Transmissive Optoschmitt Sensor
HOA2001
DESCRIPTION
FEATURES
Direct TTL interface
Buffer logic
0.060 in.(1.52 mm) dia. detector aperture
0.120 in.(3.05 mm) slot width
0.050 in.(1.27) offset pin circle detector eads
The HOA2001 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 k (nominal) pull-
up resistor. The buffer logic provides a high output
when the optical path is clear, and a low output when
the path is interrupted. The HOA2001 employs plastic
molded components. For additional component
information see SEP8506 and SDP8600.
Housing material is polyester. Housings are soluble in
chlorinated hydrocarbons and ketones. Recommended
cleaning agents are methanol and isopropanol.
