Photointerrupters(Reflective) KODENSHI DG-105 DIMENSIONS (Unit : mm) The DG–105 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 o m p a c t 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 •Detection of paper or marks •Detection of high–speed object •Detection of bar codes MAXIMUM RATINGS Item Input Output Power dissipation Forward current Reverse voltage Collector current C-E voltage E-C voltage Operating temp.*1 Soldering temp.*2 (Ta=25℃) Symbol Rating Unit PD IF VR Ic VCEO VECO Topr.
