• Can be used over a wide range, from positioning to
workpiece detection.
• Easy to use because the stroke in the direction of revolution
can be set to an angle from 45° to 90° (varies by model),
and the lever can be set to any angle over 360°.
• High-sensitivity Switches with minimal movement before
activation (example: WLG2) and High-precision Switches
with high repeatability (example: WLGCA2) are available.

* The standard cable length for a pre-wired connector is 0.3 m. Contact your OMRON representative for information on other cable lengths.
Note: The default setting is light-ON when not operating (NO wiring).
Turn the lamp holder by 180° to change the setting to light-ON when operating (NC wiring).
(However, Three-core and Four-core Switches cannot be switched to light-ON when operating (NC wiring).)

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 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.
*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.

Operation indicator Switches
Indicator Covers
Indicator
The indicator covered if outsert molded
from diecast aluminum and has outstanding
sealing properties.
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.
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.
Contact Spring
Light-ON when Operating/Not Operating
Lamp Holder
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).)
Light-ON when Operating
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.

Safety Precautions
• 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 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.
• 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.
• 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.
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.
• 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.
Not Suitable
62
Suitable
• 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.
Front Mounting : Four, 5.2 +0.2
0 dia. holes
or M5 tapped holes

Using Switches for Micro Loads
Contact faults may occur if a Switch for a general-load is used to
switch a micro load circuit. Use switches in the ranges shown in the
diagram below. However, even when using microload models within
the operating range shown here, if inrush current occurs when the
contact is opened or closed, it may increase contact wear and so
decrease durability. Therefore, insert a contact protection circuit
where necessary.
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%.
For the WL01G@, the N level is a reference value at the min.
operating load of 5 VDC and 1 mA resistive load. An estimated
malfunction rate of 1/2,000,000 operations at a reliability level of 60%
is indicated as a reference value.

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.

Basic Switches
• 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 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.
High-sensitivity and High-precision Switches
• Use 1.25-mm2 lead wires and M4-insulation covered crimp
terminals for wiring.

No.
• Holding the connector certainly when pulling connector.
• Don’t pull the cable holding it.
• 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 36, 37).
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 WL-N Basic Models 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. 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.

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.
Incorrect
• 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.

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 Operation 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 Models.)
Changing the Orientation of the Head
By removing the head screws (two or four
screws), mounting in any of four orientations
is possible. Be sure to change the plunger
for internal operations at the same time.
The roller plunger can be set in either of two
positions at 90°.

for a period of twelve months from the date of sale by Omron (or such other period expressed in writing
by Omron). Omron disclaims all other warranties, express or implied.
(b) Limitations. OMRON MAKES NO WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED, ABOUT
NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE

or otherwise of any intellectual property right. (c) Buyer Remedy. Omron’s sole obligation hereunder shall be, at Omron’s election,
to (i) replace (in the form originally shipped with Buyer responsible for labor charges for removal or replacement thereof) the
non-complying Product, (ii) repair the non-complying Product, or (iii) repay or credit Buyer an amount equal to the purchase price
of the non-complying Product; provided that in no event shall Omron be responsible for warranty, repair, indemnity or any other
claims or expenses regarding the Products unless Omron’s analysis confirms that the Products were properly handled, stored,
installed and maintained and not subject to contamination, abuse, misuse or inappropriate modification. Return of any Products by
Buyer must be approved in writing by Omron before shipment. Omron Companies shall not be liable for the suitability or
unsuitability or the results from the use of Products in combination with any electrical or electronic components, circuits, system

See http://www.omron.com/global/ or contact your Omron representative for published information.
Limitation on Liability; Etc.
OMRON COMPANIES SHALL NOT BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES,
LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY WAY CONNECTED WITH THE PRODUCTS,
WHETHER SUCH CLAIM IS BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY.
Further, in no event shall liability of Omron Companies exceed the individual price of the Product on which liability is asserted.
Suitability of Use.
Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the
combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable
third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is
not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system,
or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with
respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY OR IN LARGE

Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence thereof.
Performance Data.
Data presented in Omron Company websites, catalogs and other materials is provided as a guide for the user in determining
suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate it
to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
Change in Specifications.
Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice
to change part numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be
assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at any time to
confirm actual specifications of purchased Product.
