Correlation between sensing object size and sensing range
|
|
As the sensing object size becomes smaller than the standard size (white non-glossy paper 200 × 200 mm 7.874 × 7.874 in), the sensing range shortens, as shown in the left graph. |

• Vertical (up and down) direction |

|
Correlation between lightness and sensing range
|
|
The sensing region (typical) is represented by oblique lines in the left figure. However, the sensitivity should be set with enough margin because of slight variation in products.
(Lightness shown on the left may differ slightly from the actual object condition.) |
Correlation between material (50 × 50 mm 1.969 × 1.969 in) and sensing range
|
|
The bars in the graph indicate the sensing range (typical) for the respective material.
However, there is a slight variation in the sensing range depending on the product.
Further, if there is a reflective object (conveyor, etc.) in the background of the sensing object, since it affects the sensing, separate it by more than twice the sensing range shown in the left graph. |

Correlation between lightness and sensing range
|
|
The sensing region (typical) is represented by oblique lines in the left figure. However, the sensitivity should be set with enough margin because of slight variation in products.
(The graph is drawn for the maximum sensitivity setting.)

However, there is a slight variation in the sensing range depending on the productFurther, if there is a reflective object (conveyor, etc.) in the background of the sensing object, since it affects the sensing, separate it by more than twice the sensing range shown in the left graph, or adjust the sensitivity adjuster.

Correlation between sensing object size and sensing range
|
|
As the sensing object size becomes smaller than the standard size (white non-glossy paper 100 × 100 mm 3.937 × 3.937 in), the sensing range shortens, as shown in the left graph. |
