Photointerrupters(Reflective)
KODENSHI
DG-105
DIMENSIONS
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.
(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
•Detection of paper or marks
•Detection of high–speed object
•Detection of bar codes
