| Transmissive Photosensors (Photo Interrupters) CNZ1102,CNZ1108 Photo Interrupters CNZ1102 Unit : mm 25.00.35 13.00.3 3.00.2 For contactless SW, object detection Overview CNZ1102 and CNZ1108 are a photocoupler in which a high efficiency GaAs infrared 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. Mark for indicating LED side Device center 7.0 min. 2.50.2 10.00.2 2-0.450.2 *9.60.3 Features Position detection accuracy : 1.2 mm Large output current Fast response : tr, tf = 4 s (typ.) (CNZ1102) 6 s (typ.)
