Photointerrupters(Transmissive)
KODENSHI
DG-290
DIMENSIONS
The DG鈥?90 carrying a unique hysteresis transistor
(BAMBIT)developed by KODENSHI CORP.facililates
digital output bymeans of two leads.This digital
photointerrupter,because of its ultra鈥?c o m p a c t
size,requires little space.
(Unit : mm)
FEATURES
鈥IGITAL OUTPUT : directly connect to a microcomputer
digital port.
鈥YSTERESIS : stable against chattering of the object
鈥IGH鈥揝PEED RESPONSE:faster than phototransistor
type
鈥etting easy
APPLICATIONS
鈥D鈥揜OM drive
鈥ensor of camera lens position
鈥ncoder of printer or scanner
