WL-N
Select the Best Two-circuit Switch for
the Operating Environment and
Application.
• Standard-feature crossbar contacts provide high
contact reliability.
Applicable to either standard loads or microloads.
• Standard features include 90° overtravel, one-
side operation, and four-direction mounting.
• IP67 degree of protection.
• Approved standards: EN/IEC, UL, cUL, and CCC.
Contact your OMRON representative for
information on approved models.
Be sure to read Safety Precautions on page 24 to 26 and
Safety Precautions for All Limit Switches.
Features
Easy to Select
• The contacts can be used with either standard loads or microloads.
• Standard features include 90° overtravel, one-side operation, and
four-direction mounting.
Easy to See (Models with Operation Indicators)
• An indicator with a wide field of view has been used.
Easy to Work With
• Downsizing of the built-in switch has increased the space to house
the wiring.
• Steel screws that are attracted by magnetic screwdrivers have
been used for the terminal screws inside the Switches.
• Resin and elastomer resistance has replaced the insulating paper.

Note: Leakage current from indicator circuit may cause load's malfunction. Please check the load's OFF current before use the indicator-equipped switch.
*1. Light-ON when not operating means the indicator is lit when the actuator is free and is not light when the Switch contacts (NO) close when the
actuator rotates or is pushed down.
*2. The position of the positioning piece is not always the same. If using an L-shaped connector causes problems in application, use a straight connector.

Actuator
Head-mounting Screws
Roller
The roller is made of self-lubricating
sintered stainless steel and boasts high
resistance to wear.
Head
Lever
You can remove the two screws to
mount the switch in any of the four
possible orientations.
The lever forged of anti-corrosive aluminium
alloy features high corrosion resistances
and outstanding ruggedness.
With roller lever, adjustable rod and flexible
rod models, the actuator position can be set
anywhere within 360°. (The lever cannot be
mounted in the opposite direction.)
Shaft Section Seal
An oil seal is fitted on the inlet of the
shaft section to maintain a tight seal.
Roller Lever Setscrew
Operational Plunger
You can change the direction of the
operational plunger to electrically switch
the direction of operation between both
sides, left only, or right only.
Set Position Marker Plate
After operation, set the
indicator needle on the
marker plate so that is in the
convex section of the bearing.
Built-in Switch

Conduit Opening *1
Phillips screws are used to ensure ease of
use.
The conduit screw is a parallel screw
for G1/2 piping, and is used together
with an SC connector to maintain a
tight seal.
Cover
Cover Seal
By using a packing seal as the cover seal, an
optimum squeeze can be obtained and
high sealing properties are assured as well.

Indicators
Indicator Covers
Indicator
The indicator covered if outsert molded
from diecast aluminum and has outstanding
sealing properties.
The indicator is an LED. Models with LED
indicators have a built-in rectifier stack, so it
is not necessary to change the polarity.
Indicator Windows
Operation (i.e., light-ON when operating or
light-ON when not operating) depends on
LED is used.
Contact Spring
The built-in switch's terminal screws are
used to connect the indicator terminal.
Since the connection spring (coil spring) is
used for this connection, it will not be
necessary to connect the indicator terminal.
When a ground terminal is provided
however, a lead wire must be used.
Light-ON when Operating/Not Operating
Indicators can be switched from light-ON
when operating and light-ON when not
operating, by simply rotating the indicator
holder by 180°.

Note: 1. The indicator cover cannot be replaced on the molded terminals. In all cases the indicator does not light when the load is ON.
*1. Light-ON when operating means that the lamp lights when the Limit Switch contacts (NC) release, or when the actuator rotates or is pushed
down.
*2. Light-ON when not operating means the lamp remains lit when the actuator is free, or when the Limit Switch contacts (NO) close when the
actuator rotates or is pushed down.

Spatter-prevention Switches: WLCA2-LDS-N
Actuator
Roller, Roller Axis
Using stainless steel prevents
spatter from adhering.
Screws
Operating Lever
Externally visible screws on the head and
cover are made of stainless steel to prevent
spatter adherence.
A baking finish is applied to the surface
so that any adhering spatter is easily
removed.
Head Cap
Using fluororesin prevents spatter from
adhering.
Roller Lever Setscrew
Stainless steel construction to prevent
spatter adherence.
* Spatter means the zinc powder produced
when welding.
Double nut models are also available.
Adhering spatter to the Limit Switch may
cause malfunction of lever or lamp cover.
The lack of gap prevents spatter
powder from clogging.

Safety Precautions
Precautions for Safe Use
Precautions for Correct Use
Environment
• Take special care to use where there is fine powder, mud and/or
foreign materials stacking. And check the condition with actual
using condition before using. Then use without a performance
problem.
• This switch is only for indoor use. If it is used in outdoor, it may be
cause of switch failure.
• Do not keep the Switch in locations with corrosive gas, such as
sulfuric gas (H2S or SO2), ammonium gas (NH3), nitric gas (HNO3),
or chlorine gas (Cl2), or high temperature and humidity. Otherwise,
contact failure or corrosion damage may result.
• Seal material may deteriorate if a Switch is used outdoor or where
subject to special cutting oils, solvents, or chemicals. Always
appraise performance under actual application conditions and set
suitable maintenance and replacement periods.
• Install Switches where they will not be directly subject to cutting
chips, dust, or dirt. The Actuator and Switch must also be protected
from the accumulation of cutting chips or sludge.
• Be sure to ground. If not, there is the possibility that electrical shock
occurs.
• Do not touch charged switch terminals while the switch has carry
current, otherwise there is the possibility that electrical shock
occurs.
• Do not disassemble the limit switch or touch inside of it under
supplying power, otherwise there is the possibility that electrical
shock occurs.
• Do not touch the wire or rod type actuator in order to prevent injury.
• Connect a fuse which has 1.5 to 2 times higher breaking current
than the switch rated current to the switch in series in order to
prevent the switch from short-circuit damage.
On the occasion when using the switch with GB ratings, use a 10A
fuse that complies IEC60269, either type gG.
• The durability of switch is depends on the operating condition.
Be sure to check the condition with actual using condition before
using, and use with the number of times of operating without a
performance problem.
• Do not drop the switch. Otherwise, there is the possibility that the
switch functions may be spoiled.
Not Suitable
Suitable
• Do not connect a Single Limit Switch to two power supplies that are
different in polarity or type.
• Be sure to keep the load current less than the rated value.
Otherwise, there is the possibility that the switch may be damage
and/or burnout.
• Do not use the Switch by itself in atmospheres containing
flammable or explosive gases. Arcs and heating resulting from
switching may cause fire or explosion.
• Be sure to prevent the foreign materials such like a scrapped cable
intrusion in to the switch when wiring. Otherwise, there is the
possibility of spoiling the normal operation.
• Never wire to the wrong terminals.
• Do not store or use the switch with following place.
• Where the temperature fluctuates greatly
• Constantly subjecting a Switch to vibration or shock can result in
wear, which can lead to contact interference with contacts,
operation failure, reduced durability, and other problems.
Excessive vibration or shock can lead to false contact operation or
damage. Install Switches in locations not subject to shock and
vibration and in orientations that will not produce resonance.
• The Switches have physical contacts. Using them in environments
containing silicon gas will result in the formation of silicon oxide
(SiO2) due to arc energy. If silicon oxide accumulates on the
contacts, contact interference can occur. If silicon oil, silicon filling
agents, silicon cables, or other silicon products are present near
the Switch, suppress arcing with contact protective circuits (surge
killers) or remove the source of silicon gas.
• Where the humidity is very high and condensation may occur.
• Where the vibration is too much
• Where receiving direct sunshine.
• Where receiving salty wind.
• Do not disassemble and/or modify the switch at anytime.
Otherwise, there is the possibility of spoiling the normal operation.
• Do not apply the force such like deformation and/or degeneration
to the switch. Otherwise, there is the possibility that the switch
functions may be spoiled.
Installing the Switch
• To install the Switch, make a mounting panel, as shown in the
following diagram, and tighten screws using the correct torque.

Overtravel Markers
Tightening Torque
• To allow the roller lever type actuator to travel properly, set the
roller lever according to the dog or cam stroke so that the
arrowhead of the lever is positioned within overtravel markers as
shown.
• If screws are too loose they can lead
to an early malfunction of the Switch,
so ensure that all screws are
tightened using the correct torque.
• In particular, when changing the
direction of the Head, make sure that
all screws are tightened again to the
correct torque. Do not allow foreign
objects to fall into the Switch.

• Make sure to wrap the connector with the seal tape, except the
connector which has O-ring, to keep the sealability.
• To conform to CSA, use a CSA certified water tight treated conduit
hub.
• Even when the connector is assembled and set correctly, the end
of the cable and the inside of the Switch may come in contact. This
can lead to malfunction, leakage current, or fire, so be sure to
protect the end of the cable from splashes of oil or water and
corrosive gases.

Microload Applications
• The switch contacts can be used both for standard loads and
microloads, but once a contact has been used to open and close a
load it can no longer be used for lower loads. Doing so will damage
the contact surface and reduce contact reliability.
• If an inrush current or other sudden load occurs during a switch
operation, the switch will begin to degrade severely which can
result in reduced durability.
Wring
In the case of mounting screw
• Use M3.5-nylon insulation covered crimp terminals (round type) for
wiring.
Ex.) V1.25-M3.5(RAP1.25-3.5) (J.S.T. Mfg. Co.,Ltd.)
• Appropriate wire size is AWG16 (1.25mm2).
• Do not supply electric power when wiring.
Otherwise electric shock may result.
• Do not pull out the wires with excessive force.
It may cause of coming off the wire.
Use a contact protection circuit if required.
• Minimum operating load: 5 VDC 1 mA, resistive load, P level
Note: The P level indicates the standard malfunction level at a
reliability level of 60% (λ60).
(JISC5003) λ60 = 0.1 × 10-6 per operation, which indicates an
estimated malfunction of 1 out of every 10,000,000 operations
at a reliability level of 60%.
• Use crimp terminals for wiring.
• In the case of lump unit, to avoid interference
between lump unit and crimp terminals, wire
according to right wiring figure.
Indicator
Attach the lump unit spring to terminal screw
certainly otherwise itÅfs possible to be destroyed
or shorted.
Indicator-equipped switch has contacts and indicator in parallel.
When contacts are open, leakage current flows through the indicator
circuit and may cause load's malfunction.
• The ground terminal is only installed on models
with ground terminals.
Please check the load's OFF current before use the indicatorequipped
switch.
Others
In the case of prewired connecter and direct connecter
• Holding the connecter certainly when pulling connecter.
• Don’t pull the cable holding it.
• For long term (over a year) storage, check according to Operating
characteristics, Contact resistance and Dielectric strength at least.
And check with using condition.
How to handle
Changing direction of the head
• By removing the screws in the two corners of the head, the head
can be set any of four directions. Be sure to change the plunger for
internal operations at the same time.
Built-in Switch
• Do not remove or replace the built-in switch.
