Abstract: A calibrated, low-profile magnetic sensor and method for forming such a sensor are described herein. Generally, a magnetic sensing device is formed within a housing, wherein the magnetic sensing device comprises at least one magnet. The magnetic sensor includes a compact integrated circuit package such as, for example, a small outline integrated circuit package (SOIC). A magnetic sensing element is generally mounted to the compact integrated circuit package. The magnetic sensing device can be configured to additionally incorporate a printed circuit board (PCB) having a hole formed therein such that the compact integrated circuit package can be surface mounted off-center on the printed circuit board, so that the hole can be located within the printed circuit board to match a shape of the magnet, allowing the magnet to pass through the circuit board adjacent to the SOIC to complete the magnetic circuit.
