General-purpose Models
These Limit Switches are two-circuit double-break switches housed
in rugged diecast, thus making it an oil-tight, waterproof and dustproof construction (complies with IP67).
In addition to the standard models, microload models are also available.
A wide range of actuators with a range of functions are available;
rotating lever, plunger, flexible rod etc.
The rubber material in the standard models is designed to be resistant to water and most oils.
Nomenclature
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 is
is between the two main wires on the plunger.
Roller
The roller is made of self-lubricating sintered stainless steel and boasts high resistance to wear.
Head-mounting
Screws
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.)

Head
The Head used in the roller lever type, adjustable
rod lever type, or horizontal plunger type (except
the -2N Series) can be mounted in any of the four
directions by removing the screws at the four corners of the Head.
Cover Seal
By using an O-ring as the cover seal, an optimum
squeeze can be obtained and high sealing properties are assured as well.
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.
Cover
Terminal Screws
M4 screws
Insulator
The insulator has outstanding insulation properties and prevents the generation of any gases
which may corrode the internal parts.
Bearing
The bearing smooths the plunger movement.
Built-in Switch
The built-in switch (for all models except the microload models) has an extended mechanical life of 15
million operations or more.
Note:
Conduit Opening (See note 1.)
The conduit threads are parallel threads for G1/2
tube and offer further increased sealing properties
when used in conjunction with the SC connector.
Cover Setscrew
A Phillips screw is used to ensure ease of use.
1. The display for conduit threads has changed from PF1/2 to G1/2, 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 1/2-14NPT are also available.)
2. By changing the orientation of the operational plunger, three operational directions can be selected electrically. (This is only possible with general-purpose roller lever, adjustable roller lever, and adjustable rod lever models. For the overtravel models, only -2N
Series models have this function.)

3. Life expectancy values are calculated at an operating temperature of 5°C to 35°C, and an operating humidity of 40% to 70%. Contact your OMRON sales representative for more detailed information on other operating environments.
4. 10,000,000 operations min. for general, high-sensitivity, and flexible rod overtravel models.
5. 500,000 operations min. for high-precision and outdoor specifications models. All microload models however, are 1,000,000 operations min.
6. Except the flexible rod models.
7. For low temperature models this is --40_C to 40°C (no icing). For heat-resistive models the range is +5°C to 120°C.

Overtravel Models
Overtravel models are Limit Switches which are provided with a
greater OT to facilitate dog setting.
The overtravel models are classified into three types; general-purpose, high-sensitivity, and models which are capable of one-side
90_ operation, the -2N Series.
The -2N Series can also be installed on either side.
Since this model is identical to the standard model in dimensions,
both models are interchangeable.
Like the standard model, it is oil-tight, waterproof, and dustproof
(complies with IP67).
Overtravel Models (1)
Overtravel Models (2)
General-purpose, high
sensitivity models
-2N Series
Head can be mounted in any
of the four directions.
The lever operates on either
side at 80_.
One-side operation is
impossible.
The Head can be mounted in
two directions, forward and
backward.
The lever operates on either
side at 90_.
One side operation is
possible.

Environment-resistant Models
Spatter-prevention Models
These models are most effective in an arc welding line or places where cutting powder is spattered.
Nomenclature
Double Nut Lever
Roller, Roller Axis
Using stainless steel prevents
spatter from adhering.
Allen-head Lever
SUS304 is used for double nut.
Screws
SUS304 is used, preventing spatter
from adhering.
Operating Lever
Melamine sinter-painted, it is easy to
peel off the spatter.
Head Cap
Using Teflon prevents spatter from adhering.
Note: Spatter means the Zn powder produced when welding.
Adhering spatter to the Limit Switch
may cause malfunction of lever or
lamp cover.
Lamp Cover
Heat-resistant resin is used for the
lamp cover.
By using spherical surface for the
display part, it disperses the direction of spatter.
The lack of gap prevents spatter powder from clogging.

Lamp-equipped Models
The operating status of the Switch can be checked using a neon
lamp of LED indictor.
Circuit checks and troubleshooting errors are easy done.
The lamp-equipped models are ideal in locations using a conveyor
belt where items need to be checked, or locations that are difficult to
inspect for faults.

Operation
Indictor window
The built-in switch’s terminal screws are used to connect the lamp
terminal (indicator cover). Since the connection spring (coil spring)
is used for this connection, it will not be necessary to connect to the
lamp terminal. When a ground terminal is provided however, lead
wire method must be used.
WL-LD has a built-in rectifier stack, so it will not be necessary to
change the polarity.
The indicator cover is molded from diecast aluminum and has outstanding sealing properties. Furthermore, regardless of whether
the power is connected or not, the operating status is shown (operating or not operating), and indicators can be switched from
light-ON when operating and light-ON when not operating, by simply rotating the lamp holder by 180_. (Molded terminals do not have
this switching capacity.)

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.

Precautions
Cautions
Built-in Switch
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.
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.
Correct Use
Correct Tightening Torque
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 parallel with the
Switch. In order to meet EN approval ratings, use a 10-A fuse that
corresponds to IEC269, either a gI or gG.
When wiring terminal screws, use M4 round crimp terminals and
tighten screws to the recommended torque. Wiring with broken
wires, or the 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.
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.

Environmental Precautions
When the Switch is used in locations subject to splashes of water or
oil, the material of the seal, which ensures the sealing properties of
the Switch, may undergo changes in shape and quality. This is due
to deterioration (including expansion and contraction), and may result in reduced performance, ineffective return, and ineffective sealing (leading to ineffective contact, insulation, leakage current, and
fire). Confirm the possible effects of the operating environment on
the Switch before use.
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.

Connectors
Rotating Lever Set Position
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 pages NO TAG to NO TAG.) (SC-1M to -5M
and others.)
All rotating lever models, except the fork lever lock, have a set position marker plate. (See page 7.) After operation, set the indicator
needle on the marker plate so that is in the convex section of the
bearing.
Wiring
Terminal Plate
Use 1.25-mm lead wires and M4-insulation covered crimp terminals
for wiring.
By using a short circuit plate, as shown in the following diagram, the
Switch can be fabricated into a single-polarity double-break model.
When ordering specify WL Terminal Plate (product code:
