Furthermore, the devices also
incorporate a large number of
features that are usually only
found in special versions, e.g. the
test input of the WS/WE 18-2
and WL 18-2, the adjustable
scanning distance with back-
ground suppression of the
WTV 18-2, individual plugs, or
status LEDs as signal strength
indicators, alignment aids, or pre-
failure signalling output.

systems as well as for packaging internally adjustable optics, state-

background suppression and op-

ranges are an additional feature: film on a stainless steel chain
up to 20 metres for the through- conveyor, or drinking straws

7 metres for the photoelectric
reflex switch and 600 mm or

proximity switch (depending on
whether a red light or infrared
light source is used).
– all of these tasks can be
mastered without any problem
with the WTV 18-2.
