| E2P0063-37-X2 PHOTO SENSOR UNITS This version: Jan. 1998 Previous version: May. 1997 OPU813, OPU813R electronic components OPU813, OPU813R Reflector-Type Photo Interrupter GENERAL DESCRIPTION The OPU813 and OPU813R are reflector-type photo interrupters that have been developed for reading 0.17mm bar codes. FEATURES * Aspherical lenses control a bundle of rays accurately. * Integrated molding of the lens with the case yields good alignment accuracy and small dispersions of the characteristics. * The Connector is integratedly molded with the case and is compatible with an IL-Y type connector made by Japan Aviation Electronic Ind., Ltd. * Assembling without an adhesive and solder achieves the high quality. * Lens part is not directly exposed to the external environment. Therefore, paper powder scarcely deposits on the reading part. * S/N ratio is improved by optically separating the light emitting part and receiving part with light shielding wall. APPLICATIONS * * * * Bar code reader Paper edge sensor (Printer, Plotter) Detector of small electronic components such as a chip resistor, chip capacitor, etc. Detection of the front and back sides of small electronic components 1/11 PHOTO SENSOR UNITS OPU813, OPU813R PIN CONFIGURATION OPU813, OPU813R 10.00.15 5.0 1.2 1.2 1.2 (Unit: mm) 3.0 4.0 5.00.15 4.0 2.0 7.0 1.0 qwer Pin Connection q LED Anode w LED Cathode e PTr Emitter r PTr Collector 4.0 13.00.2 4.0 1.0 13.00.3 2/11 PHOTO SENSOR UNITS OPU813, OPU813R OPTICAL LAYOUT OPU813, OPU813R LEDChip Header Case Optical path Paper Phototransistor chip Slit Light shielding wall Aspherical lens 3/11 PHOTO SENSOR UNITS OPU813, OPU813R ABSOLUTE MAXIMUM RATINGS Parameter LED Forward Current Input LED Reverse Voltage Power Dissipation Collector-emitter Voltage Output Emitter-collector Voltage Power Dissipation Operating Temperature Storage Temperature Symbol Test Condition IF VR PD VCEO VECO PC Topr Tstg -- -- 40 0 to +65 -10 to +70 Ta=25C Rating OPU813 40 5.5 60 20 5 40 OPU813R 30 5.0 60 Unit mA V mW V V mW C C ELECTRICAL CHARACTERISTICS OPU813 (Ambient Temperature Ta=25C, Tilt Angle=15C) Parameter Forward Voltage Input Output Reverse Current Peak-emission Wavelength Dark Current Photocurrent Coupled S/N Ratio Maximum-sensitivity Point Focal Depth Symbol Test Condition VF IR lP ID IP -- R DR *1 IF=40mA VR=5.5V IF=40mA VC=5V VC=5V Min. -- -- -- -- 4.5 2.5 -- -- Typ. 1.4 -- 910 -- 18 3.6 3.65 0.9 Max. 1.8 10 -- 60 60 -- -- -- Unit V mA nm nA mA -- mm mm *1 Coupled characteristics measuring method. 4/11 PHOTO SENSOR UNITS OPU813, OPU813R ELECTRICAL CHARACTERISTICS (Continued) OPU813R (Ambient Temperature Ta=25C, Tilt Angle=15C) Parameter LED Forward Voltage Input Output LED Reverse Current Peak-emission Wavelength Dark Current Photocurrent Coupled S/N Ratio Maximum-sensitivity Point Focal Depth Symbol Test Condition VF IR lP ID IP -- R DR *1 IF=20mA VR=5V IF=20mA VC=5V VC=5V Min. -- -- -- -- 1 2.5 -- -- Typ. 1.8 -- 660 -- 10 5.0 3.65 0.8 Max. 2.2 10 -- 60 30 -- -- -- Unit V mA nm nA mA -- mm mm *1 Coupled characteristics measuring method.
