OPB821
Description:
Each OPB820 and OPB821 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” (610 mm) 26
AWG wire leads (OPB821).
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
Applications:
• Non-contact object sensing
• Assembly line automation
• Machine automation
• Equipment safety
• Machine safety
