4.4 Technical Data Magnetic Tape
With a PMIX system, the magnetic tape is already integrated in the guide cylinder and thus must not be installed.
The magnetic tape consists of two components:

The actual magnetic tape which carries the position information

A mechanical stainless steel back iron

Magnetic tapes for PMIX
Used type of magnetic tape with LMIX sensor: MB20-50-10-1-R
with EMIX sensor: MB20-20-10-1-R
with IZ indicator: MB 20-25-10-1-R
Coding Incremental, single track system
Pole pitch with LMIX sensor: 5 mm
with EMIX sensor: 2 mm
with IZ indicator: 2.5 mm
Operating temperature -20 °C … +65 °C
Relative humidity max. 95 %, non-condensing
Accuracy at 20° C in mm with LMIX sensor: ± (25 µm + 20 µm x L)
with EMIX sensor: ± (20 µm + 20 µm x L)
with IZ indicator: ± (25 µm + 20 µm x L)
L = measuring length in meters
Material carrier tape Precision strip 1.4310 / X10CrNi 18-8 (EN 10088-3)

Influence of external magnets External magnetic fields must not exceed 64 mT (640 Oe; 52 kA/m) on
the surface of the magnetic tape because this could damage or destroy
the code on the tape.
Protection class IP65
4.4.1 Resistance against Chemical Influence
In contact with various substances behaves the magnetic tape (integrated in the guide cylinder) as follows:
Table 4: Resistance against Chemical Influence
Show no or little effect in constant contact after 2-5 years:
formic acid glycerol 93°C linseed oil soy beans oil
cotton seed oil N-hexane lactic acid
formaldehyde 40% Iso octane petroleum

acetone gasoline acetic acid 30% oleic acid
acetylene steam acetic acid, pure acetic acid sea water
ammonia acetic acid 20% isopropyl ether stearic acid 70°C, anhydrous
kerosene
Have strong effects when contacting permanently after 1-5 months:
benzene nitric acid 70% turpentine toluene
lacquer solvent nitric acid, red, vitriolic carbon tetrachloride tetrahydrofuran
trichloroethylene nitrobenzene hydrochloric acid 37%, 93°C xylene
