Comparision between MQ-W20A and former product
Condition: Target (40i 60 mm 1.575i 2.362 inch ),
target assumed as natural shape
For the former product (diffuse reflective type),
depending upon the object material, the operating range varied greatly, but for the triple beam type there a little variation.100.01520.06630.09840

Fig. 1 Optical triangulation range measurement method Other examples of this method are
the automatic focusing and camera
range measurement systems.
Fig. 2 Triple beam range measure-ment method By averaging the range measure-ment signals of the 2 light receiving systems, the range measurement
difference is cancelled.
Fig. 4 PSD (position sensitive device) construction By making a calculation of the ratio of I 1and I 2, the light spot position Fig. 3 Light beam trace of the lens (a) is a spherical lens, and (b) is the aspherical lens. Because there is no aberration in (b), range measure-ment precision is high.Fig. 5 Signal processing circuit block diagram
5) Avoid using in a location with high concentrations of steam, dust, or corro-sive gas.
6) The sensor is of immersion protected type, but this does not mean that it can be used in water or where there is direct impingement of rain for detecting objects.
