Spatter-prevention Models
High-precision Models Available in All Switch Types;
Ideal for Position Control
Excellent Performance on Arc Welding Lines or Sites with
Spattering Cutting Powder
High-precision models achieve a very small movement to operation
(approx. 5°) and a repeat accuracy that is twice that of basic models.
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.
Operation Indicators for Easier Daily
Inspections*
Long-life Models
Confirm operation with a neon lamp or LED for
easier startup confirmations and maintenance.
Mechanical Endurance of 30 Million Operations
* Operation indicators are provided on Indicator-
equipped switches, Spatter-prevention Basic
Switches, and Long-life Basic Switches.
Long-life Models for High-frequency Applications

* 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.

WL/WLM
Selection Guide
With the WL Series, OMRON will combine the switch, Actuator, and wiring method required to build the ideal switch for
your application.
The WL Series consists of four basic types: General-purpose, En-
vironment-resistant, Spatter-prevention, and Long-life Switches.
WLCA2 Switches can be used for the most common applications.

General-purpose Switches: WLCA2
Head-mounting Screws
Actuator
Roller
Head
The roller is made of self-lubricating
sintered stainless steel and boasts
high resistance to wear.
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.
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.)
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.
Roller Lever Setscrew
Operational Plunger *2
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.
Bearing
The bearing smooths the
plunger movement.

Separator
Cover Seal
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.
Conduit Opening *1
Cover
The conduit threads are parallel threads
for G½ tube and offer further increased
sealing properties when used in
conjunction with the SC connector.
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, any one of the three operational directions (both sides, left, or right) can be selected electrically.

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.)

Note: 1. The indicator cover cannot be replaced on the molded terminals. 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 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
Refer to Safety Precautions for All Limit Switches.
Using Switches for Micro Loads
Precautions for Safe Use
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).
• 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.
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%.

• 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.
43
WL/WLM
Built-in Switch
Connectors
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.
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.
Tightening Torque
Wiring
• 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.
• Use 1.25-mm2 lead wires and M4-insulation covered crimp
terminals for wiring.
