Features
Many Variations in Standard Limit Switches
A Wide Range of Models
The WL Series provides a complete range of Limit Switches with a
long history of meeting user needs. Select environment-resistant
specifications, actuators for essentially any workpiece, operating
sensitivity matched to the workpiece, operation indicators to aid
operation and maintenance, and various wiring specifications.
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. Select the one required by the
onsite environment.
Excellent Performance on Arc Welding Lines or Sites with
Spattering Cutting Powder
Ideal for Welding Sites
Stainless steel and resins that resist adhesion of spatters are used to
prevent troubles caused by zinc powder generated during welding.
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
the stroke.
DPDB Operation
The double-pole, double-break structure ensures circuit braking.
Degree of Protection; IP67
O-rings, cover seals, and other measures provide a water-proof, drip-
proof structure (IP67).
Approved Standards to Aid Export Machines
Various WL/WLM switches are approved by UL, CSA, TÜV, EN/IEC,
and CCC making them ideal for export machines.
High-precision Models Available in All Switch Types;
Ideal for Position Control
High-precision models achieve a very small movement to operation
(approx. 5°) and a repeat accuracy that is twice that of basic models.
Operation Indicators for Easier Daily
Inspections*
Confirm operation with a neon lamp or LED for
easier startup confirmations and maintenance.
* Operation indicators are provided on Indicator-
equipped switches, Spatter-prevention Basic
Switches, and Long-life Basic Switches.
Models with Connectors to Reduce Wiring
Reduce wiring with one-touch connection. Models with direct-wired
and prewired connectors that make Switch replacement easier are
also available.

* Weather Resistance, Cold Resistance, and Heat Resistance
Silicon rubber is used to increase resistance t o weather, co ld, and heat. Silicon rubber, howe ver , can generat e silicon ga s. (T his ca n occu r at ro om temp erature , but
the amount of silicon gas generated increa se s at hi gher 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 act ual application conditions
(including the environment and operating frequency) to confirm that no problems will occur in actual.

*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. ( Co nduit threads Pg 13.5 and ½-14NPT are also available.)
*2. By changing the orientation of the operati onal plunger, any one of the three operational directions (both sides, left, or right) can be selected electrically.

The bearing smooths the
plunger movement.
The separator has outstanding insulation
properties and prevents the generation of any
gases which may corrode the internal parts.
By using a packing seal as the cover seal,
an optimum squeeze can be obtained and
high sealing properties are assured as well.
The conduit threads are parallel threads
for G½ tube and offer further increased
sealing properties when used in
conjunction with the SC connector.
The roller is made of self-lubricating
sintered stainless steel and boasts
high resistance to wear.
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.)
Built-in switch with SPST-NO+NC
contact form.
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.
By fitting an O-ring to the rotary shaft
and with an appropriate interference
of the screws, high-sealing properties
are maintained.
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.
Phillips screws are used
to ensure ease of use.

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

Light-ON when Operating/Not Operating
The indicator covered if outsert molded
from diecast aluminum and has
outstanding sealing properties.
Operation (i.e., light-ON when operating
or light-ON when not operating) depends
on whether a neon lamp or 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°.
(Molded terminals cannot be switched in
this way.)
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.
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.

from adhering.
* Spatter means the zinc powder
produced when welding.
Adhering spatter to the Limit Switch
may cause malfunction of lever or
lamp cover.
The lack of gap prevents spatter
powder from clogging.
Melamine sinter-painted, it is easy to
peel off the spatter.
· Heat-resistant resin is used for the
lamp cover.
· By using spherical surface for the
display part, it disperses the direction
of spatter.

Actuator
By using a packing seal as the
cover seal, an optimum squeeze
can be obtained and high sealing
properties are assured as well.
The roller is made of self-lubricating stainless
sintered and boasts high resistance to wear.
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.)
The stroke is indicated in fluorescent color that
is visible from the slit in the rubber cap.
The separator has outstanding
insulation properties and prevents
the generation of any gases
which may corrode the internal
parts.
Phillips screws are used to
ensure ease of use.
In addition to level screws which use G½
tube, direct-wired and pre-wired connectors
have been added to the Series.
Built-in switch with SPST-NO+NC
contact form.
The bearing smooths the plunger
movement.
Smooth movement is achieved using
olefin grease. (Standard models use
molybdenum disulfide grease.)
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.
The Head can be mounted in any of the
four directions by removing the screws
at the four corners of the Head.
Hardening method changed for greater
abrasion resistance.

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.

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
•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-purpo se
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.
•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.
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 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%.

Built-in Switch
Do not remove or replace the built-in switch. If the position of the built-
in switch moves, it can cause reduced performance, and if the
insulation sheet moves (separator), the insulation may become
ineffective.
Tightening Torq ue
•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.
Installing the Switch
To install the Switch, make a mounting panel, as shown in the
following diagram, and tighten screws using the correct torque.
Mounting
Mounting
Connectors
Either the easy-to-use Allen-head nut or the SC Connector can be
used as connectors. To ensure high-sealing properties, use the SC
Connector. Refer to Limit Switch Connectors for details on SC
Connectors.
Wiring
•Use 1.25-mm2 lead wires and M4-insulation covered crimp
terminals for wiring.
•The ground terminal is only installed on models with ground
terminals.
Rotating Lever Set Position (General-purpose or Spatter-
prevention Switches Only)
All rotating lever models, except the fork lever lock models, have a set
position marker plate. (See page 23.) After operation, set the indicator
needle on the marker plate so that is in the convex section of the
bearing.
Operation Set Position (Long-life Switches Only)
For all Long-life Switching, there is a set position marker slit on the
rubber cap of the head. After operation, set the slit on the rubber cap
so that the fluorescent color on the shaft section can be seen.
Terminal Plate
By using a short circuit plate, as shown in the following diagram, the
Switch can be fabricated into a single-polarity double-break switch.
When ordering, specify WL Terminal Plate (product code: WL-
9662F).
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 indicator-
equipped switch.

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 actua-
tor 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 (except for long-life models).

Changing the Orientation of the Head
By removing the screws in the four cor-
ners of the Head, the Head can be set
in any of the four directions. Be sure to
change the plunger for internal opera-
tions at the same time. (The operation-
al plunger does not need to be
changed on general-purpose and high-
sensitivity overtravel models.) The roll-
er plunger can be set in either two po-
sitions at 90°.
WLCA2-2N and WL01CA2-2N can be
set only in either the forward or back-
ward direction.

Changing the Operating Direction
By removing the Head on models
which can operate on one-side only,
and then changing the direction of the
operational plunger, one of three oper-
ating directions can be selected. For
overtravel 90° operation models, one
of three operating directions can be se-
lected by loosening the rubber holder
using either a coin or a flat-blade
screwdriver and changing the direction
of the internal rubber section.
The tightening torque for the screws on
the Head is 0.78 to 0.88 N•m.

Cam Direction Changing Procedure for Overtravel, 90° Operation Switches
Relationship of cam to operation as observed from the rear of Switch
The output of the Switch will be
changed, regardless of which
direction the lever is pushed.
The output of the Switch will
only be changed when the lever
is pushed in one direction.
Loosen the cam holder with a
coin or screwdriver. Take out
the cam from the Switch.
Change the direction of the cam as
required by your intended operation
and then reinstall the cam.

Operation of Fork Lever Locks
The fork lever lock is configured so that the dog pushes the lever to reverse the output and this reversed state is maintained even after
the dog continues on. If the dog then pushes the lever from the opposite direction, the lever will return to its origina l position.
