Optocoupler transmits electrical signals through light. It has a good isolation effect on input and output electrical signals. At present, it has become one of the optoelectronic devices with the most kinds and the most widely used. Slot optocoupler is also often called direct photoelectric sensor. Its working principle is to realize the judgment of on and off through the blocking and conduction of infrared emission light and the change of current induced by infrared receiving tube. Optocoupler has the advantages of small volume, long service life, wide working temperature range and strong anti-interference performance. It has the characteristics of no contact and complete electrical isolation between input and output, so it has been widely used in various electronic equipment.
