Transmissive Photosensors (Photo Interrupters) CNA1007H Photo Interrupter Unit : mm For contactless SW, object detection (3.2) 1.65 Features Position detection accuracy : 0.3 mm 1.5±0.15 (C1) ,,, Device Center 3.5±0.5 10.0 2.5 1.3 CNA1007H is a transmissive photosensor 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. 6.0 5.0 14.0 5.0±0.15 A A' (10.0) +0 φ1.2 –0.1 Gap width : 5 mm (4-0.45) 0.5±0.1 Overview (4-0.45) (2.54) SEC.
