| HOA1405 Reflective Sensor FEATURES * Phototransistor output * Focused for maximum response * Ambient light and dust protective filter INFRA-68.TIF DESCRIPTION The HOA1405 series consists of an infrared emitting diode and an NPN silicon phototransistor encased sideby-side on converging optical axes in a black thermoplastic housing. The phototransistor responds to radiation from the IRED only when a reflective object passes within its field of view. The HOA1405 series employs an IR transmissive filter to minimize the effects of visible ambient light and to provide a smooth optical face which prevents the accumulation of airborne contaminants in the optical path. The HOA1405 series contains plastic molded components. For additional component information see SEP8505 and SDP8405. Housing material is polyester. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
