A magnetic sensor assembly having a sensor (10) with an integrally-formed magnet (12) and housing (14). The magnet is preferably moulded from a molten mixture of plastic and magnet powder and positioned within the housing so that a portion of the magnet is exposed for direct contact with the ball (18). The strength of the magnet may be varied by simply adjusting the plastic powder-magnet powder ratio. Because the magnet and the ball are in direct contact when the ball is seated in the sensor, lower energy and less expensive magnetic materials may be used. Moreover, the colour of the housing may be changed to reflect different magnet strengths to facilitate placement of the proper sensor in a correct given vehicle.
