Tolerance of ±. on all non-nominal dimensions unless otherwise specified. DSCRIPTION The QR4 reflective object sensor consists of an infrared emitting diode and an NPN photoansistor mounted side by side on a converging optical axis in a black housing. The photoansistor responds to radiation from the emitting diode only when a reflective object passes in its field of view.
