nfrared photoelectric switches can be used in various applications. When using infrared photoelectric switches, attention should be paid to environmental conditions so that the infrared photoelectric switches can work normally and reliably. Infrared photoelectric switches generally work stably when the ambient illuminance is high. However, it should be avoided that the optical axis of the sensor faces strong light sources such as sunlight and incandescent lamps. Commonly used infrared photoelectric switch classification method: According to the detection method, it can be divided into three types: reflection type, opposite beam type and specular reflection type. The through-beam detection distance is long and can detect the density (transmittance) of translucent objects. The reflective working distance is limited near the intersection of the beams to avoid background effects.
