Description
The HEDS-5700 series is a family
of low cost, high performance,
optical incremental encoders with
mounted shafts and bushings. The
HEDS-5700 is available with
tactile feedback for hand operated
panel mount applications, or with
a free spinning shaft for applications requiring a pre-assembled
encoder for position sensing.
The encoder contains a collimated
LED light source and special
detector circuit which allows for
high resolution, excellent encoding performance, long rotational
life, and increased reliability. The
unit outputs two digital waveforms which are 90 degrees out of
phase to provide position and
direction information. The
HEDS-5740 Series provides a
third Index Channel.

applications requiring digital
information from a manually
operated knob. Typical front
panel applications include
instruments, CAD/CAM systems,
and audio/video control boards.
Applications
The HEDS-5700 without static
drag (free spinning) is best suited
for low speed, mechanized
The HEDS-5700 with the static
drag option is best suited for
operations. Typical applications
are copiers, X-Y tables, and
assembly line equipment.
MOTION SENSING
AND CONTROL
The HEDS-5700 is quickly and
easily mounted to a front panel
using the threaded bushing, or it
can be directly coupled to a motor
shaft (or gear train) for position
sensing applications.
