Rotational speed sensor HAD, IAD/AHM series

Hall effect

Pulse sensors of the type magnetic field are suitable for the generation of rotation speed proportional pulse numbers and are equipped with either a Hall- or a magneto-resistant sensor element. For the pulse generation either a gear wheel or a rack rail made of steel,e.g. St37 are used, for whose width B applies: 4 mm < B < 0 sensor. With the mounting the right mounting position has to be considered. The axis of the pulse sensor has to be in line with the center of the gear wheel / of the rack rail. A lateral position marking allows an alignment parallel to the tooth flank and/or vertical to the actuating direction. The lateral displacement of the gear wheel / of the rack rail may not exceed 0.2 mm at the smallest width. The run-out should be < 0.2 mm. The fixing has to avoid reliably a vibration of the pulse sensor against the gear wheel / the rack rail.
