Pressure Resistant Rod-Type Position Sensors
LTX for position sensing in hydraulic cylinders
The LTX is a pressure resistant sensor
for precise position sensing in hydraulic
cylinders. Contactless, wear-free, shock
and vibration proof – these are only some
of the features that make Turck LTX linear
position sensors a standard when it comes
to cylinder installation. With the optimum
configuration factory shipped, the magne-
tostrictive linear position sensor is available
with an analog or SSI interface.

The preferred types are available with the
following default settings:

Your benefits
Faster commissioning…
■
…with Autotuning
The Autotuning function enables the
sensor to adapt automatically to the
positioning element and allows straight-
forward, fast and safe commissioning.
■
…with adjustable blind zones
The blind zones can be optimally adjust-
ed onsite to customer requirements us-
ing an optionally available teach adapter
or the sensor can be ordered as a variant.
Optimum configuration factory
shipped…
■
…with connectors compatible with mar-
ket competitors
This enables simple one-to-one replace-
ment without any effort. The LTX sensors
are shipped as standard with a 5-pin M12
connector.
■
…with a wide range of output types
Besides 4…20 mA and SSI outputs,
0…10 V, -10…10 V, 0…5 V, -5…5 V out-
puts are now also optionally available as
standard.
■
…with an infinitely variable measuring
length
Instead of using the conventional 25 mm
increments, the sensor can be ordered
with a measuring range of 25 mm to
7600 mm in 1 mm increments.
Straightforward handling…
■
… by replacing via removable sleeve
The electronics housing together with
the measuring system can be removed
simply by separating the actual sensor
from the pressure tube via two screws.
The cylinder remains hydraulically sealed.
■
… with multi-color diagnostics LED
The LED indicates fault states in addition
to the position signal.
This saves time and costs for any fault
finding.

Instruction manuals
Contactless and wear-free
The magnetostrictive measure-
ment principle works contactless
and wear-free. Important charac-
teristics such as accuracy, linearity,
resistance to shock and vibration
are maintained ingress protection.
Rugged housing easy installation
The compact LTX sensor meets the
IP68 ingress protection category
and is resistant to many chemi-
cals and oils. The rod is made of
high-quality stainless steel and
offers optimal protection – even
against aggressive media.
Flexible process connection
The LTX adapts perfectly to any
application environment. The
sensor is available in different
versions, either with 0…10 VDC or
4…20 mA analog output, or with
an SSI interface. The connection
is established via standard M12
connectors – special connectors
are not required.
Highest accuracy
High-quality components and an
innovative QM system ensure
accurately measured signals and
form the basis for high linearity
and repeatability. With Turck linear
position sensors, even the most
demanding applications can
be solved in an economically and
technically efficient way.
Shock and vibration resistance
The rugged construction ensu-
res high stability in the event of
vibration and mechanical load. A
vibration resistance of 30 g RMS
and a shock resistance of 100 g
RMS prevent interference and
machine downtimes, even under
intense load in mechanically
demanding applications.
Programmable measuring range
The LTX sensor can be easily pro-
grammed. The required measur-
ing range can be adjusted in an
instant. This helps you to reduce
the inventory of different device
types sustainably.
