Photointerrupters(Transmissive)
KODENSHI
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– c o m p a c t
size,requires little space.
(Unit : mm)
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
