Transmissive Photosensors (Photo Interrupters)
Photo Interrupter
Unit : mm
For contactless SW, object detection Outline
ON1109 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.
