LS-Titan Miniature DIN Switches

Product Description

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.

Features

●Modular, plug-in

system (head and

body components)

●Positive opening NC

contacts for safety

applications

●Wide variety of economical

plastic and rugged metal

versions available

●Operating heads can

be rotated 90 degrees

to suit speciﬁc direction

of operation

●Unique electronic safety

position switches (LSE

models) provide analog

(0–10 Vdc or 4–20 mA)

outputs proportional to the

actuator position and allow

for easy conﬁguration of

a custom trip point

●Can be ordered as

separate components

(head and body) or as

completely assembled

switches

●Screw and Cage Clamp

(standard on LSE models

and optionally available

on mechanical models)

connections provide larger

wiring areas for easier

installation

●Approved for worldwide

application

Standards and Certiﬁcations

●Safety function by positive

opening contacts per

IEC/EN 60947-5-1 up to

Category 4 per EN 954-1

●TÜV-Rheinland Certiﬁed

for Functional-Safety

(LSE models)

●CSA certiﬁed

●UL listed

●CE

●CCC

Note: Cage Clamp is a

registered trademark of

Wago Kontakttechnik,

32423 Minden, Germany.

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.

LSE-11 and LSE-02—individual operating point adjustment.

LSE-11 and LSE-02 can be used in safety circuits.

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 +Ue.

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.

LS-Titan Safety Interlock Switches

Product Description

Eaton’s LS-Titan™ safety

interlock switches have been

specifically designed for

monitoring the position of

protective guards, such as

doors, flaps, hoods and

grilles. All switches in this

family are safety-rated,

include positively opening

NC contacts, and cannot be

defeated using simple tools,

such as pliers, screwdrivers

and nails.

The LS-Titan safety interlock

family is comprised of three

types of safety switches: key

interlock, door-flap and door-

hinge switches.

Key interlock switches are a

two-piece design, made up of

the switch and key (actuator).

The key portion of the switch

is affixed to a movable door,

cover or other such guard.

The switch itself is mounted

to a rigid portion of the

machine. When the guard is

opened, the key is removed

from the switch, thereby

positively breaking the NC

contacts. This interrupts the

control circuit, stopping

machine operation.

The door-flap and door-hinge

switches are one-piece

designs, suitable for when a

key cannot be mounted in the

application. When an attempt

is made to open a protected

door hinge or flap during

operation, these switches

disconnect the power supply

to the machine or installation.

Both switches feature four-

way adjustable heads.

All LS-Titan safety interlock

switches are approved to

protect personnel and

processes.

Features

●Broad family of safety

interlock switches in

industry-standard

enclosure sizes: miniature

DIN; full-size DIN; and

larger, solenoid key

interlocks providing the

highest degree of

personnel and process

protection

●Large selection of

actuators (keys), including

those for sliding doors,

swing doors and doors that

do not close precisely

●Miniature DIN models have

a ﬁve-way adjustable head,

while full-size DIN models

have four-way adjustable

heads

●Fully safety-rated as

interlocking devices per

EN 1088, with safety

function by positive

opening contacts per

IEC/EN 60947-5-1

●Door-ﬂap and door-hinge

safety switches provide a

unique solution when

actuators (keys) cannot

be used

●IP65 degree of protection

Standards and Certiﬁcations

●UL® listed

●CSA® approved

●CCC

●Positive opening NC

contacts per

EN 60947-5-1

Safety Notes

Do not use as a mechanical

stop/shipping brace.

Any change to an original

Eaton safety position

switch is not permitted and

automatically leads to the

loss of all approvals.

Switch must never

be used as a

mechanical stop.
