DESCRIPTION The HOA1870 series consists of an infrared emitting diode facing an
NPN silicon photo
transistor (HOA1870- 031) or photodarlington (HOA1870- 033) encased in a black thermoplastic housing.
Detector switching takes place whenever an opaque object passes through the slot between emitter and detector.
A minimum of 18.
