The figure shows the two permeating interrupter structures.Their light-emitting and optical components are separated by a certain interval, and the middle is groove for objects to get through.When the element objects get through, the radiation from light emitting device shines on the optical devices directly, and the optical signal is output as electrical signal. When there are objects inside the interrupter, the radiation of light emitting devices will be blocked, then there is no light from the optical devices, and there is no output signal accordingly.This will identify whether or not there is object in it.Permeating optical interrupter is mainly used for optical control and optical measurement circuits, and can also be used to detect the existence of objects, direction of their movement and speed measurement .
