Explore the workings of optocouplers, their structure, importance, applications, and types, and how they ensure safe electrical signal transfer. In this guide, you'll learn how they work and how you can use one in your own projects. Optocouplers are very useful when you need to isolate different sections of a circuit, for example in power. Optocouplers, also known as opto-isolators, uses infrared light to transfer electrical signals between two electrically isolated circuits and are commonly classified by their photosensitive output device What is an Optocoupler? An optocoupler (also called an opto-isolator, photo-coupler, or optical. In other words, an optocoupler is used to transfer electrical signals between two circuits optically.
