LS-Titan Miniature DIN Switches
Understanding LS-Titan Electronic Safety Position Switches
All four LS-Titan LSE switch
bodies are safety-rated
products. The LSE-11 and
LSE-02 switch bodies both
have a freely programmable
operating point and can be
individually adjusted to suit
the application, and can be
changed as often as required.
These devices feature an
LED on the body, providing
simple indication during
programming and operation.
The LSE-AI (4–20 mA) and
LSE-AU (0–10V) analog
position switches take
position data and convert to
an analog current or voltage
value that can then be
continuously fed into an
automation system. These
two switches also feature
a diagnostic output for
additional data processing.

Notes
LSE-11 and LSE-02—individual operating point adjustment.
LSE-11 and LSE-02 can be used in safety circuits.
S1 is connected to 24 Vdc
S2, S3 each switch with a delay of 0.7s

This ensures that a safe
operating state can be
monitored and evaluated at
any time. A self-test function
is also present on these
models. Outputs Q1 and Q2
are continuously tested for
overloads, short circuits to 0V
and short circuits to +U
e
.
Like the electromechanical
position switches, LS-Titan
electronic position switches
meet 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.
