Transmissive Photosensors (Photo Interrupters) ON1105 Photo Interrupter Unit : mm Mark for indicating LED side 25.0±0.35 14.3±0.3 3.0±0.2 A A' Highly precise position detection : 0.3 mm Fast response : tr, tf = 6 µs (typ.) 4- 0.45±0.2 +0.1 *10.0 –0.4 7.0 min. 6.2±0.2 Features 0.5±0.1 3.0±0.2 Outline ON1105 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. Device center ,,, , 10.0±0.2 2.5±0.2 For contactless SW, object detection *2.54±0.2 SEC.
