These
Elevation
and Roll
Gimbal
Mounts are
ideal for
mounting:
Cameras,
antennas,
projectors,
lasers and
instrumentation
for
scanning,
tracking,
positioning
optics, and
other
applications.
Each
axis of the
gimbal mount
features:
Low backlash
worm gear
drives and
precision
"V" groove
and cross
roller
bearings for
very high
repeatability
and
positional
accuracy.
Available
with either
stepper
motors
(AU400-AE-01
pictured) or
with
three-phase
brushless
servo motors
with
Quadrature
Optical
Encoders
(AU400-AE-02)
for greater
resolution,
accuracy,
and
repeatability
as well as
higher
travel
speeds.
The
elevation
table has a
precise
pattern of
threaded
mounting
holes for
fixtures,
tooling
through
hole.
Each
AU400-ER
Series Roll
and
Elevation
Two-axis
Gimbal Mount
handles
loads to 10
kg (22 lbs),
and the
base plate
has four
handles and
accessible
predrilled
mounting
holes for
easy
integration
into new or
existing
applications.
The travel
speeds of
each axis
are 12
degrees per
second with
stepper
motors and
45 degrees
per second
with servo
motors.
Electrical
wiring is
enclosed for
protection
and
connections
are made
using 9 pin
DB-9
connectors.
The
knobs of the
stepper
motors may
be replaced
with optical
encoders for
position
verification.
An
Azimuth, Elevation and Roll Axes
version of
this gimbal
is also
available.
The
AU400-AE
Motorized
Two-axis
Gimbal
Mounts
require a
Motion
Controller
that can be
ordered as a
complete
plug-and-play
system with
joystick,
trackball,
and keypad.
