Triple Beam Adjustable Range Reflective Photoelectric Sensor MQ-W
Sensing objects can be detected at a constant distance using the triple beam sensing method
Hardly affected by color
Adjustable range reflective type sensor can detect white or black object at the same distance. Therefore, the sensor can even detect individual objects that are mixed with black objects or objects of various colors that were hard for the diffuse reflective type sensor to detect.
(However, when the background is specular, it may be necessary to change the angle of the sensor.)
Hardly affected by background
Adjustable range reflective type sensor dose not detect objects beyond the set range.
For this reason, malfunction does not occur even if there are moving machines or people passing by in the background.
Insusceptible to contamination on lens
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.
Visible light type and low hysteresis type are available
・Visible light type
Beam axis alignment can be performed by looking at the spot light.
・Low hysteresis type
Hysteresis between the ON and OFF status has been reduced by half (compared to conventional model).
Detection precision has been further improved!
Compact and slim size
A small size of W32 x H32 x D12.6 mm W1.260 x H1.260 x D0.496 in has been achieved for the 40 mm 1.575 in / 200 mm7.874 in sensing range type due to the built-in amplifier. In addition, you can mount the sensor both vertically and horizontally by diagonal mounting.
