CNZ1122

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 as to face each other, and objects passing between them are detected. Features Highly precise position detection : 1.2 mm Fast response : tr, tf = 6 µs (typ.)
