Photoelectric switch reflectivity

The detection is a measurement of the reflectance of a glossy or smooth metal surface, which is generally very high, very like a mirror image. The projector and the detection should be installed at an angle of 10-20 degrees, so that the optical axis is not perpendicular to the detected object. Object, this helps prevent wrong operations.

This does not include background effects using reflective diffusion type investment, which is detected by light, sometimes due to the detection of objects from the background object, the photoelectric switch, the background is smooth and the object with high reflectivity, and possibly the photoelectric switch cannot be stable detection. You can use a limited casting distance, light receiver, or use a background far away from the object and the object to remove the background, the background is too dark, or try to make the background rough and dark.

Precautions for the use of photoelectric switches can be used in various applications. When using the photoelectric switch, pay attention to the environment so that the photoelectric switch can work normally and reliably. In order to avoid the strong Guangyuan photoelectric switch in high ambient lighting, it can generally work stably.
