· Dust protective housing
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 features
smooth optical faces without external aperture
openings; this feature is desirable when aperture
blockage from airborne contaminants is a possibility.
The detector has a 0.010 in.(.254 mm) x 0.040 in.(1.02
mm) vertical aperture which is ideal for use in
applications in which maximum position resolution is
desired. The HOA2003 employs plastic molded
components. For additional component information see
SEP8506 and SDP8600.
Housing material is polysulfone. Housings are soluble in
chlorinated hydrocarbons and ketones. Recommended
cleaning agents are methanol and isopropanol
