An axial sensing configuration is where the conductive target moves along an axis that is perpendicular to the plane of the coil, as shown in the upper section of Figure 1-1. The LDC sensor measures the change of inductance caused by the movement of the target. The target is constrained so that it only moves in one axis. As the target distance from the sensor varies, the LDC output will correspond to the target distance.
This common configuration can be used for a wide variety of systems, from measuring extruded material to sensing whether a door is open or closed.
