2) Old conductor coloring in brackets.
3) There must be no ferromagnetic material in the vicinity of the read head or the actuator.
All data refer to the frontal approach direction and a center offset of m = 0.
4) The minimum switching distance S
omin
between read head and actuator is 1 mm. If the distance is
less than this, the evaluation unit changes to the fault state.
