1. Warrant information
Read this document carefully before mounting and start-up. For your own safety and operational reliability, observe all
warnings and notes.
Your product has left our factory in certified and ready for operation status. The specifications given and the information
on the type plate apply as a condition for operation.
Warranty claims only apply to products of ipf electronic gmbh. When used in conjunction with third-party products,
there is no warranty claim for the entire system.
Repairs may only be carried out at the factory. If you have any further questions, please do not hesitate to contact ipf
electronic gmbh.
2. Identification
Magnetic strip: Magnetic strip is available in 10mm (part number AM000085) and 20mm (part number AM000119)
widths.

3. Mechanical assembl
The installation may only be carried out in accordance with the specified IP protection class. If necessary, the system
must be additionally protected against harmful environmental influences, e.g. splash water, solvents, dust, impacts,
vibrations, strong temperature fluctuations.
3.1 Mounting the magnetic Strip
The mounting must be flat to the mounting surface or the distance to be measured. Waviness always reduces the
measuring accuracy.
For technical reasons, the length must be at least 13 mm longer than the measuring section.
Wherever no suitable mounting of the magnetic Strip is possible due to insufficient mounting options, the magnetic
strip AM000085 (10mm width) can be mounted in a section rail (AM000050) available as an accessor . This creates a
compact magnetic strip unit.
Attention! To achieve optimum bonding, all anti-adhesive foreign substances (oil, grease, dust, etc.) must be removed
by cleaning agents which evaporate as far as possible without leaving any residue. Suitable cleaning agents
include ketones (acetone) or alcohols, which are offered as quick cleaners by the companies Loctite and
3M, among others. The surfaces to be bonded must be dry and the highest possible contact pressure must
be applied. The optimal bonding temperature is between 20°C and 30°C in dry rooms.
Tip: When bonding long tapes, the protective film of the adhesive tape should be removed via a short section to fix
the tape. The tape is then aligned. Now the protective film can be pulled out sideways via the remaining length
while simultaneously applying pressure to the tape. (A wallpaper pressure roller can be used as an aid).
Assembl steps
 Clean the mounting surface (1) carefully.
 Remove the protective film (2) of the adhesive tape (3) from the mag-
netic strip.
 Stick on the magnetic strip (4).
 Clean the magnetic strip surface carefully.
 Remove the protective film (6) of the adhesive tape from the cover strip
(5).
 Stick on the cover strip (let it overlap slightly at both ends).
 Secure the overlapping ends of the cover strip against detachment.
Attention! Avoid interference from magnetic fields. In particular, no magnetic fields (e.g. holding magnets or other
permanent magnets) may come into direct contact with the magnetic strip. In de-energized status,
movements or adjustments of the magnetic sensor are not recognized and detected by the subsequent
electronics.

Mounting examples
The simple mounting method, using a beveled protective tape
(Fig. 2), is only recommended in a very protected environment.
In unprotected environments, there is a risk of peeling. In such
cases, mounting methods as shown in Figs. 3 and 4 are more
suitable.
Optimum protection is provided by mounting in a groove (Fig.
5), which should be deep enough to allow the magnetic strip to
be fully embedded in it.
3.2 Mounting the magnetic sensor
The magnetic sensor can be mounted by using 2 M3 screws
via the ø3.5mm through holes. It is recommended to use the
enclosed fixing screws and spring washers. The maximum
tightening torque is 0.25Nm!
 Cables must be laid in such a way that there is no risk of
damage from drafts or other machine parts. If necessary,
use a drag chain or sheath and provide strain relief.
 Ensure correct alignment on the direction of counting
(Fig. 6). This is irrelevant if the direction of counting can
be reversed in the electronic evaluation.
 Observe the distance dimensions between sensor and
magnetic strip as well as the angle tolerances, these
must be complied with via the entire measuring dis-
tance! (Fig. 6)
 Maximum traverse speed < 25m/s.
 The maximum lateral offset depends on the magnetic
strip width:
o AM000085 (10mm wide): 2mm
o AM000119 (20mm wide): 5mm

4. Electrical connection
 Wiring work may only be carried out disconnected!
 Before switching on, check all line connections and plug connections.
 Tinned strands must not be used in conjunction with screw terminal connections.
Notes on interference immunit
All contactors are protected against external disturbing influences. However, the place of installation must be selected
in such a way that inductive or capacitive interference cannot affect the sensor or its connection cable! Disturbing in-
fluences (e.g. from switching power supplies, motors, pulsed controllers or contactors) can be reduced by suitable cable
routing and wiring.
Required Action:
 Only use shielded cable. Apply the cable shield on both sides. Wire cross-section of the lines min. 0.14mm², max.
0.5mm².
 The shielding and ground (0V) must be wired in a star configuration and over a large area. The connection of the
shielding to the equipotential bonding must be made over a large area (low impedance).
 The system must be installed at as great a distance as possible from lines that are subject to interference; if neces-
sary, provide for this. Avoid routing cables parallel to power lines.
 Contactor coils must be wired with spark suppressors.
Power suppl
The voltage values depend on the sensor version and can be found in the delivery documents and on the type plate.
(e.g.: UB = 24V DC ± 20%)
5. Maintenance
Clean the surface of the magnetic strip from time to time with a soft cloth if it is heavily soiled by dust, chips, moisture,
etc.
6. Error handling
Typical errors that occur during installation and operation:
 The magnetic strip was mounted incorrectly /active side down (chap. 3.1).
 The supplied cover strip was not used to protect the magnetic strip. The cover strip must be non-magnetizable.
 The sensor is not or not correctly connected (wiring diagram, chap. ).
 The distance tolerance between sensor and magnetic strip was not complied with via the entire measuring distance,
the sensor grazes on the magnetic strip (Fig. 6).
 Cable interruption / disconnection due to sharp edges / crushing.
 The sensor is mounted with the active side facing away from the belt (Fig. 6). The active side is additionally marked
with the "Tape side" sticker.
 The sensor has not been aligned according to Fig. 6
