Panasonic CNA1301H Datasheet
Transmissive Photosensors (Photo Interrupters)
CNA1301H
Photo Interrupter
For contactless SW, object detection
Overview
CNA1301H is an ultraminiature, highly reliable transmissive
photosensor in which a high efficiency GaAs infrared light emitting
diode chip and a high sensitivity Si phototransistor chip are integrated
in a double molded resin package.
Features
Ultraminiature : 3.8 × 4.2 mm (height : 4.2 mm)
Highly precise position detection : 0.15 mm
Gap width : 1.4 mm
Support for thin equipment (permits direct mounting on printed
circuit board
