ST-1MLAR2・ST-1MLBR2
DIMENSIONS
(Unit : mm)
The ST-1MLAR2 and 1MLBR2 are high-sensitivity
NPN silicon phototransistors mounted in a TO-18
Type header with black epoxy encapsulation. With
daylight filter the phototransistor is sensitive only to
infrared rays.
FEATURES
•Wide angular response
•Relatively low-cost against metal can package
•Low profile package
•With daylight filter
APPLICATIONS
•Remote control sensors
•Card readers
•Optical switches
