Limit switch function

When limit switch functionality is
needed, sensing heads can be
equipped in addition with a limit
switch sensor which senses
opposite pole permanent magnets
at the ends of the measuring range
and sends the signals to the
controller (Fig. 3-5).
The limit switch sensors function
then even if the rest of the sensor
fails (security function).
If the actuation range of the limit
switches needs to be longer than
their length (20 mm), multiple limit
switches of the same type can be
mounted in rows.
