5Product Features
The EMIX23 is an incremental magnetic length measuring system. The sensor technology and translator are
placed in the same housing. The magnetic tape is adhered to a flat base with the supplied adhesive tape. The
EMIX23 can be installed up to a maximum distance of 0.8 mm.
The measuring system offers decisive advantages:
Direct and contactless measurement
Distance range between sensor and tape: 0.1... 0.8 mm
Status LED for reading distance available (option only for version 5 VDC / 5 V-TTL)
Theoretically unlimited measurement length
High resolution of 0.001 mm
Repeat accuracy +/- 0.004 mm
Very robust against dust and dirt
Definable reference pulse (option)
Signal output with channels A, A´, B, B´, Z, Z´.
5.1 Functional principle
The basis of the magnetic incremental encoder 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 the interpolation refine-
ment, together with the pole distance of the magnetic tape, the resolution of the measuring system is deter-
mined. The MB 20.20 magnetic tape has a pole pitch of 2 mm. A special evaluation electronic (translator) pro-
cesses 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.

7Installation and First Start-Up
CAUTION
Please read the operating manual carefully before using the device! Strictly observe the Installation instructions!
In case of damage caused by failure to observe this operating manual, the warranty expires.
ELGO is not liable for any secondary damage and for damage to persons, property or assets.
The operator is obliged to take appropriate safety measures.
The first start-up may only be performed by staff that has been trained and authorized by the operator.
7.1 Operating Area
WARNING!
Do not use the device in explosive or corrosive environments!
The device must not be installed close to sources of strong inductive or capacitive interference or strong electrostatic
fields!
CAUTION!
The electrical connections must be made by suitably qualified personnel in accordance with local regulations.
The device may be designed for switchboard mounting. During work on the switchboard, all components must be de-
energized if there is a danger of touching the energized parts!
(protection against contacts)
Wiring works may only be performed in the de-energized state!
Thin cable strands have to be equipped with end sleeves!
Before switching on the device, connections and plug connectors have to be checked!
The device must be mounted in a way that it is protected against harmful environmental influences such as splashing
water, solvents, vibration, shock and severe pollution and the operating temperature must not be exceeded.

Installation and First Start-Up

7.2 Installation of the Magnetic Tape
NOTE: External Magnetic Fields
The magnetic tape must not be influenced by external magnetic fields!
The magnetic tape must not come into direct contact with other magnetic fields (e.g. perma-
nent magnets, magnetic clamps, electromagnets, magnetic stands)! This may cause irrepara-
ble damage, which will compromise the measuring accuracy or even the functioning.
7.2.1 The Magnetic Tape MB20-20-10
In the standard case, the magnetic tape is delivered as described.
It is installed by gluing it to the respective mounting surface.
IMPORTANT NOTE:
EMIX23 with a resolution of ≤1 µm (e.g. 0.001 mm) require single pole magnetized
magnetic tapes with the addition "EPS" (see type designation 10.2). Otherwise the
required accuracy cannot be guaranteed.
For resolutions >1 µm (e.g. 0.005 mm) the conventional magnetic tape can be used
without the addition "EPS".
The magnetic tape consists of 2 pre-assembled components (see Figure 6):
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). The cover tape
is not necessary for the measurement.
Therefore a divergent tape structure and scope of delivery is also possible.
The cover tape is also available separately.

Figure 7: Magnetic Tape with Option BK80
The cover tape (C) is not included in the delivery of this version.
7.2.3 Handling
In order to avoid tension in the tape, it must not be stretched, compressed or twisted and should be stored with
the magnetized plastic tape to the outside. The minimum bending radius is 150 mm.
Figure 8: 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 us-
ing 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 sur-
faces 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 tem-
perature 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
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. 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 (11) or let the cover tape overlap* the end of the magnetic tape and fix
it with a screw.
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 approximately 30 minutes so that the temperature matches. This prevents strain in the tape due to
thermal expansion.
Mounting steps:
Thoroughly clean surface (7.2.4)
Let magnetic tape and cover tape adjust their temperature
Remove protection foil of adhesive tape on magnetic tape
Glue magnetic tape using great pressure
Thoroughly clean surface of magnetic tape
Remove protection foil of adhesive tape on cover tape
Glue cover tape using great pressure
Safeguard the ends of the cover tape against peeling off (using end caps see chapter 9.2)

7.3.2 LED for Distance Monitoring (Option E)
EMIX23 encoders which are equipped with an LED are able to indicate the correct or incorrect reading distance
between sensor and magnetic tape.
LED lights green: Reading distance is ok
LED lights red: Reading distance is not ok
Please note!
This option is (currently) only available for the version with 5 VDC supply / 5 V-TTL levels.

7.3.4 How to install the Sensor and the Magnetic Tape
The location of the reference pulse can be detected by using the magnetic magnifying glass which is included in
the delivery. Please ensure that the mounting is centrally aligned with the magnetic tape center, because the
sensor is wider than the magnetic tape. When ordering, the reference pulse position is starting from the right
side of the magnetic tape.
