| • The area changes depending on the distance between the sensor and a work. Give such machinery configuration that it can keep constant distance if a precise area setting is necessary for the detection of a work. • Refer to the standard object distance of each model as to the distance between this sensor and a work. BS^See "Specifications" on Page 45. If the object distance is too near, the sensor becomes out of focus, causing a irregular lighting, while it is too far, the sensor is likely to receive the influence of the turbulence light since the light does not reach the work. • When a work moving very fast is going to be detected, the shutter time (brightness) has to be shortened. In such a case, make the distance between the sensor and a work closer or add additional external lighting since quantity of light becomes insufficient with only the built-in light in this sensor. US' See "Options" in Page 9. • The shutters of the image sensor of this device open in sequence from the right to the left in the screen. For this reason, the work moving from the right to the left is displayed wider and the one moving opposite is displayed narrower. • Please note that there may be dead pixels (pixels that cannot receive light correctly) with this image sensor. Although dead pixels may not detect or detect incorrectly, they will not be any problem on the practical use since they are very few. |
