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.
