  • Patent number: 11733063
    Abstract: A position sensor includes a detector and a signal processor. The detector includes: a sensor chip having a surface; a first detection element disposed at the surface of the sensor chip; and a second detection element disposed at the surface of the sensor chip. The signal processor processes a signal input from the detector. The first detection element outputs a first detection signal corresponding to a position of a detection target, based on a change in a magnetic field received from the detection target. The second detection element outputs a second detection signal corresponding to the position of the detection target, based on the change in the magnetic field received from the detection target. A center of balance of the first detection element coincides with a center of balance of the second detection element.

  • Patent number: 11099034
    Abstract: A position sensor includes a detector and a signal processor. The detector includes a magnet generating a bias magnetic field and a detection element configured to be applied by the bias magnetic field, and generates plural detection signals including distinct phase difference and corresponding to plural ranges aligned in one direction along a movement direction of a detection target, based on a change in a magnetic field received by the detection element from the detection target with a movement of the detection target having a magnetic body. The signal processor acquires the detection signals from the detector, compares the detection signals with a threshold value, and specifies a position of the detection target as a position at one of the ranges based on a combination of magnitude relation between the detection signals and the threshold value.

  • Publication number: 20200072593
    Abstract: A position sensor includes a detector (122) and a signal processor (123). The detector generates detection signals, which have a distinct phase difference and which respectively correspond to ranges aligned in one direction along a movement direction of a detection target (200, 202, 203) having a magnetic material, based on a change in a magnetic field received from the detection target along with a movement of the detection target. The signal processor acquires the detection signals from the detector, compares the detection signals with a threshold value, and specifies a position of the detection target as a position covered by one of the ranges based on a combination of magnitude relations of the detection signals and the threshold value.
