To use the light of a Photoelectric Sensor through the hole, how large the hole should be?
Please make the hole of the same size as the lens diameter basically.
Please refer to the following so that the idea is different depending on the sensing method.
1. Idea to use the light through the hole
Please make the hole of the same size as the lens diameter to secure corridors of light regardless of the through-beam or the reflective.
When holes are smaller than the lens diameters, the rated sensing distance might not be satisfied because the amount of light decreases.
2. Notes by the sensing methods are as follows
