| Transmissive Photosensors (Photo Interrupters) 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.
