POSITION DETECTOR AND POSITIONING DEVICE |
摘要 |
A position detector (3) capable of obtaining an output having a linearity in a wide range includes: a magnetic field generating member (11) attached to a movable member (10) movable in a predetermined movable direction (x); and magnetic field detection means (12) for detecting a magnetic field change caused by movement of the magnetic field generating member (11). The magnetic field generating member (11) includes an N-pole portion (13) magnetized into N-pole, an S-pole portion (14) magnetized into S-pole arranged in the movable direction with the N-pole portion (13), and a non-magnetized portion (15) not magnetized between the N-pole portion (13) and the S-pole portion (14).
