1 / 2 page - 1- DG-290 Photointerrupters(Transmissive) KODENSHI Forward voltage Reverse current Peak wavelength Operating supply voltage rang Low level output voltage High level output voltage Peak wavelength Threshold input current *4 Hysteresis *5 L →H propagation time H →L propagation time Rise time Fall time The DG–290 carrying a unique hysteresis transistor (BAMBIT)developed by KODENSHI CORP.facililates digital output bymeans of two leads.This digital photointerrupter,because of its ultra– compact size,requires little space. FEATURES •DIGITAL OUTPUT : directly connect to a microcomputer digital port. •HYSTERESIS : stable against chattering of the object •HIGH–SPEED RESPONSE:faster than phototransistor type •Setting easy APPLICATIONS •CD–ROM drive •Sensor of camera lens position •Encoder of printer or scanner DIMENSIONS (Unit : mm) (Ta=25℃) ELECTRO-OPTICAL CHARACTERISTICS IF=20mA VR=5V IF =20mA VCC =3V,IF =0mA,RE =100k Ω VCC =3V,IF =14mA,RE =100k Ω VCC=3V,RE=100kΩ VCC=3V,RE=100kΩ VCC =3V,IF =14mA,RE =100k Ω Item Typ. 1.2 940 0.25 2.65 880 6.0 0.85 10 25 2.5 15 VF IR λp VCC VOL VOH λp IFLH IFHL/IFLH tPLH tPHL tr tr 2.0 2.5 1.4 10 5.5 0.4 12.0 V μA nm V V V nm mA μsec. μsec. μsec. μsec.
