Electronic
position switch
Programmable electronic position
switches at any time
A highlight is the world's first LSE (Limit Switch
Electronic) electronic position switch. The devices can
compensate for all measurement tolerances with every
application: The need for cumbersome adjustment with
gauges and sliding callipers is completely eliminated.
Each device has a freely programmable operating point
and can be individually adjusted to suit the application
and can be changed as often as required.
The innovative LSE position switches represent a
market premiere, as it is the first time that a single
device for all applications has been launched on the
market, and is also for safety-relevant tasks and
applications. The use of just a single type offers a
wide-range of advantages: There is an enormous reduction
in the complexity and expense in areas such as
logistics, purchase order processing, stockkeeping and
administration associated with bills of materials.
Further convincing advantages: Divergent positions
for the attachment bores or tolerances of brackets and
flaps have no influence on the operating point of the
position switch. After mounting the device, the
operating point is “learned” eliminating any
time-consuming fine adjustment tasks. This saves
precious time and avoids high tooling costs.
Furthermore, every electrician and mechanic around the
globe is in a position to effortlessly adjust the
devices. The devices plainly signal all actions and
include optical indication.
The LSE-Titan® is also certified by TÜV-Rheinland
"Functional-Safety"
(German authorized inspection agency in the Rhineland
region).
The LSE-11 and the LSE-02 may be used in safety-oriented
circuits.

Safe LSE-AI and LSE-AU analog sensors
The LSE-AI (4 – 20 mA) and LSE-AU (0 – 10 V) analog
position switches offering another advancement in this
field. The actual position of a flue gas flap or an
actuator can now be monitored continuously for the first
time. The position data is converted to an analog
current or voltage value and continuously fed to the
automation environment. Even the data of objects with
different sizes or thicknesses such as brake blocks can
now be monitored and processed further.
Simple speed-based control systems for fan motors or
ventilation systems indicate the extent of the air flap
opening (e.g. 25, 50 and 75 percent), thus allowing
savings in energy and materials. The analog position
switches also feature a diagnostics output for
additional data processing. This ensures that a safe
operating state can be monitored and evaluated at any
time. The position switch also has a self-test function.
Outputs Q1 and Q2 are continuously tested for overloads,
short-circuits to 0 V and short-circuits to +Ue.
Like the electromechanical position switches,
LSE-Titan® position switches ensure category 3 or 4 of
the EN 954-1 standard for machine safety when configured
as a redundant system. All devices are thus suitable for
safety applications that are used for the protection of
persons or processes.
Control circuit devices from the RMQ-Titan® range can
be used in combination with the LS-Titan®, the entire
unit at least offering protection to IP66 front and
rear.
The travel resolution and consequently the resolution
of the analog signal is 100 increments. The mechanical
hysteresis is 0.4 mm with the basic units; the
reproducibility is +/- 0.02 mm.
The roller plunger, roller lever, adjustable roller
lever or actuating rod feature additional mechanical
preloading.
The LSE-AI and LSE-AU are also certified to EN 954-1
