1.4.2.2 Recommended Air Gap
The recommended air gap between the sensor front surface and the rotating part must be
observed. It increases with the size of the profile: For cams or milled grooves with their width,
distance and depth, for a gear with its module (= diameter / number of teeth). The field between
grooves or cams must be at least as large as the specified width (W), the depth D = at least 3
mm. Thickness of a gear or length (T) of a milled recess of at least 5 mm (plus a possible axial
displacement).
The guideline values given below for the profile size (D / W / T) of a rotor are the minimum
dimensions, they may be exceeded in any direction. However, the maximum permissible air gap
between the sensor and the pole wheel will not increase.
