5 Installation
M-232 Linear Actuator MP105E Version: 1.2 21

You have made a suitable hole with internal thread in the mechanical
mounting for each of the planned mounting screws. The hole is positioned so
that the mounting screw can engage vertically in the circumferential groove of
the mounting shaft after installation. The position of the circumferential groove
can be found in the above illustration of the components and installation
dimensions.
Tools and accessories

At least one suitable mounting screw, e.g. M2 grub screw. To be able to
engage in the groove optimally, the screw should have an angled end instead
of a flat end.

Suitable Allen wrench or screwdriver for the mounting screw(s).
Installing the actuator in a mechanical mounting
1. Insert the actuator in the mounting of your application.
2. Place the groove of the mounting shaft precisely across the holes for
mounting screws.
3. Screw all mounting screws into the threaded hole of the mounting with a
maximum torque of 0.3 Nm each time until you feel resistance.
4. Check that the actuator is correctly fitted in the mounting.
5.3 Installing the Actuator in a Micropositioning Stage
The M-232 is suitable, e.g., for installation in a PI micropositioning stage / -fiber
positioning system of the type M-105 or M-106.
NOTICE
Overtightened mounting screws!
Overtightening the mounting screws can damage the mounting shaft of the linear
actuator and hinder the motion of the pusher. This reduces the positioning accuracy.

Tighten the mounting screws to a maximum torque of 0.3 Nm.
Prerequisites

You have read and understood the General Notes on Installation (p. 15).

If necessary: you have disassembled the drive of the micropositioning stage
(e.g. micrometer screw or piezo drive).
