4.3. Tooth profile
Any tooth profile is admissible. The top width of the tooth should be 2.5 mm minimum,
the gap and the depth of the gap at least 4 mm. For index plates the same dimensions are
valid.
Due to tolerances, a radial arrangement of the magnetic pick-up is preferable..
4.4. Clearance of Magnetic Pick-up
The distance between the magnetic pulse pick-up and the tooth top should range from 0.5
and 0.8 mm. (It is possible to screw in the magnetic pick-up till it touches the tooth and
then unscrew it for about half a turn.)
