3 For your safety
The product is designed according to state-of-the-art technology. However, residual risks still
exist. Observe the following warnings and safety notices to prevent damage to persons and
property. Turck accepts no liability for damage caused by failure to observe these warning and
safety notices.
3.1 Intended use
The magnetostrictive linear position sensors are used for contactless and wear-free linear posi-
tion measuring. 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 may only be used as described in these instructions. Any other use is not in accord-
ance with the intended use. Turck accepts no liability for any resulting damage.
3.2 General safety instructions
nThe device meets the EMC requirements for industrial areas. When used in residential areas,
take measures to avoid radio interference.
nThe device may only be assembled, installed, operated, parameterized and maintained by
professionally-trained personnel.
nThe device may only be used in accordance with applicable national and international
regulations, standards and laws.
nOnly operate the device within the limits stated in the technical specifications.

4 Product description
The linear position sensors with an analog output are available with a current or voltage out-
put. An M12 connector is available for the connection. All devices feature a rod design with
IP68 protection. The devices have contactless operation, which requires the use of a positioning
element approved by Turck (see section "Technical accessories"). The measuring range is
adjustable.
The devices operate in absolute mode. Voltage failures do not require renewed homing or
recalibration. All position values are determined as absolute values. Homing movements after a
voltage drop are unnecessary.

4.3 Operating principle
The operation of the Turck LTX sensors is based on the magnetostrictive principle. A so-called
“waveguide” is located in the measuring probe of the linear position sensor. If a current signal
generated on the waveguide hits the magnetic field of the positioning element applied from
outside, this produces a mechanical feedback in the waveguide. This feedback is evaluated in
the sensor head and output as position 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 characterist-
ics).

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.

5 Installing
The device can be mounted in a hydraulic cylinder or externally with a mounting bracket.
NOTICE
Incorrect mounting
Risk of damage to the sensor
Secure the device in place using only the hexagon nut on the sensor head
(max. tightening torque: 50Nm).
Do not fasten by turning the sensor head itself.
Ensure that the positioning element is guided centrally over the pressure pipe
along the entire measuring length (deviation < 0.5 mm).

5.1 Mounting the device in a hydraulic cylinder
NOTICE
Incorrect mounting
Risk of damage to the hydraulic cylinder
Observe the instructions of the cylinder manufacturer and the hydraulic cylinder
specifications.
The devices can be mounted directly in a hydraulic cylinder. For this a hole with a recommen-
ded diameter of 13.5 mm must be provided in the cylinder piston rod (depending on the
cylinder design). To fasten the device, an M18×1.5 threaded hole according to ISO 6149-1 is
required in the end cap of the hydraulic cylinder.

V05.00 | 2022/04 17
5.1.1 Mounting the sensor
Loosen the hexagon nut on the sensor and remove from the thread.
Ensure that the pressure seal O-ring is located on the sensor head.
Mount the non-ferrous spacer between the positioning element and base of the piston
rod.
Mount the positioning element. Observe a minimum distance of 51 mm between the
positioning element and sensor head with the piston rod in the retracted position. If the
minimum distance cannot be observed, sink the positioning element in the cylinder
piston.
Recommendation for sensors with probe lengths of ≥ 1500 mm: Use a protective ring,
e.g. made of polymer (see figure below, item 2). The protecting ring prevents mechanical
wear of positioning elements by the pressure pipe when the piston is fully extended.
Fasten the positioning element and spacer with non-ferrous screws.
Remove the protective cap on the hydraulic cylinder (if present). The bore hole in the
cylinder piston rod should have a diameter of at least 13.5 mm.
Insert the sensor pressure pipe into the cylinder piston.
Screw the sensor into the M18×1.5 threaded bore of the hydraulic cylinder using the
thread of the sensor head (max. tightening torque: 50Nm).

5.2 Fastening the device with mounting bracket externally
NOTICE
Magnetization of metal in close proximity with the measuring probe
Inaccurate measurements
Mount the sensor measuring probe at least 7 mm away from ferromagnetic
material.
NOTE
Non-ferrous materials, such as brass, copper, aluminum, demagnetized stainless
steel or plastic do not impair the function of the sensor.
Loosen the hexagon nut on the thread of the sensor head.
Guide the mounting bracket over the pressure pipe up to the sensor head.
If the mounting bracket has an M18×1.5 threaded hole, screw tight the sensor directly.
Fasten the mounting bracket.
Re-fasten the hexagon nut on the sensor head.

5.2.1 Mounting additional mounting brackets (for external mounting)
On devices over 750 mm in length, additional mounting elements (RB-R10) increase protection
against mechanical stresses such as impacts and vibrations. The mounting elements must be
made from non-ferrous material.
When using additional mounting elements, use a ring-type positioning element with slot
as the positioning element.
Fit mounting elements made from ferromagnetic (already magnetized) material at least
7 mm away from both the blind zone and the active measuring range of the sensor.
Sensors with probe lengths of 750…1800 mm: Fit additional mounting elements as
shown in fig. "Mounting positioning elements".
Sensors with probe lengths > 1800 mm: Fit mounting elements at distances of 1200 mm.

20 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
5.2.2 Installing the positioning element (for external mounting)
Observe a distance of 7 mm between the positioning element and ferrous material. If
necessary, use a spacer.
Observe a distance of 7 mm between the end of the measuring probe and ferrous
material.
The positioning element must not touch the sensor along the entire measuring range.
When using ring positioning elements with a slot: Observe ≤ 5 mm distance between the
positioning element and measuring probe (nominal distance: 1.5 mm).
Push the positioning element into the active measuring range of the sensor.
Fasten the positioning element with non-ferrous screws.
