DESCRIPTION
The QRB1113/1114 consists of an infrared emitting diode and an NPN silicon phototransistor mounted side by side on a converg-
ing optical axis in a black plastic housing. The phototransistor responds to radiation from the emitting diode only when a reflective
object passes within its field of view. The area of the optimum response approximates a circle .200" in diameter.
FEATURES
• No contact surface sensing
• Phototransistor output
• Focused for sensing specular reflection
• Daylight filter on photosensor
• Dust cover
