3.3 Magnetic tape mounting examples
Figure 2: Mounting example - angled protective tape
The simple mounting method with angled protective tape is only recommended in
a very protected environment.
Figure 3: Mounting example - magnetic tape, fastened on front
Figure 4: Mounting example - magnetic tape, fastened flat
There is a risk of peeling off if the environment is not protected. In these cases,
mounting methods with front or flat fastening of the magnetic tape are suitable.
Figure 5: Mounting example - magnetic tape in a slot
Mounting in a slot offers optimal protection. The slot must be deep enough that
the magnetic tape can be completely embedded inside it.
3.4 Read head mounting
WARNING
The tolerance and distance dimensions must be complied with for the entire
measuring distance. Larger deviations in mounting lead to implausible posi‐
tion values.

WARNING
As soon as the covering tape has been applied, the tape print is no longer vis‐
ible. We recommend marking the covering tape correspondingly.
NOTE
The arrow direction of the sensor print must match the arrow direction of the
tape print.
The location of the sensor compared to the magnetic tape is exactly defined. Dur‐
ing mounting, make sure that there is an air gap between the tape and sensor
over the entire measuring distance, regardless of whether the tape or the sensor
is moved. The supplied distance gage can be used as a mounting aid.
The optional mounting kit (2105618) can be used to mount the read head (cen‐
trally over the magnetic tape). The mounting kit consists of two titan screws,
safety discs, female connectors and washers each.

Figure 7: Read head mounting
1. Mount the titan screw (4), safety disc (3), washer (2) and female connector
(1) as shown.
2. Check the distance between the sensor and tape using the distance gage.
3. Secure screw with screw adhesive.
4. Tighten titan screws. Tightening torque: 2.5 ± 0.1 Nm.

Electrical installation

NOTE
Observe the corresponding operating instructions of the external drive system
or the higher-order control system for the installation of the linear encoder.
NOTE
Make sure the affected machines/systems are in a de-energized state during
mounting!
4.1 Shielding connection
NOTE
Select the area of application so that inductive or capacitative faults cannot
affect the sensor or its connecting cable.
NOTE
A suitable encoder shield connection to the ground is required for smooth
operation.
NOTE
Install the cable with strain relief. If necessary, provide a drag chain or protec‐
tive hose.
