CNZ1122

Transmissive Photosensors (Photo Interrupters) CNZ1122, CNZ1128 Photo Interrupters CNZ1122 Unit : mm 25.0±0.35 13.0±0.3 3.0±0.2 For contactless SW, object detection Overview CNZ1122 and CNZ1128 are a photocoupler in which a visible light emitting diode is used as the light emitting element, and a high sensitivity 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.
