DG-290

Photointerrupters(Transmissive) K O D E N S H I DG-290 DIMENSIONS 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. (Unit : mm) FEATURES ¶UDIGITAL OUTPUT : directly connect to a microcomputer digital port. ¶UHYSTERESIS : stable against chattering of the object ¶U HIGH °©SPEED RESPONSE:faster than phototransistor type ¶USetting easy APPLICATIONS ¶U CD°©ROM drive ¶USensor of camera lens position ¶UEncoder of printer or scanner MAXIMUM RATINGS Item Input (Ta=2°…) 5 Symbol Rating 75 50 5 1 0.5 10 0.3 -25~+80 260 Unit mW mA V A mA V V °… °… Output Power dissipation PD F Forward current I Reverse voltage VR *1 FP I Pulse forward current c Collector current I VCEO C-E voltage E-C voltage VECO *2 Topr.
