Choice of PCBoard or wire mountings
OPB820
OPB821Z
Description:
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.
Devices are offered with 0.275” (6.96 mm) lead spacing for PCBoard mounting (OPB820) or 24” (609 mm) 26 AWG wire
leads (OPB821Z).
