Description:
The OPB120 through OPB123 devices consist of an infrared emitting diode and a Photologic® sensor (which is a
monolithic integrated circuit that incorporates a linear amplifier and a Schmitt Trigger). The OPB120 series have
an LED and Photologic® sensor mounted on opposite sides of a 0.080” (2.03 mm) wide gap of an opaque
housing. The OPB12_A series have a molded 0.040” (1.02 mm) wide apertures located over both the emitter and
the Photologic® sensor. The OPB12_B seriesseries have a molded 0.040” (1.016 mm) wide apertures located
over the emitter and 0.010” (0.254 mm) over the Photologic® sensor. All devices in this series have the added
stability utilizing hysteresis built into the amplification circuitry.
The electrical output can be specified as either buffered Totem-Pole (OPB 120A, OPB120B), buffered Open-
Collector (OPB121A, OPB121B), Inverted Totem-Pole (OPB122A, OPB122B), or Inverted Open-Collector
(OPB123A, OPB123B).
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
