Very accurate detection by triple beam triangulation sensing method in a compact package.

FEATURES

Accurate detection regardless of
color, material, or shape of objects
Area reflective type sensor can detect
white or black object at the same dis-
tance. In case of diffuse reflective type,
it is difficult to detect objects of various
color with the same sensitivity setting.
MQ-W area reflective type sensor is
useful for such a case.

No-miss operation regardless of
back-grounds
Area reflective type sensor does not
detect objects beyond the set range.
Resistant to lens surface soiling
Area reflective type sensor detects the
distance by the angle, not the intensity
of received light. Even if the lens sur-
face is soiled by dust or any powdery
material, there is a little variation of
sensing range.

Environmental resistance
Immersion protected construction
(equivalent to IEC IP67)
High speed detection: Max. 2 ms
Light-ON/Dark-ON output is wire
selectable.
Operating voltage of 12 to 24 V DC
