MQ-W20C-DC12-24V (PANASONIC)

The MQ-W series Reflective Photoelectric Sensor with amplifier built-in. Sensing objects can be detected at a constant distance using the triple beam sensing method. Adjustable range reflective type sensor can detect white or black object at the same distance. Adjustable range reflective type sensor dose not detect objects beyond the set range. Adjustable range reflective type sensor detects the distance by the angle, not by the light receiving intensity. Even if the lens surface is soiled by dust or any powdery material, there is little variation of sensing range. In addition, the sensor stably detects approaching objects at a fixed distance because the distance is sensed by the angle of received light.
