: Each OPB820 and OPB821Z device consists of an infrared emitting diode (LED, 890 nm center wavelength) and a NPN silicon phototransistor mounted in a low-cost black plastic housing on opposite sides of an 0.080” (2.03 mm) wide slot.
Each device in this series has a 0.040” (1.02 mm) wide aperture located in front of the infrared diode.
Phototransistor switching occurs when an opaque object passes through the slot.
