DESCRIPTION The HOA2498 series consists of an infrared emitting diode and an NPN silicon phototransistor (HOA2498-001, -002) or photodarlington (HOA2498-003), 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 HOA2498 series employs metal can packaged components. For additional component information see SE1450, SD1440, and SD1410.
Housing material is polyester. Housings are soluble in chlorinated hydrocarbons and ketones.
