Abstract:
1. A non-contact sensing module, comprising: a coil printed circuit board in which a reference pattern coil is formed at an upper surface thereof and in which a sensing pattern coil is formed at a lower surface thereof wherein a mounting hole is formed at a center of the coil printed circuit board; and a main printed circuit board that is coupled to the mounting hole and that is disposed at the upper surface of the coil printed circuit board and that is electrically connected to the reference pattern coil and the sensing pattern coil, wherein the reference pattern coil is wound in a predetermined number of times at the upper surface of the coil printed circuit board, wherein a start tab of the reference pattern coil is disposed at an edge side of the upper surface of the coil printed circuit board, wherein an end tab of the reference pattern coil is supported by both surfaces of the coil printed circuit board by passing through the mounting hole, wherein the sensing pattern coil is wound in a predetermined number of times at a lower surface of the coil printed circuit board, wherein a start tab of the sensing pattern coil is disposed at an edge side of the lower surface of the coil printed circuit board, and wherein an end tab of the sensing pattern coil is supported by both surfaces of the coil printed circuit board by passing through the mounting hole.
