OPB122A [TT Electronics]

These optical sensors feature an infrared emitter and Photologic® sensor mounted in an opaque plastic housing with a low profile. They utilize hysteresis in the amplification circuitry for stability. Output configurations include buffered Totem-Pole (OPB120A/B), buffered Open-Collector (OPB121A/B), Inverted Totem-Pole (OPB122A/B), and Inverted Open-Collector (OPB123A/B). The series offers different aperture widths: OPB12_A has 0.040" (1.02 mm) apertures over both emitter and sensor, while OPB12_B has 0.040" (1.016 mm) over the emitter and 0.010" (0.254 mm) over the sensor. Custom electrical, cabling, and connector options are available.
