REFLECTIVE OBJECT SENSOR
QRE00034
DESCRIPTION
The QRE00034 reflective object sensor consists of an infrared emitting diode and an NPN phototransistor mounted side by
side on a converging optical axis in a black housing. The phototransistor responds to radiation from the emitting diode only
when a reflective object passes in its field of view.
NOTES
1. Derate power dissipation linearly 1.33 mW/°C above 25°C.
2. RMA flux is recommended.
3. Methanol or isopropyl alcohols are recommended as cleaning agents.
4. Soldering iron tip at 1/16 (1.6mm) from housing.
5. Pulse conditions: tp = 10 µs; T = 1 ms.
6. Measured as an Eastman Kodak neutral white test card with 90% diffused reflectance as a reflecting surface.
7. 0.160 (4 mm) distance from sensor face to reflector surface.
