Photologic® Slotted Optical Switch
OPB460, OPB470, OPB480, OPB490 Series
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
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.
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
