What is photo interrupter?
A photo interrupter is an opto-electronic sub-system composed of an optical emitter and a detector with amplifier, typically with only logic level electrical output. The emitter uses simple beam forming optics to project light onto the detector, both elements being mechanically positioned with a fixed gap between them. The detector then can be used to sense if the free path between the emitter and the detector is blocked. When the beam path is blocked by an opaque object the logic output state switches, thus providing a non-contact presence sensor for automation. Transition edges can be used to trigger events, such as snapping a digital image with strobe illumination during high volume manufacturing to inspect aspects of production quality.
