Description
The OPB700 series sensors consist of an infrared emitting diode and a NPN silicon phototransistor, mounted "side-by-side" on converging optical axes, in a black plastic housing.
The phototransistor responds to radiation from the emitter only when a reflective object passes within its field of view.

Features
• Phototransistor output
• Low profile to facilitate stacking
• Low cost plastic housing
• 4.0 inch minimum length lead wire (OPB700)
• 18.0 inch minimum length lead wire (OPB700AL)
