ON1105

Transmissive Photosensors (Photo Interrupters) ON1105 Photo Interrupter Unit : mm For contactless SW, object detection 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.
