CNZ1122 - Panasonic Semiconductor

CNZ1122 Photo Interrupters

Transmissive Photosensors (Photo Interrupters) CNZ1122, CNZ1128 Photo Interrupters 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.
