HOA1872 Description
The HOA1872 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1872- 001, - 002, - 011, - 012) or photodarlington (HOA1872- 003, - 013) encased in a black thermoplastic housing. Detector switching takes place wherever an opaque object passes through the slot between emitter and detector. The HOA1872- 001, - 002 and - 003 have a 0.050 in.(1.27 mm)dia.
