ATTENTION!
Degree of protection IP 67 is achieved only if the connectors and caps are screwed into place!
NOTE
The switching input/switching output are programmed using the Sensor Studio configuration
software. For further information, see also Chapter 10.
ATTENTION!
If you use a sensor with a standard M12 connector, then please note the following:
Use only sensors on which the switching output does not lie on pin 2 or sensor cables on
which pin 2 is not assigned. Otherwise, the switching output is not protected against feedback
on the switching input. If the inverted sensor output lies on pin 2, erroneous behavior of the
switching output will result.
