For the generation of adequate magnetic field levels, the fol-
lowing recommendations should be followed in the design and
specification of targets:
• 2 mm < tooth width, t < 4 mm
• Valley width, t
• Valley depth, h
• Tooth thickness, F ≥ 3 mm
• Target material must be low carbon steel

Although these parameters apply to targets of traditional
geometry (radially oriented teeth with radial sensing, shown in
figure 1), they also can be applied in applications using stamped
targets (an aperture or rim gap punched out of the target mate-
rial) and axial sensing. For stamped geometries with axial sens-
ing, the valley depth, h
tooth width, t, valley width, t
material specification need only be considered for reference. For
example, F can now be < 3 mm.
