Transmissive Photosensors (Photo Interrupters) CNA1015 Unit : mm Photo Interrupters 14.0 Overview (2.5) 0.5±0.1 (4-0.45) Features Gap width : 5 mm 2 3 1 4 2.2±0.15 ,,,, 10.0 min. 2.5 A' (10.0) Position detection accuracy : 0.3 mm (C1) Device center 10.0 CNA1015 series is a transmissive photosensor series 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. 5.0 5.0±0.15 A (4-0.45) (2.54) SEC. A-A' The type directly attached to PCB (Note) 1. Tolerance unless otherwise specified is ±0.3. 2. ( ) Dimension is reference.
