Transmissive Optoschmitt Sensor
• Direct TTL interface
• Buffer or inverting logic available
• Three device output options
• Four mounting configurations
• Choice of detector aperture
• 0.125 in.(3.18 mm) slot width
The HOA696X/697X series consists of an infrared
emitting diode facing an Optoschmitt detector encased
in a black thermoplastic housing. Detector switching
takes place whenever an opaque object passes through
the slot between emitter and detector. The
photodetector consists of a photodiode, amplifier,
voltage regulator, Schmitt trigger and various output
configurations. The user can choose from available
options: (1) detector aperture, (2) mounting tab
configuration, (3) detector output configuration, and (4)
The HOA696X series 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 HOA697X series employs an opaque polysulfone
housing with aperture openings for use in applications
in which maximum rejection of ambient light is
important, and situations in which maximum position
resolution is desired. The HOA696X/697X series
employs plastic molded components. For additional
component information see SEP8506 and SDP8XX4.
Housing material is polysulfone. Housings are soluble in
chlorinated hydrocarbons and ketones. Recommended
cleaning agents are methanol and isopropanol.
Buffer - Output is LO when optical path is blocked.
Inverter - Output is HI when optical path is blocked.
