*Light-ON when not operating means the operation indicator is lit when the actuator is free and is not lit when the actuator rotates or is pushed
down and the Switch contacts contact to NO.
The above shows details of the switch interior. External wires (external resistances) are not shown. For details, refer to Operation on page 18.
Note: Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current
is higher than the leakage current.
For countermeasures, refer to technical support on your OMRON website.

Operation Indicator
Indicator Covers
The indicator covered if outsert molded
from diecast aluminum and has outstanding
sealing properties.
Indicator Windows
Operating status (i.e., light-ON when
operating or light-ON when not operating)
depends on whether a neon lamp or an
LED is used.
Indicators can be switched from light-ON
when operating and light-ON when not
operating, by simply rotating the indicator
holder by 180°.
(However, Direct-wire connector,
Pre-wired Connector, Three-core, and
Four-core Switches cannot be switched to
light-ON when operating (NC wiring).)
Light-ON when Operating/Not Operating
Indicator
The indicator is either a neon lamp or an
LED. Switches with LED indicators have a
built-in rectifier stack, so there is no
connection polarity.
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.

Operation
Note: 1. Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating
current is higher than the leakage current. For countermeasures, refer to technical support on your OMRON website.
2. For details on accessories (sold separately), refer to page 79.
*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.
*3. The wiring varies depending on when the loads and indicator lamps are operating.
For contacts that include an internal circuit (indicator circuit), connect a resistor for protection.
To find the resistance value and capacity, calculate using the voltage, current, and power that is actually used.
· Resistance (Ω) = Voltage (V) ÷ Current (I)
· Power (W) = Current (A) × Voltage (V)
· Capacity (W) = Power (W) × Margin (approximately 2×)
Use the values below for reference.
Reference: Example of Protection Resistance
The capacity value is a numerical value that does not account for the margin. Select a resistor with sufficient capacity.
When calculating using the leakage current in this catalog, the display becomes slightly dim.
Use of a current that is at least around twice the leakage current is recommended.

Circuit Configuration/Terminal Connection Diagram
*Light-ON when not operating means the operation indicator is lit when the actuator is free and is not lit when the actuator rotates or is pushed
down, and the Switch contacts contact to NO.
The above shows details of the switch interior. External wires (external resistances) are not shown. For details, refer to Operation on page 18.
Note: Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current
is higher than the leakage current.
For countermeasures, refer to technical support on your OMRON website.

* Light-ON when not operating means the operation indicator is lit when the actuator is free and is not lit when the actuator rotates or is pushed
down, the Switch contacts contact NO.
The above shows details of the switch interior. External wires (external resistances) are not shown. For details, refer to Operation on page 18.
Note: Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current
is higher than the leakage current.
For countermeasures, refer to technical support on your OMRON website.

Long-life Switches
WL-N/WL
A mechanical durability of over 30
Million Operations
• Long life has been achieved by increasing the resistance
to friction and creating better sliding properties in the
head mechanism
•Direct-wire Connector and Pre-wired Connector Models
in the lineup
• Operation indicators (LED) installed in all the Long-life
Switches.
Features
Mechanical structure featuring mechanical durability of more than 30 million
operations (WLMCA2-N)
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Be sure to read Safety Precautions on pages 81 to 86 and
Safety Precautions for All Limit Switches.
Head Cap
The head cap helps prevent the entry of cutting
chips.You can use the protrusion on the cap to
confirm the set position.
PEEK resin is used. It provides superior
resistance to wear. You can change the
mounting direction to use any one of the three
operating directions (both sides, left side, or
right side).
Operating Plunger
High sealing performance is achieved. The seal
also serves as a spacer.
There is no troublesome insulating paper,
making it easy to work with the Switch.
Cover Seal
Built-in Switch
Built-in switch with an
SPST-NO+NC contact form.
Terminal Screws
Four, M3.5 screws.
Conduit Opening
In addition to parallel threads for G½ tubing,
direct-wired and pre-wired connector types are available.
Cover Setscrew
You can remove the two screws to
mount the head in any of the four
possible directions.
A combination Philips-slotted screw is used.
A retainer prevents the screw from falling
from the cover even when the screw is loose.
Actuator
Roller
The roller is made of self-lubricating sintered
stainless steel.
It provides superior resistance to wear.
Lever
The lever is forged from anti-corrosive
aluminum alloy. It provides superior corrosion
resistance and outstanding strength. With a
roller lever actuator, the actuator position can
be set anywhere within 360°. (The lever
cannot be mounted in the opposite direction.)
Cover
Shield Structure
A head cap and oil seal form a double-seal structure.
Excellent durability and reliability are ensured.

Terminal Connection Diagram
* Light-ON when not operating means the operation 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. The above shows details of the switch interior. External wires (external resistances) are not shown.
For details, refer to Operation on pages 18.
Note: Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current
is higher than the leakage current. For countermeasures, refer to technical support on your OMRON website.
Connector Pin Layout Diagram
* 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.

Structure and Nomenclature
WLMCA2-N
Head Cap
The head cap helps prevent the entry of cutting
chips.You can use the protrusion on the cap to
confirm the set position.
PEEK resin is used. It provides superior
resistance to wear. You can change the
mounting direction to use any one of the three
operating directions (both sides, left side, or
right side).
Operating Plunger
High sealing performance is achieved. The seal
also serves as a spacer.
There is no troublesome insulating paper,
making it easy to work with the Switch.
Cover Seal
Built-in Switch
Built-in switch with an
SPST-NO+NC contact form.
Terminal Screws
Four, M3.5 screws.
Conduit Opening
In addition to parallel threads for G½ tubing,
direct-wired and pre-wired connector types are available.
Cover Setscrew
You can remove the two screws to
mount the head in any of the four
possible directions.
A combination Philips-slotted screw is used.
A retainer prevents the screw from falling
from the cover even when the screw is loose.
Actuator
Roller
The roller is made of self-lubricating sintered
stainless steel.
It provides superior resistance to wear.
Lever
The lever is forged from anti-corrosive
aluminum alloy. It provides superior corrosion
resistance and outstanding strength. With a
roller lever actuator, the actuator position can
be set anywhere within 360°. (The lever
cannot be mounted in the opposite direction.)
Cover
Shield Structure
A head cap and oil seal form a double-seal structure.
Excellent durability and reliability are ensured.

Set Position Marker Plate
The set position is easy to view.
The stroke is indicated in fluorescent color that
is visible from the slit in the rubber cap.
In addition to parallel threads for G½ tubing,
direct-wired and pre-wired connector types are
available.
Roller
The roller is made of self-lubricating stainless
sintered and boasts high resistance to wear.
Lever
The lever forged of anti-corrosive aluminium
alloy features high corrosion resistance and
outstanding ruggedness. With roller lever
models, the actuator position can be set
anywhere within 360°. (The lever cannot be
mounted in the opposite direction.)
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.
Separator
The separator has outstanding
insulation properties and prevents
the generation of any gases which
may corrode the internal parts.
Cover Mounting Screw
A combination Phillips-slotted
screws are used to ensure ease
of use.

Head
The Head can be mounted in any of the
four directions by removing the screws
at the four corners of the Head.
Release Plunger
Hardening method changed for greater
abrasion resistance.
Shaft Section Seal
By fitting a double seal consisting of
an oil seal and an X-ring to the
rotary shaft, even greater sealing
properties are achieved.
Smoother Movement
A grease holder is provided on the shaft
to prevent the grease from running out.
Smooth movement is achieved using
olefin grease. (Standard models use
molybdenum disulfide grease.)
Built-in Switch
Built-in switch with SPST-NO+NC
contact form.

Note: 1. Please use sealling tape with SC Connectors. SC-1M to SC-5M, however, are provided with an O-ring (NBR) and therefore sealing tape
is not necessary to ensure a proper seal. The SC-6 and SC-P2 models are made of resin. If higher sealing performance is required, use
one of SC-1M to SC-5M, which have metal connectors.

Safety Precautions
For the Safety Precautions for All Limit Switches, refer to the OMRON website.
Meanings of Warning Signal Text
•Be sure to ground. Otherwise electric shock may result.
• Do not touch charged switch terminals while the switch has carry
current, Otherwise electric shock may result.
• Do not disassemble the limit switch or touch inside of it under
supplying power, Otherwise electric shock may result.
• Do not disassemble or touch the inside while the power is turned
on. Otherwise electric shock may result.
• Do not touch the wire or rod type actuator in order to prevent injury.
Doing so may result in 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 EN/IEC/GB ratings,
use a 10 A 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.
• Otherwise, there is the possibility of spoiling the normal operation.
Do not drop the switch.
• Do not connect a Single Limit Switch to two power supplies that are
different in polarity or type. Risk of interference.
•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.
• Using the Switch in a pressed-in state for an extended period of
time can accelerate part deterioration and also lead to failure to
return to the original position. Check the Switch beforehand, and
perform periodic inspection and replacement.
• Do not store or use the switch with following place.
Where the temperature fluctuates greatly.
Where the humidity is very high and condensation may occur.
Where the vibration is too much.
Where receiving direct sunshine.
Where receiving salty wind.
Where exposed to cutting powder, machining chips, oil, and
chemicals inside the protective doors.
Where exposed to cleansers, thinners, and other solvents
• Do not use or store 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.
• 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.
• If the Switch will not be switched ON or OFF for an extended period of
time, contact reliability may degrade due to oxidation of the contact
points, resulting in inadequate conductivity, which could lead to an
accident.
Operating Environment
•This switch is only for indoor use. If it is used in outdoor, it may be
cause of switch failure.
• 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.
• 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.
•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
suppressor) or remove the source of silicon gas.
Installing the Switch
• To install the Switch, make a mounting panel, as shown in the
following diagram, and tighten screws using the appropriate
tightening torque.

Appropriate Tightening Torque
• If screws are too loose they can lead to
an early malfunction of the Switch, so
ensure that all screws are tightened
using the appropriate tightening
torque.
• In particular, when changing the
direction of the Head, make sure that
all screws are tightened again to the
appropriate tightening torque. Do not
allow foreign objects to fall into the
Switch.
Using Switches for Micro Loads
•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. Use a contact protection circuit if
required.
For the WL-N, the P level is at the min. operating load of 5 VDC and
1 mA resistive load.
Note: The P level indicates the standard malfunction level at a
reliability level of 60% (λ60). (JISC5003) λ60 = 0.1×10-6/
operations indicates that the estimated malfunction rate is less
than 1/10,000,000 operations with a reliability level of 60%.
Wiring
In the case of mounting screw
Basic models
• Use M3.5-nylon insulation covered crimp terminals (round type) for wiring.
Ex.) N1.25-M3.5 (RAP1.25-3.5) (J.S.T. Mfg. Co.,Ltd.)
• Appropriate wire size is AWG16 (1.25 mm2).
• 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.
•Avoid connecting the wires directly to the terminal. Instead, attach
using a crimp terminal.
• In the case of indicator unit, to avoid interference
between lump unit and crimp terminals, wire
according to right wiring figure.
• Attach the indicator unit spring to terminal screw
certainly, otherwise it's possible to be destroyed or
shorted.
• The ground terminal is only installed on models
with ground terminals.
In the case of prewired connector and direct
connector
• Holding the connector certainly when pulling connector.
• Don’t pull the cable holding it.
How to handle
Changing direction of the head
•By removing two head screws or four head screws, mounting in
any of four orientations is possible. 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. Risk of
malfunctioning.
Overtravel Markers
•All Switches with Roller Lever Actuators except for Switches with
Fork Lock Levers and Low-temperature Switches have a set
position marker plate.
• 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 the overtravel markers
(pages 15, 16). This enables usage in the optimum state.

Conduit opening preparation
• The connector must be tightened at a suitable tightening torque
(1.77 to 2.16 N). Tightening with excessive torque could damage
the case.
• Select the connector based on the sealed rubber inner diameter for
matching the cable outer diameter. For details, refer to
Accessories (Sold Separately) - Connector (Conduit size: JIS
B0202G1/2) on page 77.
• When mounting the connector, use seal tape (not needed if the
connector includes an O-ring) on the threaded section of the
connector to ensure sealing performance.
• To ensure compliance of this Switch with the CSA standards, use
of a waterproof connector compliant with the CSA is
recommended.
• Using an inappropriate connector or assembling Switches
incorrectly (assembly, tightening torque) can result in malfunction,
leakage current, or fire, so be sure to read the connector instruction
manual thoroughly beforehand.
•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.
• The following wiring is recommended for preventing the entry of
fluids from the conduit opening.
Microload Applications
• The WL-N basic model, WL high-sensitivity model, and high-
precision model 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. Use a contact protection circuit if
required.
Operaition indicator
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. Leakage current may cause
load malfunction (i.e., the load may remain ON). Make sure that the
load operating current is higher than the leakage current. For
countermeasures, refer to technical support on your OMRON
website.
Terminal Plate
By using the Terminal Plate (sold separately), as shown in the
following diagram, the Switch can be used as a single-polarity double-
break switch.

Operation Procedures
Operation
• Carefully determine the position and shape of the dog or cam so
that the actuator will not abruptly snap back, thus causing shock.
In order to operate the Limit Switch at a comparatively high speed,
use a dog or cam that keeps the Limit Switch turned ON for a
sufficient time so that the relay or valve will be sufficiently
energized.
• The method of operation, the shape of the cam or dog, the
operating frequency, and the travel after operation have a large
influence on the durability and operating accuracy of the Limit
Switch. The cam or dog must be smooth in shape.
• Appropriate force must be imposed on the actuator by the cam or
dog in both rotary operation and linear operation. If the dog
touches the lever as shown below, the operating position will not
be stable.
• Unbalanced force must not be imposed on the actuator. Otherwise,
wear and tear on the actuator may result.
• With a roller actuator, the dog must touch the actuator at a right
angle. The actuator or shaft may deform or break if the dog touches
the actuator (roller) at an oblique angle.
•M
ount so that the actuator travel after operation (OT) is not
exceeded. If the travel after operation (OT) exceeds the limit,
switch failure could result. When mounting the Limit Switch, be
sure to adjust the Limit Switch carefully while considering the
whole movement of the actuator.
• The Limit Switch may soon malfunction if the OT is excessive.
Therefore, adjustments and careful consideration of the position of
the Limit Switch and the expected OT of the operating body are
necessary when mounting the Limit Switch.
• When using a pin-plunger actuator, make sure that the stroke of
the actuator and the movement of the dog are located along a
single straight line.
Others
• If the Switch will be left in a location outside the storage
environment conditions, if condensation has formed, or after long-
term storage exceeding one year, at the minimum, check the
operating characteristics, contact resistance, insulation resistance,
and dielectric strength, and conduct a check under the operating
conditions.
• If using normal open (NO), be sure to fully press in the actuator. The
proper press-in depth is about 60% to 80% of the entire motion (TT).
• Conduct periodic inspection on a regular schedule.

Using the Switches
Item Applicable models and Actuators Details
Changing the Installation Position of the
Actuator
By loosening the Allen-head bolt on the ac-
tuator lever, the position of the actuator can
be set anywhere within the 360°.
With Operation Indicator-equipped Switch-
es, the actuator lever comes in contact with
the top of the indicator cover, so use caution
when rotating and setting the lever. When
the lever only moves forwards and back-
wards, it will not contact the lamp cover.
(This does not apply to Long-life Models.)

Operation of Fork Lock Levers
A Switch with a Fork Lock Lever is constructed so that the dog pushes the lever to invert the output and this inverted state is maintained even after
the dog moves on. If the dog then pushes the lever from the opposite direction, the lever will return to its original position.
Installing the Roller on the Inside
By installing the roller lever in the opposite
direction, the roller can be installed on the in-
side. (Set so that operation can be complet-
ed within a 180° level range.)
