Description
Features
The HRPG series is a family of miniature panel mount • Miniature size
opticalencoders,alsoknownasRotaryPulseGenerators
• Smooth turning and detented options
(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
• Multiple mounting bracket options
• Uses optical reflective technology
numerous applications due to the many configuration • Quadrature digital output
options available. These options include detents or
smooth, multiple terminations, versatile mounting
capabilities, and different shaft configurations.
• Small footprint for versatile mounting
• TTL compatible
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 codewheel 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 environmental 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: Avago Technologies encoders are not
recommended for use in safety critical applications.
Eg. ABS braking systems, power steering, life support
systems and critical care medical equipment. Please
contact sales representative if more clarification is
needed.
