HOA0708/0709 Reflective Sensor FEATURES • Choice of phototransistor or photodarlington output • Focused for maximum response • Ambient light and dust protective filter • Adjustable mounting slot INFRA-56.TIF DESCRIPTION The HOA0708/0709 series consists of an infrared emitting diode and an NPN silicon phototransistor (HOA0708- 001, - 011) or photodarlington (HOA0709- 001, - 011) encased side- by- side on converging optical axes in a black thermoplastic housing. The detector responds to radiation from the IRED only when a reflective object passes within its field of view. The HOA0708- 011 and HOA0709- 011 employ an IR transmissive filter to minimize the effects of visible ambient light and provide a smooth optical face which prevents the accumulation of airborne contaminants in the optical path. The HOA0708/0709 series employs plastic molded components. For additional component information see SEP8505, SDP8405, and SDP8105.
