Assembling the magnetic tape

The magnetic tape is not included and must be
ordered separately in roll form or in specific
lengths (see Accessories on page 43).
For a complete technical description and
assembly instructions for magnetic tapes,
please see the magnetic tape user's guide on
the Internet at www.balluff.com.
Ideally, the system should include a groove or a stop edge
for the magnetic tape that clearly defines its lateral
position. If there is no stop edge, the magnetic tape can be
installed in the center below the sensor head using the
installation aid (BAM TO-ML-006-S1G, page 43).
NOTICE
Damage to the magnetic tape
Hard tools may cause damage to the magnetic surface
of the tape. Even damage that appears slight (e.g.
scratches, dents) can affect the function and linearity.
► Do not use hard tools to install the magnetic tape!
► Replace damaged magnetic tapes!
For safe operation, the magnetic tape must
protrude ≥ 5 mm from the bottom of the
housing in both end positions.

Example procedure for installing the magnetic tape using
the installation aid:
1. Fasten the installation aid (accessory) to the left or right
side of the sensor head using screws (see Fig. 4-2).
2. Thoroughly remove any oil, grease, dust, etc. (use
acetone or similar) from the mounting surface of the
tape and allow to dry completely.
3. Align the magnetic tape corresponding to the print (see
Fig. 4-1 on page 8).
4. Position the sensor head on the back end of the
magnetic tape to be applied (beginning of the
measuring range).
5. Remove the protective film on the rear end of the
magnetic tape and lightly apply the magnetic tape.
6. Remove another section of the protective film.
7. Move the sensor head forward a bit while applying the
magnetic tape flush with the installation aid (see
Fig. 4-2).
8. Lightly press the magnetic tape down by hand behind
the sensor head.
9. Optionally: To protect the magnetic tape from
mechanical and chemical influences, affix the stainless
steel cover strip (for details, see the magnetic tape
user's guide). Carefully clean the magnetic tape
beforehand (dry cloth, acetone, turpentine, mild plastic
cleaner, no benzine) to ensure the secure adhesion of
the cover strip.
10. Remove the installation aid.
