Description
The OPB701 series consist of an infrared emitting diode and a NPN silicon photodarlington mounted "side-by-side" on converging optical axes, in a black plastic housing. The photodarlington responds to radiation from the emitter only when a reflective object passes within its field of view.

FEATUREs
• Photodarlington output
• Low profile to facilitate stacking
• Low cost plastic housing
• 4.0 inch minimum length lead wire (OPB701)
• 18.0 inch minimum length lead wire (OPB701AL)
