M-230 Precision Linear Actuator
Non-Rotating Tip, Limit Switches, Stroke to 25 mm
M-230 are ultra-high-resolution
linear actuators providing lin-
earmotionupto25mmwith
sub-micron resolution in a
compact package. They consist
of a micrometer with non-rotat-
ing tip driven by a 2-phase
stepper motor or a closed-loop
DC motor / gearhead combina-
tion with motor-shaft-mounted,
high-resolution encoder.
Non-Rotating Tip
Compared to conventional
rotating-tip micrometer drives,
the non-rotating-tip design
offers several advantages:
L52159 Elimination of torque-
induced positioning errors
L52159 Elimination of sinusoidal
motion errors
L52159 Elimination of wear at the
contact point
L52159 Elimination of tip-angle-
dependent wobble
High Accuracy & Long Life
M-230 actuators provide a cost-
effective solution for heavier-
duty industrial and OEM envi-
ronments. They feature ex-
tremely low-stiction, low-fric-
tion construction, allowing for
minimum incremental motion
as low as 50 nanometers and
speeds up to 2 mm/sec.
Limit and Reference Switches
For the protection of your
equipment, non-contact Hall-
effect limit and reference
switches are installed. The
direction-sensing reference
switch supports advanced
automation applications with
high precision.
Integrated Line Drivers
All actuators include an inte-
gral 0.5 m cable with 15-pin
sub-D connector and come
with a 3 m extension cable. On
the DC servo versions, the con-
nector features integrated line
drivers for cable lengths up to
10 meters between actuator
and controller.
High-Load Versions
For higher loads and travel
ranges refer to the M-235 (see
p. 1-50) and M-238 (see p. 1-52).
A screw-in ball tip and a flat tip
are included.
