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.
Housing material is polycarbonate. Housings are
soluble in chlorinated hydrocarbons and ketones.
Recommended cleaning agents are methanol and
isopropanol.
