DG-112
KODENSHI
The DG–112 carrying a unique hysteresis transistor
(BAMBIT)developed by KODENSHI CORP. facililates
digital output by means of two leads.
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
