OPB932W51Z [Optek]

Building from a standard housing with a 0.125” (3.18 mm) wide slot, users can specify TTL output type and polarity, discrete shell material, aperture width, and termination (pins or wires). Housings are opaque injection-molded plastic to minimize sensitivity to ambient light. Shells are either IR transmissive or opaque. Output configurations include TTL Totem Pole or Open Collector with buffer or inverter polarity. All devices feature a built-in hysteresis amplifier.
