Excellent Performance on Arc Welding Lines or Sites with
Spattering Cutting Powder
High-precision Models Available in All Switch Types;
Ideal for Position Control
Ideal for Welding Sites
High-precision models achieve a very small movement to operation
(approx. 5°) and a repeat accuracy that is twice that of basic models.
Stainless steel and resins that resist adhesion of spatters are used to
prevent troubles caused by zinc powder generated during welding.
Long-life Models
Mechanical Endurance of 30 Million Operations
Long-life Models for High-frequency Applications
Long life has been achieved by increasing the resistance to friction
and creating better sliding properties in the head mechanism. Greater
visibility is provided when setting with a fluorescent display for setting

* Weather Resistance, Cold Resistance, and Heat Resistance
Silicon rubber is used to increase resistance to weather, cold, and heat. Silicon rubber, however, can generate silicon gas. (This can occur at room temperature, but
the amount of silicon gas generated increases at higher temperatures.) Silicon gas will react as a result of arc energy and form silicon oxide (SiO2). If silicon oxide
accumulates on the contacts, contact interference can occur and can interfere with the device. Before using a Switch, test it under actual application conditions
(including the environment and operating frequency) to confirm that no problems will occur in actual.

Actuator
Roller
Head
The Head used in the roller lever type,
adjustable rod lever type, or horizontal
plunger type (except for 90° operation
models) can be mounted in any of the
four directions by removing the screws
at the four corners of the Head.
Shaft Section Seal
By fitting an O-ring to the rotary shaft
and with an appropriate interference
of the screws, high-sealing properties
are maintained.
The roller is made of self-lubricating
sintered stainless steel and boasts
high resistance to wear.
Lever
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.)

Set Position Marker Plate
After operation, set the indicator needle
on the marker plate so that is in the
convex section of the bearing. For the
WLD2, insert the needle so that it is
between the two main wires on the
plunger.

The separator has outstanding insulation
properties and prevents the generation of any
gases which may corrode the internal parts.
Conduit Opening *1
The conduit threads are parallel threads
for G½ tube and offer further increased
sealing properties when used in
conjunction with the SC connector.
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.
Cover
Cover Setscrew
Phillips screws are used
to ensure ease of use.
*1. The display for conduit threads has changed from PF½ to G½, according to revisions of JIS B 0202. This is only a change in the display, so the thread size and
pitch have not changed. (Conduit threads Pg 13.5 and ½-14NPT are also available.)
*2. By changing the orientation of the operational plunger, three operational directions can be selected electrically.
(This is possible only with standard roller lever, adjustable roller lever, and adjustable rod lever models. For the overtravel models, only 90° operation models have
this function.)

Indicators
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. 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 whether a neon lamp or 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°.
(Molded terminals cannot be switched in
this way.)

*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.

Safety Precautions
For details, be sure to read Safety Precautions for All Limit Switches.
Precautions for Safe Use
Precautions for Correct Use
• When a rod or wired-type actuator is used, do not touch the top end
of the actuator. Doing so may result in injury.
(Applicable models)
WLHAL5 and WL01HAL5 Rod Spring Levers and WLNJ-S2 and
WL01NJ-S2 Steel-wire Actuators.
• A short-circuit may cause damage to the Switch, so insert a circuit
breaker fuse, of 1.5 to 2 times the rated current, in series with the
Switch.
• In order to meet EN approval ratings, use a 10-A fuse that
corresponds to IEC60269, either a gI or gG for general-purpose
types and spatter-prevention models only.
• When wiring terminal screws, use M4 round crimp terminals and
tighten screws to the recommended torque. Wiring with bare wires,
or incorrect crimp terminals, or not tightening screws to the
recommended torque can lead to short-circuits, leakage current,
and fire.
• When performing internal wiring there is a chance of short-circuit,
leakage current, or fire, so be sure to protect the inside of the
Switch from splashes of oil or water, corrosive gases, and cutting
powder.
• 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 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.
Operating Environment
• 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
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
killers) or remove the source of silicon gas.

Built-in Switch
Do not remove or replace the built-in switch. If the position of the builtin switch moves, it can cause reduced performance, and if the
insulation sheet moves (separator), the insulation may become
ineffective.
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.

Precautions for All Limit Switches
(Not including Safety Switches)
Note: Refer to the Precautions section for each Switch for specific precautions applicable to each Switch.
Precautions for Safe Use
• If the Switch is to be used as a switch in an emergency stop circuit
or in a safety circuit for preventing accidents resulting in injuries or
deaths, use a Switch with a direct opening mechanism, use the NC
contacts with a forced release mechanism, and set the Switch so
that it will operate in direct opening mode.
For safety, install the Switch using one-way rotational screws or
other similar means to prevent it from easily being removed. Protect
the Switch with an appropriate cover and post a warning sign near
the Switch in order to ensure the safety.
• Do not supply electric power when wiring. Otherwise electric shock
may result.
• Keep the electrical load below the rated value.
• Be sure to evaluate the Switch under actual working conditions
after installation.
• Do not touch the charged switch terminals while the Switch has
carry current, otherwise electric shock may result.
• If the Switch has a ground terminal, be sure to connect the ground
terminal to a ground wire.
• Do not disassemble the Switch while electric power is being supply.
Otherwise electric shock may result.
• The durability of the Switch greatly varies with switching conditions.
Before using the Switch, be sure to test the Switch under actual
conditions. Make sure that the number of switching operations is
within the permissible range.
If a deteriorated Switch is used continuously, insulation failures,
contact weld, contact failures, switch damage, or switch burnout
may result.
• Maintain an appropriate insulation distance between wires
connected to the Switch.
• Some types of load have a great difference between normal current
and inrush current. Make sure that the inrush current is within the
permissible value. The greater the inrush current in the closed
circuit is, the greater the contact abrasion or shift will be.
Consequently, contact weld, contact separation failures, or
insulation failures may result. Furthermore, the Switch may become
broken or damaged.
I
(A)
Mounting
• Do not modify the actuator, otherwise the operating characteristics
and performance of the actuator will change.
• Do not enlarge the mounting holes of the Switch or modify the
Switch. Doing so may result in insulation failures, housing damage,
or physical injuries.
• Be sure to evaluate the Switch under actual working conditions
after installation.
• Do not apply oil, grease, or other lubricants to the moving parts of
the actuator, otherwise the actuator may not operate correctly.
Furthermore, intrusion of oil, grease, or other lubricants inside the
Switch may reduce sliding characteristic or cause failures in the
Switch.
• Mount the Switch and secure it with the specified screws tightened
to the specified torque along with flat washers and springs. The
actuator of a Pushbutton Limit Switch mounted to a panel with
excessive tightening torque may not operate correctly.
• Be sure to wire the Switch so that the conduit opening is free of
metal powder or any other impurities.
• If glue or bonding agent is applied, make sure that it does not
adhere to the movable parts or intrude inside the Switch, otherwise
the Switch may not work correctly or cause contact failure. Some
types of glue or bonding agent may generate a gas that may have
a bad influence on the Switch. Pay the utmost attention when
selecting the glue or locking agent.
• Do not drop or disassemble the Switch, otherwise the Switch will
not be capable of full performance. Furthermore, the Switch may
become broken or burnt.
• Some models allow changes in head directions. When changing
the head of such a model, make sure that the head is free of any
foreign substance. Tighten each screw of the head to the rated
torque.
• Be sure to take measures so that no foreign material, oil, or water
will penetrate into the Switch through the conduit opening. Be sure
to attach a connector suited to the cable thickness and tighten the
connector securely to the rated torque.
• Do not impose shock or vibration on the actuator while it is fully
pressed. Otherwise, the actuator will partially abrade and an
actuation failure may result.
Wiring
i (Inrush current)
• If the wiring method is incorrect, the wires may get caught on
objects or the lead wires may be pulled excessively. Make sure that
the lead wires are sufficiently long and secure them along the wiring
path.

Technical Guide for Limit Switches
Precautions for Correct Use
Note: An inductive load causes a problem especially in DC circuitry. Therefore,
it is essential to know the time constants (L/R) of the load.
Operating force
• The Switch in actual operation may cause accidents that cannot be
foreseen from the design stage. Therefore, the Switch must be
practically tested before actual use.
• When testing the Switch, be sure to apply the actual load condition
together with the actual operating environment.
• All the performance ratings in this catalog are provided under the
following conditions unless otherwise specified.
Inductive load:
A minimum power factor of 0.4 (AC) or a maximum time constant
of 7 ms (DC)
Lamp load:
An inrush current 10 times higher than the normal current
Motor load:
An inrush current 6 times higher than the normal current
(1) Ambient temperature: +5°C to +35°C
(2) Ambient humidity: 40% to 70%RH
• The following graph shows an example of changes in contact force
according to the stroke. The contact force near the OP or RP is
unstable, and the Limit Switch cannot maintain high reliability.
Furthermore, the Limit Switch cannot withstand strong vibration or
shock.

Mechanical Characteristics
Operating Force, Stroke, and Contact Characteristics
• The following graph indicates the relationship between operating
force and stroke or stroke and contact force. In order to operate the
Limit Switch with high reliability, it is necessary to use the Limit
Switch within an appropriate contact force range. If the Limit Switch
is used in a normally closed condition, the dog must be installed so
that the actuator will return to the FP when the actuator is actuated
by the dog. If the Limit Switch is used in a normally open condition,
the actuator must be pressed to 70% to 100% of the OT (i.e., 60%
to 80% of the TT) and any slight fluctuation must be absorbed by
the actuator.
• If the full stroke is set close to the OP or RP, contact instability may
result. If the full stroke is set to the TTP, the actuator or switch may
become damaged due to the inertia of the dog. In that case, adjust
the stroke with the mounting panel or the dog.
Refer to page 11, Dog Design, page 12, Stroke Settings vs. Dog
Movement Distance, and page 12, Dog Surface for details.
http://www.ia.omron.com/
• If the Limit Switch is used so that the actuator is constantly pressed,
it will fail quickly and reset faults may occur. Inspect the Limit Switch
periodically and replace it as required.
Mechanical Conditions for Switch Selection
• The actuator must be selected according to the operating method.
(Refer to page 9.)
• Check the operating speed and switching frequency.
1. If the operating speed is extremely low, the switching of the
movable contact will become unstable, thus resulting in incorrect
contact or contact weld.
2. If the operating speed is extremely high, the Switch may break due
to shock. If the switching frequency is high, the switching of the
contacts cannot catch up with the switching frequency. Make
sure that the switching frequency is within the rated switching
frequency.
• Do not impose excessive force on the actuator, otherwise the
actuator may become damaged or not operate correctly.
• Make sure that the stroke is set within the suitable range specified
for the model, or otherwise the Switch may break.
Electrical Characteristics
Electrical Characteristics for Switch Selection
• The switching load capacity of the Switch greatly varies between
AC and DC. Always be sure to apply the rated load. The control
capacity will drastically drop if it is a DC load. This is because a DC
load has no current zero-cross point, unlike an AC load. Therefore,
if an arc is generated, it may continue comparatively for a long time.
Furthermore, the current direction is always the same, which
results in a contact relocation phenomena whereby the contacts
easily stick to each other and do not separate when the surfaces of
the contacts are uneven.
• If the load is inductive, counter-electromotive voltage will be
generated. The higher the voltage is, the higher the generated
energy will be, which will increase the abrasion of the contacts and
contact relocation phenomena. Be sure to use the Switch within the
rated conditions.
• If the load is a minute voltage or current load, use a dedicated
Switch for minute loads. The reliability of silver-plated contacts,
which are used by standard Switches, will be insufficient if the load
is a minute voltage or current load.

Technical Guide for Limit Switches
Contact Protective Circuit
Apply a contact protective circuit to increase the contact durability,
prevent noise, and suppress the generation of carbide or nitric acid.
Be sure to apply the contact protective circuit correctly, otherwise an
adverse effect may occur.
The following provides typical examples of contact protective circuits.
If the Switch is used in an excessively humid location for switching a
load that easily generates arcs, such as an inductive load, the arcs
may generate NOx, which will change into HNO3 if it reacts with
moisture.
Consequently, the internal metal parts may corrode and the Switch
may fail. Be sure to select the ideal contact preventive circuit from the
following.
Also, load operating times may be delayed somewhat if a contact
protective circuit (a surge killer) is used.

the contacts are OFF. When the contacts are
open, capacity is stored in the capacitor, and
short-circuit current of the capacitor will flow
when the contacts are turned ON, which may
cause contacts to weld.

Power
supply
This circuit effectively suppresses arcs when
the contacts are OFF. When the contacts are
ON again, however, charge current will flow to
the capacitor, which may result in contact weld.
Load
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 on the right. However, even when using micro load 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. The minimum applicable load is the N-level
reference value. This value indicates the malfunction reference level
for the reliability level of 60% (λ60).
The equation, λ60 = 0.5 × 10–6/operations indicates that the estimated
malfunction rate is less than 1/2,000,000 operations with a reliability
level of 60%.

• Application of Switch to a Low-voltage, Low-current Electronic
Circuit.
1. If bouncing or chattering of the contacts results and causes
problems, take the following countermeasures.
(a)Insert an integral circuit.
(b)Suppress the generation of pulse from the contact bouncing
or chattering of the contacts so that it is less than the noise
margin of the load.
2. Conventional silver-plated contacts are not suited to this
application. Use gold-plated contacts, which are ideal for
handling minute voltage or current loads.
3. The contacts of the Switch used for an emergency stop must be
normally closed with a positive opening mechanism.
• In order to protect the Switch from damage due to short-circuits, be
sure to connect a quick-response fuse with a breaking current 1.5
to 2 times larger than the rated current to the Switch in series. When
complying with EN approved ratings, use a 10-A IEC 60269compliant gI or gG fuse.

• Be sure to protect the Switch with a cover if the Switch is in a
location where the Switch may be actuated by mistake or where the
Switch is likely cause an accident.
Incorrect
Correct
(Malfunction prevented)
• If vibration or shock is continuously imposed on the Switch, contact
failure, malfunction, or decrease in service life may be caused by
abrasive powder generated from the internal parts. If excessive
vibration or shock is imposed on the Switch, the contacts may
malfunction or become damaged. Make sure to install the Switch in
locations free of constant vibration or shock.
• Do not use the Switch with silver-plated contacts for long periods if
the switching frequency of the Switch is comparatively low or the
load is minute. Otherwise, sulfuric film will be generated on the
contacts and contact failures may result. Use the Switch with goldplated contacts or use a dedicated Switch for minute loads instead.

Technical Guide for Limit Switches
• Do not use 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.
• If the Switch is used in locations with silicone gas, arc energy may
create silicon dioxide (SiO2) on the contacts and a contact failure
may result. If there is silicone oil, silicone sealant, or wire covered
with silicone close to the Switch, attach a contact protective circuit
to suppress the arcing of the Switch or eliminate the source of
silicone gas generation.
Regular Inspection and Replacement
• If the Switch is normally closed with low switching frequency (e.g.,
once or less than once a day), a reset failure may result due to the
deterioration of the parts of the Switch. Regularly inspect the Switch
and make sure that the Switch is in good working order.
• In addition to the mechanical durability or electrical durability of the
Switch described previously, the durability of the Switch may
decrease due to the deterioration of each part, especially rubber,
resin, and metal. Regularly inspect the Switch and replace any part
that has deteriorated in order to prevent accidents from occurring.
• If the Switch is not turned On or OFF for a long time, oxidation of
the contacts may decrease contact reliability. Faulty continuity may
result in accidents.
• Be sure to mount the Switch securely in a clean location to ensure
ease of inspection and replacement. The Switch with operation
indicator is available, which is ideal if the location is dark or does
not allow easy inspection or replacement.
Difficult to inspect or install
Easy to inspect
Outdoor Use
• If the Limit Switch is used in places with sludge or dust powder
spray, make sure that the mechanical parts are sealed with a
rubber cap.
• The rubber materials exposed to ozone may deteriorate. Check
that the rubber parts are made of environment-resistive materials,
such as chloroprene, silicone, or fluorine rubber.
• Due to capillary attraction, rainwater may enter the Limit Switch
through the lead wires or sheath. Be sure to cover the wire
connections in a terminal box so that they are not directly exposed
to rainwater.
• If the Limit Switch is used outdoors, the steel parts of the Limit
Switch (such as the screws and plunger parts) may corrode.
Models with resistance against climatic conditions have been
added to the series. Consider using outdoor models, such as the
WL-@P1 or D4C-@P.
• "Limit Switch is used outdoors" refers to an environment where the
Limit Switch is exposed directly to rainwater or sunlight (e.g.,
multistory parking facilities) excluding locations with corrosive gas
or salty breezes. A Limit Switch used outdoors may not release due
to icing and may not satisfy specified standards.
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.
The cover must be located in the
direction ensuring ease of
maintenance or inspection.
Incorrect
Correct
Storage of Switch
• When storing the Switch, make sure that the location is free of
corrosive gas, such as H2S, SO2, NH3, HNO3, or Cl2, or dust and
does not have a high temperature or humidity.
• Be sure to inspect the Switch before use if it has been stored for
three months or more.

Weather Resistance, Cold Resistance, and Heat
Resistance
Silicon rubber is used to increase resistance to weather, cold, and
heat. Silicon rubber, however, can generate silicon gas. (This can
occur at room temperature, but the amount of silicon gas generated
increases at higher temperatures.) Silicon gas will react as a result of
arc energy and form silicon oxide (SiO2). If silicon oxide accumulates
on the contacts, contact interference can occur and can interfere with
the device. Before using a Switch, test it under actual application
conditions (including the environment and operating frequency) to
confirm that no problems will occur in actual.

Stroke Settings vs. Dog Movement Distance
Dog Surface
• The following information on stroke settings is based on the
movement distance of the dog instead of the actuator angle.
The following is the optimum stroke of the Limit Switch.
Optimum stroke: PT + {Rated OT × (0.7 to 1.0)}
In terms of angles, the optimum stroke is expressed as θ1 + θ2.
70% to 100% of rated OT
The surface of dog touching the actuator should be 6.3 S in quality
and a hardness of approximately HV450.
For smooth operation of the actuator, apply molybdenum disulfide
grease to the actuator and the dog touching the actuator. This is ideal
for Limit Switches of drip-proof construction and Multiple Limit
Switches.
Maintenance and Repairs
The user of the system must not attempt to perform maintenance and
repairs. Contact the manufacturer of the system concerning
maintenance and repairs.

• The standard material for the switch seal is nitrile rubber (NBR),
which has superior resistance to oil. Depending on the type of oil or
chemicals in the application environment, however, NBR may
deteriorate, e.g., swell or shrink. Confirm performance in advance.
• The correct Switch must be selected for the load to ensure contact
reliability. Refer to precautions for micro loads in individual product
