WebA photo interrupter is a devise that is made up of a infrared led and a photo transistor with a gap between the two of them, When something is placed between the gap the light is cut and the current flow through the photo transistor is reduced or stopped. WebThe slotted optical switch, sometimes known as opto switch or optical switch but not to be confused with the optical component, is a device comprising a photoemitter (e.g. LED) and a photodetector (e.g. photodiode) mounted in a single package so that the photoemitter normally illuminates the photodetector, but an opaque object can be inserted in …
