The DG290 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.

DIGITAL OUTPUT : directly connect to a microcomputer
digital port.
HYSTERESIS : stable against chattering of the object
