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
