CNZ1215
Photo Interrupter
For contactless SW, object detection
Overview
CNZ1215 is a photocoupler in which a visible light emitting diode
is used as the light emitting element, and a high sensitivity Darlington
phototransistor is used as the light detecting element. The two
elements are arranged so as to face each other, and objects passing
between them are detected.
