Features
Many Variations in Standard Limit Switches
A Wide Range of Models
The series includes includes many different actuators that you select
to match the workpiece shape and motion, and a wide range of Switch
variations, such as models with operation indicators for easier
working and maintenance and models with different types of
connectors.
Select from Six Types of Environment Resistance
The series includes Airtight Switches, Hermetic Switches, Heat-
resistant Switches, Low-temperature Switches, Corrosion-proof
switches, and Weather-proof Switches. You can select the model
based on the onsite environment.
Excellent Performance on Arc Welding Lines or Sites with
Spattering Cutting Powder
Ideal for Welding Sites
These Switches use stainless steel or resin to prevent the adhesion
of spatter.
They can be used to reduce problems caused by zinc power
generated during welding.
Mechanical Endurance of 30 Million Operations
Long-life Models for High-frequency Applications
A mechanical durability of 30 million operations minimum is provided.
The head features a double-seal structure with a head cap and oil
seal.
DPDB Operation
The double-pole, double-break structure ensures circuit braking.
Degree of Protection; IP67
Approved Standards to Aid Export Machines
The Switches are certified for EN/IEC, UL, cUL, and CCC making
them ideal for export machines.
Applicable to Either Standard Loads or Microloads
Standard-feature gold-clad contacts provide high reliability.
The use of a high-contact-pressure crossbar structure also increases
reliability.
Easy to Work With
Downsizing of the built-in switch has increased the space to house the
wiring.
The insulating paper that was often in the way when wiring has been
eliminated.
Nickle-plated steel screws are used for the terminal screws.
The screws adhere to magnetized screwdrivers to prevent dropping and
loosing them.
Models with Connectors to Reduce Wiring
A neon lamp or LED indicates the operating status.
The 3D structure of the lamp cover disperses light so you can check
the operating status from the side.

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.
*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.

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.
*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.
Indicators
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
Use the terminal screws on the built-in
switch to connect to the lamp terminals.
A coil spring is used to make contact, so
connecting to the lamp terminals is not
necessary.
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-wired Connector,
Pre-wired Connector, Three-core, and
Four-core Switches cannot be switched to
light-ON when operating (NC wiring).)

Safety Precautions
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.
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.
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%.
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
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.
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.
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.
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.
Installing the Switch
To install the Switch, make a mounting panel, as shown in the
following diagram, and tighten screws using the correct torque.

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 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.
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 (1.25 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.
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.
Attach the lump 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 connecter and direct connecter
Holding the connecter certainly when pulling connecter.
Don’t pull the cable holding it.
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.
Overtravel Markers
All Switches with Roller Lever Actuators except for Switches with
Fork Lever Locks 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 overtravel markers as
shown.
Connectors
Tighten the connector with the appropriate torque to prevent
deformation.
Use the OMRON type SC connector series, which is prepared
separately, suitable for outer diameter of cable and inner diameter
of seal rubber.
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.
Use a contact protection circuit if required.
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.
Please check the load's OFF current before use the indicatorequipped
switch. 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.

Using a WL@-2N Switch Mounted from the Side
If you replace a previous Switch with a WL@-2N-N Switch, a Mounting
Plate (sold separately) is available to maintain mounting compatibility.
If you use the Mounting Plate, the Switch mounting holes and actuator
position will be compatible. (The position of the dog will not need to
be changed.)
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.
Make sure that the actuator does not exceed the OT (overtravel)
range, otherwise the Limit Switch may malfunction. 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
For long term (over a year) storage, check according to Operating
characteristics, Contact resistance and Dielectric strength at least.
And check with using condition.
The durability of the Switch is greatly affected by operating
conditions.
Evaluate the Switch under actual working conditions before
permanent installation and use the Switch within a number of
switching operations that will not adversely affect the Switch’s
performance.

Using the Switches
Item Applicable models and Actuators Details
Changing the Installation Position
of the Actuator
By loosening the Allen-head bolt on
the actuator lever, the position of the
actuator can be set anywhere within
the 360°.
With Indicator-equipped Switches, 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 backwards, it will not contact the
lamp cover.
(This does not apply to Long-life
Switches.)

* Manufacturing of the high-sensitivity, high-precision models has been discontinued and the models have been integrated into the WL Series.
This information is provided as reference for comparison of specifications. Refer to the model replacement table on page 45 and order WL-series
high-sensitivity or high-precision models.
Operation of Fork Lever Locks
A Switch with a Fork Lever Lock 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 inside.
(Set so that operation can be
completed within a 180° level range.)

Limit Switch Connectors
Connectors (SC Series)
Cabtire cables and flexible tubes with various diameters are used to
connect machine tools and controllers with Limit Switches. To ensure
the watertightness of the edges of the conduits, use an SC Connector
that is suitable for the external diameter of cable and model of Limit
Switch.
Ordering Information
Connector for Cabtire Cable
Note: Please use sealing 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.
Simple Connectors (Not Suitable for Locations Subject to Oil or Water)
Note: Simple connector are made of resin. If more sealing capability is required, use one of SC-1M to SC-5M, which have metal casings.
Models marked with an asterisk (*) however, can only be used with resin connectors.
