OPB940W51 [TT Electronics]

The OPB930 and OPB940 series are Photologic® photo integrated circuit switches built from a standard housing with a 0.125” (3.18 mm) wide slot. Users can specify TTL output type and polarity (Totem Pole or Open Collector, with buffer or inverter), discrete shell material (IR transmissive or opaque), aperture width, and termination (pins for L Series or wires for W Series). Housings are made from opaque injection-molded plastic to minimize sensitivity to ambient radiation. Discrete shells are either IR transmissive plastic (for contamination-prone applications) or opaque plastic (for maximum ambient light protection). All devices feature a built-in hysteresis amplifier for stability. Custom electrical, wire, cabling, and connectors are available.
