A reflective phtot-interruptor has both the emitter and detctor housed on the same side of the sensor. The emitter send off infrared light which bouces off the object surface to be picked up by the detector. Typically reflective photo-interruptors are used in industrial applications and productions lines as counters. Increasingly small SMD reflective sensors are used in mobile devices as proximity sensors.
