The is a Reflective Object Sensor that consists of a gallium arsenide infrared emitting diode and an NPN silicon phototransistor. On each sensor, the emitting diode and detector are mounted side-by-side on parallel axes. A black plastic sleeve is attached and filled with encapsulating epoxy to cover the emitter and detector. The package contains an internal barrier which prevents diode emissions from reaching the sensor directly.
