Limit Switches
Introduction
Limit Switches offer high
precision in terms of accuracy
and repeatability. This is
primarily due to the fact that
they make direct contact
with the target. When an
object contacts the limit
switch lever (or plunger)
the lever moves a pre-travel
distance to the operating
point where the contacts are
tripped. Movement of the
lever beyond this point is
called the over-travel.
Limit switches contain the
following major components.
These may be modular or part
of a single-piece switch.

Actuator
This is the part of the switch
that contacts the target.
Typical actuators are levers
and plungers. Several styles
are available, see Sensor
Learning Course, Page V8-T12-4, for more
information.
Switch Body
This part contains the
electrical contact mechanism.
For complete information on
electrical outputs, see Sensor
Learning Course, Page V8-T12-4.
Te rm in al s
The terminals are the point of
connection for the wiring.
These terminals may be on
the body itself, or housed in a
removable receptacle. The
limit switch may also come
equipped with a factory
installed cable or pinconnector.

The E47 Compact Prewired
Limit Switch by Eaton’s
electrical sector is designed
to be a versatile, slim device
for hard to fit applications
where sealing integrity is
required. The rugged die
cast aluminum alloy housing,
cable connection and switch
mechanism are encapsulated
for protection against extreme
temperature (
[
14° to 158°F
moisture, shock and
vibration. This factory wired
(3m) device has NEMA
enclosure ratings of 4, 6
and 13, making it suitable
for applications such as
machine tool, food
processing and packaging.
THIS SENSOR IS NOT A
SAFETY DEVICE AND IS NOT
INTENDED TO BE USED AS A
SAFETY DEVICE. This sensor
is designed only to detect
and read certain data in an
electronic manner and
perform no use apart from
that, specifically no safetyrelated use. This sensor
product does not include
self-checking redundant
circuitry, and the failure of
this sensor product could
cause either an energized
or de-energized output
condition, which could result
in death, serious bodily
injury, or property damage.
Inductive load ratings are tested at a power factor 0.4 min. for AC power and a time constant of 7 ms max. for DC power. Inrush current for
motor load is six times the steady state current.
Eaton’s LS-Titan™ limit
switch line is a complete
offering of safety position
switches designed for
worldwide application.
Economical insulated
plastic or rugged metal
enclosures and modular,
plug-in operating heads
and bodies make LS-Titan a
flexible switching solution.
A highlight of the LS-Titan
switch line is the world’s
first electronic position
switch (LSE models). These
switches feature freely
programmable operating
points that can be set
individually at any time.
Additional LSE models
provide analog outputs
proportional to the
actuator position.
LS-Titan switches are suitable
for use in safety applications
designed to protect persons
or processes.
