DESCRIPTION
The HOA1877 series consists of an infrared emitting
diode facing an NPN silicon phototransistor
(HOA1877- 001, - 002) or photodarlington
(HOA1877- 003) encased in a black thermoplastic
housing. Detector switching takes place whenever an
opaque object passes through the slot between emitter
and detector. The HOA1877 series has a 0.050 in.(1.27
mm) dia. detector aperture and employs metal can
packaged components. For additional component
information see SE1450, SD1440, and SD1410.
