4.1.1
Mounting the magnetic and cover strip
The magnetic tape can be mounted on a suitable flat surface chosen by the customer parallel to
the direction of movement on the fixed part of the system. The following criteria must be met:
Average roughness value R
a
≤ 3.2
µm
Height deviation (parallelism) to the direction of travel of the encoder: ≤ 0.1
mm
Lateral parallelism deviation to the direction of travel of the encoder: ≤ 0.2
mm (ideally use
a reference edge)
The magnetic tape and the cover strip are provided with an adhesive film covered by a
protective tape.
Note:
Only remove the protective tape shortly before or during assembly!
Assembly steps:
Thoroughly clean the surface
[1]
on which the tape is to be mounted with alcohol or
isopropanol.
Note:
The mounting surface for the magnetic tape must be absolutely clean, dry and free of grease!
This is the only way to ensure a reliable adhesive bond!
Stick on the magnetic tape
[2]
and press it on using a mounting roller with a force of
approx. 250
N/cm
2
. Make sure that the tape is neither compressed nor overstretched.
Clean the surface of the magnetic tape as described above.
Stick the cover strip
[3]
onto the magnetic tape. Make sure that there are no bubbles under
the tape when gluing. Press on the cover strip with a mounting roller with a force of approx.
250
N/cm
2
.
The magnetic tape and the cover strip are mounted.
Note:
The adhesive strength is created under pressure. The final strength is achieved after approx.
48 hours at room temperature.
4.1.2
Mounting the encoder
Attach the encoder
[4]
to the moving part of the system so that the reference edge of the
encoder is flush with the edge of the magnetic tape. The reference edge of the encoder is
identified by a mark on the front.
The encoder is mounted.
Note:
The distance between the cover strip and the encoder must be 0.2 ±0.1
mm. The use of a
feeler gauge is recommended for setting the correct distance.
Make sure that the minimum cable bending radius of 40
mm is not undercut!
