Description
The HRPG series is a family of
miniature panel mount optical
encoders, also known as Rotary
Pulse Generators (RPG) and
digital potentiometers. The HRPG
is designed to be mounted on a
front panel and used as a rotary,
data-entry device. The HRPG is
very flexible for numerous
applications due to the many
configuration options available.
These options include detents or
smooth, multiple terminations,
versatile mounting capabilities,
and different shaft configurations.
The HRPG uses optical reflective
technology providing accuracy
and reliability to the encoder. An
LED emits a beam of light onto
the specular codewheel surface.
When the light strikes the surface,
it projects the image of the code-
wheel back on the photodetector,
causing the output to change. The
entire detector circuit is on one
IC, thus the part is less sensitive
to temperature and other environ-
mental variations.
Applications
Typical applications for the
Rotary Pulse Generator include
front panel instruments, audio/
visual boards, and other devices
requiring digital output from a
turning knob.
Note: Agilent Technologies
encoders are not recommended
for use in safety critical applica-
tions. Eg. ABS braking systems,
power steering, life support
systems and critical care medical
equipment. Please contact sales
representative if more
clarification is needed.
