Data rates to 250 kBaud

Low power consumption

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.

Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more

information.

Applications:



Mechanical switch replacement



Speed indication (tachometer)



Mechanical limit indication



Edge sensing
