YAThe DY-ITR9606 is a Photo Interrupter Through Hole manufactured by TONYUYA. It is a RoHS compliant, precision, miniature through-hole-mounting photocoupler. This device consists of an infrared light-emitting diode coupled with a phototransistor in an inexpensive, two-lead package. The device utilizes a photosensitive element to switch output on/off states in response to a change in the condition of the light received from the infrared light emitting diode. It is designed to provide precise, reliable, and fast switching in power systems applications. It is suitable for LED control, LED pulse generation, and various other illumination systems applications.
