3 Product Description
M-232 Linear Actuator MP105E Version: 1.2 9
Component Task Supplied by or available from
PI
Cables

Peripheral control equipment
to controller:
Ensures the data
communication.

Controller to actuator:
Ensures the data
communication and the
power source of the actuator.

Transmission cable between
PC and controller.
Included in the scope of
delivery of PI controllers.

Transmission cable between
controller and actuator:
Part of the actuator or
included in the scope of
delivery of the piezo actuator.
Mechanical structure Ensures among other things the
secure fixation of the actuator
and thus a high repeatability. Only mounting nut (for
mechanical connection) included
in the scope of delivery of the
actuator.
Mechanical coupling Establishes the connection
between the actuator and the
load (pusher with a separate end
piece, depending on the model). Also in case exchangeable parts
can be used, all options are
included in the scope of delivery
of the actuator (e.g. end pieces).
Load Part to be driven. This is to be
moved in your application. -
If a motor controller card is used, the "controller" component and the connection
between the peripheral control equipment and the controller ("cable") are physically
inside of the PC.
3.2 Features and Applications
The M-232 is a compact and cost-effective linear actuator with a 17 mm travel range
and a length that could be reduced with a folded drive to only 72 mm. As a result of
the combination of a backlash-free preloaded DC gear motor with high-resolution
rotary encoder and an extremely low-friction and zero-backlash design, the M-232
achieves minimum incremental motions of 100 nm and velocities of up to 2.5 mm/s. A
design with a stepper motor is also on offer.
Integrated limit switches as well as line drivers enable easy installation in automation
solutions and protect the mechanical system of the actuator.
The M-232 can be installed, for example, on the fiber positioning system /
micropositioning stage M-105 or M-106 instead of a micrometer screw or a piezo
drive.
