Description:

The OPB930 and OPB940 series of Photologic? photo integrated circuit switches provide optimum flexibility for the design engineer. Building from a standard housing with a 0.125” (3.18 mm) wide slot, a user can specify the type and polarity of TTL output, discrete shell material, aperture width and either 0.350” (8.9 mm) long pins (L Series) or 24” (610 mm) AWG, UL listed wire leads (W Series).

All housings are made from an opaque grade of injection-molded plastic that minimizes the assembly’s sensitivity to both visible and near-infrared ambient radiation. Discrete shells (exposed on the parallel faces inside the device throat) are either IR transmissive plastic (for applications where aperture contamination may occur) or opaque plastic (for maximum protection against ambient light).

Electrical output can be specified as either TTL Totem Pole or TTL Open Collector, either of which can be supplied with buffer or inverter output polarity. All devices have the added stability of a built-in hysteresis amplifier.

Features:

? Choice of aperture size

? 0.125” (3.18 mm) slot width

? 0.320” (8.128 mm) lead spacing for PCBoard (side mounting)

? Data rates to 250 kBaud

Applications:

? Mechanical switch replacement

? Speed indication (tachometer)

? Mechanical limit indication
