ABSTRACT:
A magnetic sensor is provided which utilizes a molded magnet with a channel formed therein. A magnetically sensitive component, such as a Hall effect element, is attached to a substrate or printed circuit board. The printed circuit board, or substrate, is provided with an opening through its thickness that is shaped to accept a post with a certain amount of clearance therebetween. This allows the printed circuit board to be moved relative to the magnet during calibration procedures and then rigidly attached in a position relative to the magnet by soldering the post to the substrate or printed circuit board. This places the magnetically sensitive component at a desirable location relative to the magnet and within the channel formed in the magnet. The post can be molded into the magnet or formed as an integral portion of the magnet.
