DESCRIPTION The HOA2003 consists of an infrared emitting diode facing an Optoschmitt detector encased in a black thermoplastic housing.
The photodetector consists of a photodiode, amplifier, voltage
regulator, Schmitt trigger and an
NPN output
transistor with 10 kì (nominal) pullup resistor.
The buffer logic provides a high output when the optical path is clear, and a low output when the path is interrupted.
The HOA2003 utilizes an IR transmissive polysulfone housing which featu...
