General-purpose Models
These LimitSwitches are two-circuitdouble-break switches housed
in rugged diecast, thus making it an oil-tight, waterproof and dust-
proof construction (complies with IP67).
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 resist-
ant to water and most oils.
In addition to the standard models, microload models are also avail-
able.
Nomenclature
Set Pos ition 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 rolleris made ofself-lubricating sintered stain-
less steel and boasts high resistance to wear.
Head -mounting
Screws
Lever
The lever forged of anti-corrosive aluminium alloy
features high corrosion resistances and outstand-
ing 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 cor-
ners of the Head.
Cover Seal
By using an O-ring as the cover seal, an optimum
squeeze can be obtained and high sealing proper-
ties are assured as well.
Terminal Screws
M4 screws
Shaft Section Seal
By fitting an O-ring to the rotary shaft and with an
appropriate interference of the screws, high-seal-
ing properties are maintained.
Cover
Ins ulator
The insulator has outstanding insulation proper-
ties and prevents the generation of any gases
which may corrode the internal parts.
Bearing
The bearing smooths the plunger movement.
Built-in Switch
Cover Sets crew
The built-in switch (for all models except the micro-
load models) has an extended mechanical life of 15
million operations or more.
A Phillips screw is used to ensure ease of use.
Conduit Opening (See note 1.)
The conduit threads are parallel threads for G /
tube and offer further increased sealing properties
when used in conjunction with the SC connector.

Note: 1. The display for conduit threads has changed from PF / to G / according to revisions of JIS B 0202. This is only a change in the

2. By changing the orientation of the operational plunger, three operational directions can be selected electrically. (This is only pos-
sible with general-purpose roller lever, adjustable roller lever, and adjustable rod lever models. For the overtravel models, only -2N
Series models have this function.)

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-pur-
pose, 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).

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
Allen-head Lever
Roller, Roller Axis
Using stainless steel prevents
spatter from adhering.
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 pro-
duced 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 direc-
tion of spatter.
The lack of gap prevents spatter pow-
der from clogging.

Lamp-equipped Models
The operating status of the Switch can be checked using a neon
lamp of LED indictor.
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.
Circuit checks and troubleshooting errors are easy done.

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.
Light-ON when Not Operating
LED at bottom
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 out-
standing sealing properties. Furthermore, regardless of whether
the power is connected or not, the operating status is shown (oper-
ating or not operating), and indicators can be switched from
light-ON when operating and light-ON when not operating, by sim-
ply rotating the lamp holder by 180_. (Molded terminals do not have
this switching capacity.)

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 in-
effective.
Correct Us e
Correct 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.
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.
No.
Type
Torque
0.78 to 0.88 N S m
1.18 to 1.37 N S m
4.90 to 5.88 N S m
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 cur-
rent, and fire.

Using an inappropriate connector or assembling Switches incor-
rectly (assembly, tightening torque) can result in malfunction, leak-
age current, or fire, so be sure to read the instruction manual thor-
oughly beforehand.
Main Unit screws
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, orfire, so be sure to protect the
end of the cable from splashes of oil or water and corrosive gases.
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 re-
sult in reduced performance, ineffective return, and ineffective seal-
ing (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 al-
low foreign objects to fall into the Switch.
Ins talling the Switch
To installthe Switch, make a mounting panel, as shown in the follow-
ing diagram, and tighten screws using the correct torque.

Connectors
Rotating Lever Set Pos ition
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 posi-
tion 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:
