W4-3
Miniature photoelectric sensors series
The ef cient space savers
It is the little things that make them
“big”: minimum size, maximum
versatility. Three versions of the W4-3
series offer you the following bene ts
for your application:
Clearly visible light spot.
The integration of new Pin-Point LEDs
creates brilliant, tightly de ned light
spots. Thus, the photoelectric sensors
can be aligned easily and quickly, as
the light spot is easy to see even in
bright ambient conditions.
Photoelectric re ex sensor with
switching threshold adaptation and
autocollimation.
Transparent objects of all kinds can
be reliably detected in dif cult and
changing ambient conditions, with the
switching threshold being automati-
cally adapted to the changing ambi-
ent conditions, such as dust gather-
ing on the optical surfaces.
Best background suppression in its
class.
Background suppression offering
more than just a good black/white
displacement, i. e. object detection
in front of re ective and moving
backgrounds. The sensor has a 2nd
sender LED allowing the sensor to
see “spatially”.
Optimum ambient light suppression.
The photoelectric proximity sensor
needs to detect objects directly in
front of an energy-saving lamp or a
uorescent lamp – no problem.
Light from such sources is identi ed
and suppressed.
Hygienic and safe to use in aggres-
sive environments.
Hydro uoric acid, coolants, alcohols
etc. cannot affect the fully Te on-
encapsulated versions – even when
exposed for long periods.
