Title: Magnetic sensor
Inventor: URANO MITSUHIRO
IPC: G01P3/488
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain a small, high sensitivity magnetic sensor. SOLUTION: The magnetic sensor 1 comprises a magnetoelectric conversion element, i.e., a Hall IC 2, and two magnets 3A, 3B arranged on the opposite sides thereof. The magnets 3A, 3B direct same pole toward the Hall IC 2 and they are set to cancel the field in the vicinity of the detecting point of the Hall IC 2. Consequently, the axial flux density of the magnetic sensor 1 is 0 in the vicinity of the intermediate point and maximized on the surface of both magnets while reversing the direction. When the interval between both magnets is shortened, the distance between the magnetic sensor and the magnet can be shortened as compared with a case employing one magnet and thereby the size of the sensor can be reduced.
