CNZ1179

Transmissive Photosensors (Photo Interrupters) CNZ1179 Photo Interrupter Unit : mm For contactless SW, object detection Overview CNZ1179 is 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. 2.2±0.2 Mark for indicating LED side 13.0±0.3 5.0±0.2 6.2±0.2 2-R0.5 0.45±0.1 7.0 min. 10.0±0.3 2.0±0.2 Features Highly precise position detection : 0.3 mm Wide gap between emitting and detecting elements, suitable for thick plate detection Fast response : tr, tf = 6 µs (typ.)
