Product introduction
Photoelectric sensor is a device that converts optical signal into electrical signal.
Its working principle is based on photoelectric effect.
Photoelectric effect refers to the phenomenon that when light shines on some
substances, the electrons of substances absorb the energy of photons and produce
the corresponding electrical effect.
According to the different phenomena of photoelectric effect, the photoelectric
effect is divided into three types: external photoelectric effect, internal photoelectric
effect and related voltage effect.

Characteristics of slot Optocoupler
1. Compared with the proximity switch, the photoelectric switch has a very long
detection distance and is contactless, so it will not damage the detection object and
will not be affected by the detection object. It is hardly restricted by the detected object.
2. Because it adopts the way of reflection and light transmission on the surface of the
detection object, unlike the proximity switch, it can only detect metal, glass, plastic, wooden
objects, liquids and other substances. Fast response.
3. Like the proximity switch, it can detect objects moving at high speed because there is
no mechanical movement
4. Almost unaffected by general lighting.
