Chapter 2 – Introduction
The detection range depends on the mounting height of the sensor and the type of
the magnetic tape. As shown in Figure 1 above the sensor detects the deviation X
from the center of the track by measuring the horizontal magnetic flux density. The
higher the deviation the higher the output level.
Figure 3 shows the signals output vi the CAN/CANopen® interface when moving the
sensor in X direction above the magnetic tape (crosswise to the direction of travel).
