Assembling the measuring system

NOTICE
Interference in function
Improper assembly of the magnetic tape and sensor
head may impair function of the position measuring
system and lead to increased wear or damage to the
system.
► All permissible distance and angle tolerances (see
section 4.1) must be strictly complied with.
► The sensor head may not come into contact with
the magnetic tape over the entire measuring range.
Contact must also be avoided if the magnetic tape is
covered by a cover strip (optional).
► The position measuring system must be installed in
accordance with the indicated degree of protection.
External magnetic fields change the functional properties.
Magnetic fields with ≥ 1 mT reduce the precision of the
system, magnetic fields of ≥ 30 mT destroy the magnetic
tape. The functionality of the system is no longer
ensured.
► Direct contact with magnetic clamps or other
permanent magnets must be avoided.
No forces may be exerted on the plug or cable on the
housing.
► Provide the cable with a strain relief.
4.2.1

Assembling the magnetic tape

(Magnetic tape is not included in the scope of delivery.)
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 the 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 18).
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.
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
quick rubbing alcohol 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. 3-2 on page 7).
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
instructions). 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.
