FIELD: physics.
SUBSTANCE: contactless angular position sensor has a dipole annular magnet with diametric magnetisation, whose axis is superimposed with the axis of rotation of the object, and a Hall sensor which is shifted from the axis of rotation of the annular magnet, wherein the angle between the plane of sensitivity of the Hall sensor and the plane which passes through the end surface of the annular magnet is equal to 40°±10°, and the distance from the centre of the Hall sensor to the axis of rotation and to the plane which passes through the end surface of the annular magnet is equal to 0.9±0.3 and 1±0.25 times the outer radius of the annular magnet, respectively.
EFFECT: high linearity and adjustment of sensitivity of the sensor with increase in sensitivity.
