3 For your Safety
The product is designed in accordance with the latest standards. However, residual risks still
exist. Observe the following warnings and safety information to prevent personal injury or
damage to property. Turck accepts no liability for damage caused by failure to observe these
warning and safety instructions.
3.1 Intended use
The devices are intended solely for use in industrial areas.
The magnetostrictive linear position sensors are used for contactless and wear-free linear posi-
tion detection. The devices are suitable for use in hydraulic cylinders. By adding float magnets
(available as an option), the devices can also be used for level measurement. The measuring
range is adjustable.
The devices must be used only as described in these instructions. Any other use is not in accor-
dance with the intended use. Turck accepts no liability for any resulting damage.
3.2 General safety information
■The devices are not safety components and must not be used for personal or property
protection.
■The device must be mounted, installed, operated, parameterized and maintained only by
trained and qualified personnel.
■The device complies exclusively with the EMC requirements for industrial applications and is
not suitable for use in residential areas.

Product Description
4 Product Description
The linear position sensors with an analog output are available with a current or voltage output.
An M12 connector is available for the connection. All devices feature a rod design with IP68
protection. The devices operate without contact, which requires the use of a positioning ele-
ment approved by Turck (see Accessories). The measuring range is adjustable.
The devices operate on an absolute basis; power outages do not necessitate renewed zero off-
set adjustment or recalibration. All position values are determined as absolute values; reference
runs after a voltage drop are unnecessary.

4.3 Operating principle
Turck LTX sensors utilize the magnetostrictive principle. A "waveguide" is located in the measur-
ing probe of the linear position sensor. If a current signal generated at the waveguide encoun-
ters the externally applied magnetic field of the positioning element, mechanical feedback is
produced in the waveguide. This feedback is evaluated in the sensor head and output as posi-
tion information.
4.4 Functions and operating modes
The devices feature a current or voltage output. The device output provides a current or voltage
signal proportional to the position of the positioning element (see output characteristics).

4.4.1 Automatic signal control
The device is automatically adjusted to the signal strength of the positioning element as soon
as the sensor is supplied with power. The automatic signal control fully compensates for any
tolerances.
4.4.2 Current output
LTX…LI… devices feature a current output, which outputs a current signal in line with the posi-
tion of the positioning element (e.g. 4…20 mA, depending on design). The measuring range is
adjustable.
4.4.3 Voltage output
LTX…LU… devices feature a voltage output, which outputs a voltage signal in line with the
position of the positioning element (e.g. 0…10V, depending on design). The measuring range
is adjustable.
4.4.4 Preferred types LTX…M-F10-LI0-X3-H1151 – Measuring range
Preferred types LTX…M-F10-LI0-X3-H1151 are available with the following measuring lengths
as standard:
Measuring range congured
100…500mm in 25mm increments
500…2000mm in 50mm increments
2000…7600mm in 500mm increments
