| Photointerrupters(Transmissive) K DNH OESI DG-290 DIMENSIONS The DG(c)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(c) 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 IGH H (c)SPEED RESPONSE:faster than phototransistor type USetting easy APPLICATIONS U D(c)ROM drive C 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 ... ...
