Transmissive Photosensors (Photo Interrupters) CNZ1102,CNZ1108 Photo Interrupters Unit : mm CNZ1102 Mark for indicating LED side 25.0±0.35 13.0±0.3 3.0±0.2 Device center Overview 7.0 min. 2.5±0.2 10.0±0.2 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. 3.0±0.3 For contactless SW, object detection 2-0.45±0.2 *9.6±0.3 Features 3 6.2±0.2 2 1 *2.54±0.2 Large output current Fast response : tr, tf = 4 µs (typ.)
