The OPB460, OPB470, OPB480 and OPB490 series of Photologic® photo integrated circuit switches provide opꢀmum
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 mounꢀng configuraꢀons. 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 compaꢀble and can drive up
to 10 TTL loads.
Custom electrical, wire and cabling and connectors are available. Contact your local representaꢀve or OPTEK for more
informaꢀon.
