Description:

The OPB120B consists 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 OPB120B has an LED and Photologic® sensor mounted on

opposite sides of a 0.080” (2.03 mm) wide gap of an opaque housing. The OPB120B has a molded 0.040” (1.016 mm) wide

aperture 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 is a buffered Totem-Pole.

Custom electrical, wire and cabling and connectors are available.
