Transmissive Photosensors (Photo Interrupters) CNZ1122, CNZ1128 Photo Interrupters Unit : mm CNZ1122 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 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. 3.0±0.3 For contactless SW, object detection 2-0.45±0.2 *9.6±0.3 2-ø3.2±0.2 19.0±0.2 2 3 6.2±0.2 Features Highly precise position detection : 1.2 mm *2.54±0.2 Fast response : tr, tf = 6 µs (typ.)
