2 W2S-2 | SICK
SEE NOT ONLY BLACK OBJECTS,
BUT ALSO THOSE THAT ARE
NEARLY INVISIBLE
The miniature photoelectric sensors in the new W2S-2 product family, can see even the blackest of black.
The blackest of black was discovered in 2002 in the form of the Ulysses Buttery, which is so black that
its light remission is less than 1%. Despite high light absorption, the Buttery would not y past the photo-
electric proximity sensors of the new W2S-2 product family unnoticed.
In practice, the high optical durability of the W2S-2 product family is of immeasurable value. This is not
only due to its ability to identify deep black and reective objects. The W2S-2 is the rst subminiature sen-
sor with autocollimation which is able to detect even transparent objects.
The ability to reliably detect objects of all types and characteristics is opening up entirely new possibilities
for machine development.
Combined with minimum space requirements and very wide sensing and scanning ranges, things could not
be clearer: W2S-2 is the miniature answer to maximum requirements.
The sensing range can be set with
millimeter precision via the control and
IO-Link. The inclusion of Smart Sensor
Solutions, such as counter functions,
false tripping suppression, and a time-
stamp, eases the load on the control
software.
it emits approximately 2.5 times more
light than the rst-generation PinPoint
LED. As a result, capabilities go beyond
detecting ultra-black objects. They gua-
rantee the rugged and reliable detection
of objects of all types.
This is just one highlight of the overall
innovation package which offers
numerous benets when it comes to
object detection.
To detect the deepest of blacks, the pri
-
mary requirement is a signicant amount
of light. Therefore, we have equipped
the W2S-2 product family with the latest
generation PinPoint 2.0 LEDs.
