (404a-404k).</p> |
