(Excluding EQ-34W) sensing type sensor incorporating the 2-segment photodiode operates by sensing the variation in the incident beam angle. Thus, the output is activated according to the distance of the object from the sensor. Sensing is based on the difference in the This system helps the EQ-30 series in incident beam angle of the dotted line and the being unaffected by object color or a solid line in the above figure. background, enabling stable sensing. 241
