2 The PosCon-system
The sensor consists of infrared emitters, a receiver, the electronic components and the interface. In
addition, a reflective tape is necessary.
For orientation, the system has a right “R” and a left “L” side and is indicated on the sensor housing.
This corresponds to the analog output of the signal, “L” side equals 4mA while “R” side equals 20mA
Every change from bright to dark or dark to bright inside the measuring range is an edge for the sen-
sor. Corresponding to the chosen measuring mode the sensor evaluates these edges and displays it
on the analogue output.
