OPTEK Technology is TS 16949:2002 certified, any changes will be consistent with TS 16949:2002 procedures.
Features:
• Data rates to 250 kBaud
• 24” minimum 26 AWG wire leads
• Choice of output configuration
• Choice of opaque or IR-transmissive shell material
• Choice of aperture
• Choice of mounting configuration
Description:
The OPB960, OPB970, OPB980 and OPB990 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. OPB960 through OPB973 have 0.425” (10.795 mm) PCBoard leads with 0.320” (8.1 mm)
spacing. OPB980 through OPB993 have 24” (609 mm) 26 AWG 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 Totem-Pole 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.

Notes:
(1) The OPB880/OPB890 series switches are terminated with 24” (609.600 mm) of 7-strand 26 AWG, UL approved insulated wire on each
terminal. Insulation colors and functions are: Anode (red), cathode (black), VCC (white), output (blue), and ground (green). Custom
wire lengths and/or colors are available. Contact your local representative or OPTEK for details.
(2) Normal application would be with light source blocked, simulated by IF = 0 mA.
(3) All parameters are tested using pulse techniques.
