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. FATURS Photoansistor output No contact surface sensing Daylight filter on the sensor mitter = 94 nm Fairchild Semiconductor Corporation DS54 9// OF 6
