5 Product Features
The length measuring system LMIX22 bases on the proven LMIX encoder system. The system extends the existing
LMIX product series and offers two considerable advantages:
The resolution can be freely selected ( 0)
The sensor is also available with a unique reference pulse ( 5.1 resp. 5.2)
Overview of features:
Distance between sensor / magnetic tape up to 2.0 mm
Differential HTL or TTL Line Driver Outputs
Various resolution with 4 edge triggering available (order designation)
Repeat accuracy +/- 1 increment
Small sensor with integrated evaluation electronic (translator)
Speed proportional output of square-wave signals
Periodic index pulse every 5 millimeters (standard version) or
optional reference pulse output (versions 007 and 027) available
Despite the small dimensions the evaluation electronic (translator) is integrated in the sensor head. Optionally, a
vertically mountable LMIX22 variant is available. This must be specified as option “L” with the order ( 12.1).
Please note the following when ordering option “L”:
The position of the internal sensor board is displaced by 90°. So a horizontal mounting, respectively sensing is
no longer possible!
Further information about the mounting positions:
Standard: horizontal installation ( 7.3.2.1)
Option L: vertical installation ( 7.3.2.2)
5.1 Version LMIX22-007
Instead of a periodical index pulse (channels Z / Z‘), a single reference pulse (channels R / R‘) occurs at the
position where the magnet angle MW-007 (accessorial part 12.5) is installed. For more information refer to
sections 7.4 and 8.2.
5.2 Version LMIX22-027
Instead of a periodical index pulse (channels Z / Z‘), a single reference pulse (channels R / R‘) occurs at a desired position of the magnetic tape ( 8.3). In this case, a dual track magnetic tape (type MB20-50-10-2) must
be used. The desired reference pulse position can be ordered by using the type designation of the magnetic
tape ( 12.3). See also example 8.3.

The index pulse output occurs
periodically every 5 mm or optionally as a free definable reference pulse (R / R’).
5.3 Functional Principle
The basis of the magnetic incremental encoders consists of a scanning technology, which scans the north and
south poles on the coded magnetic tape and produces a single Sine/Cosine wave for each pole. The complete
sine/cosine signal process is interpolated electronically. Depending on refinement of the interpolation, together
with the pole distance of the magnetic tape, the resolution of the measuring system is determined.
A special evaluation electronic (translator) processes the sine/cosine wave into square output signals from the
signal information of the magnetic tape. These square signals are equivalent to conventional optical rotary- or
linear encoder outputs.
The translator circuit of the LMIX22 measuring system is already integrated in the sensor head.

7.2.1 The Magnetic Tape MB20-50-10-1(2)-R
In the standard case, the magnetic tape is delivered as described
It is installed by gluing it to the respective mounting surface.
The magnetic tape consists of 2 pre-assembled components (Figure8: Components of the magnetic tape):
A magnetized, flexible plastic tape (Pos. 3), which is connected with a magnetically conductive steel
tape as inference band (Pos. 4) and is supplied with an adhesive tape (Pos. 5).
A magnetized permeable cover tape (Pos. 1), which serves for the mechanical protection of the plastic
tape (not required for the measurement) and is supplied with an adhesive tape (Pos. 2).
Therefore a divergent tape structure and scope of delivery is also possible.
The cover tape is also available separately

Length cover tape = measuring length + sensor length + 50mm (end caps)
NOTE!
When sticking the magnetic tape pay attention to the markings on the tape and the Sensor.
Improper installation does not provide the correct values. A already glued magnetic tape is
destroyed after the removal, and cannot be used again. Note also the direction of counting
of the measuring system
Preferably the magnetic tape should be glued close to an edge or into a groove, which
should be deep enough to embed the magnetic tape and the cover tape.
When unprotected, the cover tape may peel off!
Therefore:
Use tape end caps ( 12.5) or let the cover tape overlap the end of the magnetic tape and
fix it with a screw.

7.2.3 Handling
In order to avoid tension in the tape, it must not be stretched, compressed or twisted.
It should be stored with the magnetized plastic tape to the outside, the minimum bending radius must be noted
here.
Figure10: Handling
7.2.4 Processing Hint for the Gluing of Magnetic Tapes
Surface-Preparation: In order to guarantee optimal adhesion, all anti adhesive contamination (e.g. oil, grease,
dust, separating agents) has to be removed using solvents with residue-free evaporation.
Suitable agents are ketones or alcohols. Typical solvents for cleaning the surface are a 50/50 isopropyl alcohol/water mixture or heptane. Those agents are offered by Loctite and 3M among others as surface cleaners.
When using solvents, always observe the manufacturer instructions! If the surface is copper, brass etc., it should
be sealed to avoid oxidation.
Contact-Pressure: The strength of the adhesion is directly dependent on the contact the adhesive can form with
the surface. Therefore it is important to use as much pressure as possible when gluing the tape, possibly by using aids such as draw rolls. The optimum contact pressure is 4…5 kg/cm2).
Gluing temperature: The optimal gluing temperature is between + 18° C and 30° C. Avoid colder sticking surfaces than + 10°C, because in this case the adhesive becomes too hard and perhaps a sufficient immediate
adhesion is hardly to achieve. After proper sticking, the stability of the connection is ensured also when the temperature is below zero. The final tackiness of a sticking is from experience reached after approximately 72 hours
(at + 21° C). For gluing use only the supplied adhesive tape.
7.2.5 Cutting and Gluing
Before starting the gluing process, both the magnetic and the cover tape have to be cut to the required length

The tape must be glued smoothly on the surface. The measuring accuracy decreases if the tape is not even!
Before gluing the magnetic tape and the cover tape onto the surface, they should be left lying on the mounting
surface for ca. 30 minutes so that the temperature matches. This prevents strain in the tape due to thermal expansion.
Mounting steps:
1. Thoroughly clean surface ( 7.2.4)
2. Let magnetic tape and cover tape adjust their temperature
3. Remove protection foil of adhesive tape on magnetic tape
4. Glue magnetic tape using great pressure
5. Thoroughly clean surface of magnetic tape
6. Remove protection foil of adhesive tape on cover tape
7. Glue cover tape using great pressure
8. Safeguard the ends of the cover tape against peeling off (using end caps see chapter 12.5)

7.4 Installation of the Magnetic Angle MW-007 for Version LMIX22-007
The magnetic angle must be centred to an arbitrary pole change. In order to determine a pole change, the
magnetic tape poles can be made visible by using the provided pole search film “POSU” (accessory 12.3).
Figure 17: Installation of magnetic angle MW-007 for special version LMIX22-007
7.5 Offset
After the installation of the magnetic tape and the measuring system (sensor head), a value is transmit by the
interface. Because this value does not conform to the machine zero point, an offset should to be deposited at
the controller side.
7.6 Activation of the Device
The device starts automatically after operation voltage application.

9 Extended temperature range (option T)
When ordering option T ( 12.1) the LMIX22 sensor is supplied with an extended temperature range which is
particularly suitable for use in rough environmental conditions (e.g. outdoor solar systems). The extended temperature range with option T is -40 … + 80° C (instead of +10 … +70 °C with standard versions).
In the case of the extended version, it must be noted that the magnetic tape is subject to certain restrictions at
these temperatures:
At these temperatures, the adhesive tape cannot be used for fixing the magnetic tape, but only as a
mounting aid. With extremely high temperatures, the adhesive can soften or become brittle at extremely
low temperatures. Thus extremely temperatures will have a negative effect on the adhesion.
The measuring length with option T is limited to maximum 1000 mm.
9.1 Magnetic tape fixation with option T
Due to the above-mentioned restrictions, the magnetic tape must be mechanically fixed in a different manner in
addition to the adhesive tape (depending on the application and space, for example by clamping the two ends,
fixing with cable ties or the like).
9.2 Prefabricated magnetic tape for option T
In the case of larger numbers, the magnetic tape can be prefabricated on request by ELGO. For this purpose, a
mounting hole with a diameter of 5 mm is punched at the beginning and at the end of the magnetic tape. The
total length of the magnetic tape must be extended accordingly (see box below).

Disturbances, Maintenance, Cleaning
- 27 -
CAUTION!
The device, the connection line and the signal cable must not be installed next to sources of interference that emit
strong inductive or capacitive interference or strong electrostatic fields.
External perturbations can be avoided thorough suitable cable routing.
The screen of the signal output cable should only be connected to the following circuit on one side. The screens
should not be grounded on both sides. Signal cables always have to be routed separately from the load power line.
A safety distance of at least 0.5 m has to be kept from inductive and capacitive sources of interference such as contactors, relays, motors, switching power supplies, clocked controllers etc.!
If interferences occur in spite of all the items stated above being observed, please proceed as follows:
1. Installation of RC-circuits via contactor coils of AC-contactors (e.g. 0,1 µF / 100 Ω)
2. Installation of recovery diodes via DC-inductors
3. Installation of RC-circuits via the different motor phases (in the terminal box of the motor)
4. Do not connect protective earth and ground
5. Connect a mains filter ahead of the external power pack
