ABSTRACT:
A Hall-effect magnetic sensor arrangement comprises a sensor element utilizing the Hall-effect and disposed in a magnetic circuit including a magnetic pole unit in an opposing relationship with respect to the magnetic pole unit with a predetermined distance therebetween, a sensor frame surrounding the sensor element and having a cave defined at the opposite side of the magnetic pole unit with respect to the sensor element and at a side perpendicular to a magnetic path and a soft filler material filled in the cave for protecting the sensor element. The sensor arrangement comprises a nonmagnetic thin plate member disposed at the side of the sensor element opposite to the magnetic pole unit and supported at its outer edge by the sensor frame for preventing the filler material to flow out from the cave.
