1) Old conductor coloring in brackets.
2) 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.
3) The LED for the contact status indication has an internal series resistor of 1.5 k
Ω.
4) Operating distance for contact status indication and LED.
