SICK deTec4 Ex - Integration in Electrical Control; Direction of Transmission

Using reversed direction of transmission
T
he direction of transmission of the system 2 can be changed during installation by
switching the positions of the sender and receiver. With reversed direction of transmis‐
sion, the receiver 2 is not affected by the infrared light from the sender 1.

4.3.4.3 Combining beam coding and reversed direction of transmission
To prevent a mutual interference in the case of more than two neighboring systems,
be
am coding and reversed direction of transmission can be combined.

Figure 16: Trouble-free operation of 4 neighboring systems due to beam coding and reversed
dir
ection of transmission
In the figure, the beam coding of the systems arranged next to each other is different.
The direction of transmission of the systems arranged on top of each other is reversed.
This prevents the systems from interfering with each other.
