Description:
The OPB460, OPB470, OPB480 and OPB490 series of Photologic® photo integrated circuit switches provide optimum flexibility for the design engineer. Building from a standard housing with a 0.125” (3.180 mm) wide slot, a user can specify the type and polarity of TTL output, discrete shell material, aperture width and choice of mounting configurations. OPB460 through OPB473 have 0.425” (10.795 mm) PCBoard leads with 0.320” (8.1 mm) spacing. OPB480 through OPB493 have 24” (609 mm) 26 AWG wires (UL approved wires).
All devices in this series exhibit performance over supply voltages ranging from 4.5 V to 16.0 V, and may be specified as buffered or inverted with 10 kW Pull-up or Open Collector output. Devices are also TTI/LSTTL compatible and can drive up to 10 TTL loads.

Features:
• Choice of pins or wires mounting configuration
• Choice of aperture
• Choice of output configuration
• Choice of opaque or IR transmissive shell material
• Data rates to 250 kBaud
• Low power consumption

Applications:
• Mechanical switch replacement
