Due to convergent distance sensing, the color or material of the object has almost no effect. Further, the background also has very little effect, enabling stable sensing. |

EX-43: Correlation between material and sensing range
|
It can be installed in a limited space.
|
Diffused beam type Even in a limited sensing area, the sensor is not affected by small perforations or unevenness. It is suitable for presence detection. |
 |
|
Spot-beam type – Visible red spot beam allows easy targetting. |
