Installation of the Sensor
The sensor is fixated on the cabin or on the car frame. The mounting position is basically determined by the
condition.
The integrated mounting notches on the housing of
the sensor head allow for a very simple and self-
explanatory installation from three sides. You can
either use M6 hexagon head screws (DIN 933) or M6
square nuts (DIN 562), to mount the system at the
desired position.

NOTE
During installation of the magnetic tape in the sensor, pay attention to the marks on the mag-
netic tape and on the sensor head.
Wrong orientation of tape vs. Sensor head will yield incorrect position readings!
The arrows printed on the magnetic tape and sensor head point in positive counting direction
(in the direction of the shaft head)!

Description installation / Mounting 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. per-
manent magnets, magnetic clamps, electromagnets, magnetic stands)! This may cause
irreparable damage, which will compromise the measuring accuracy or even the function-
ing.

General Information
The technology has proven to be highly robust.LIMAX2 will work under the most adverse environmental condi-
tions. Extreme temperatures, high moisture and excessive soiling will not alter the information coded onto the
tape nor will these conditions affect reading precision of the sensor. Even weak magnetic fields such as they are
generated by door magnets can be tolerated.
If some basic rules and guidelines are followed LIMAX2 systems require a minimum amount of installation and
maintenance effort while offering maximum lifetime.
One important issue to consider is the protection of the magnet tape against mechanical wear. The LIMAX2
tape consists of two components:
-
The magnetic tape which actually carries the position information
-
A protective steel tape which gives the mechanical properties
