To improve heat resistance, silicone rubber is
used for rubber parts and for the built-in
switch.
The operating temperature range is +5°C to
120°C.

To improve low temperature resistance, sili­cone rubber is used.
The operating temperature range is –40°C to
40°C.

Diecast parts such as the switch box are
made of corrosion-proof aluminum. Rubber­sealing parts are made of fluorine rubber and
exposed nuts and screws are made of stain­less steel. These all aid in resisting oil, chem­icals and adverse weather conditions.

--- Rotary shafts are made of unquenched (i.e.,
untreated) stainless steel to improve corro­sion resistance. Exposed nuts and screws
are made of stainless steel and rubber seal­ing parts of silicone rubber. These factors all
combine to create a product which is resistant
to temperature changes and adverse weather
conditions.

■ List of Models

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.

Set Position Marker Plate Roller

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.

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.

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.

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: 1. The display for conduit threads has changed from PF1/2 to G1/

so the thread size and pitch have not changed. (Conduit threads Pg 13.5 and

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.)

Roller Lever Setscrew

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.

Terminal Screws

Insulator

The insulator has outstanding insulation proper­ties and prevents the generation of any gases
which may corrode the internal parts.

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.)

Limit

Switches

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.

Light-emitting diode (LED)

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.)

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.

Operating Lever

Melamine sinter-painted, it is easy to

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.

Hermetic Seal Model

The lead wires are sealed to the Limit Switch with
resin, providing a hermetically sealed construction.

Leads for molding

Exclusive connector

SUS304 is used for double nut.

Screws

SUS304 is used, preventing 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.

The lack of gap prevents spatter pow­der from clogging.

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).

General-purpose, high sensitivity models Side-installation models

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.

General-purpose/High Sensitivity Models

Note: 1. For all models WL@ indicates a standard model and WL01@ indicates a microload model.

2. One-side operation is not possible with the general-purpose and high-sensitivity models.

3. Unless otherwise indicated, a tolerance of ±0.4 mm applies to all dimensions.

Installation

Item Appropriate model/actuator Details

Changing the installation position of
the actuator

By loosening the Allen-head bolt on the
actuator lever, the position of the actua­tor can be set anywhere within the 360°.
With Lamp-equipped Switches, the actu­ator lever comes in contact with the top
of the lamp 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.

Changing the orientation of the Head

By removing the screws in the four cor­ners of the Head, the Head can be set in
any of the four directions. Be sure to
change the plunger for internal opera­tions at the same time. (The operational
plunger does not need to be changed on
overtravel general-purpose and high­sensitivity models.) The roller plunger
can be set in either two positions at 90°.
WLCA2-2N and WL01CA2-2N can only
be set in either the forward or backward
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 operating direc­tions can be selected. In the case of
overtravel models, by loosening the rub­ber holder using either a coin or a flat­blade screwdriver, and changing the di­rection of the internal rubber section,
one of three operating directions can be
selected.

The tightening torque for the screws on
the Head is 0.78 to 0.88 N·m.

Precautions

Refer to the Technical Information for Limit Switches (Cat. No. C121).

■ 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 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 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 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.

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.

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 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.

No. Type Torque

A Head mounting screw 0.78 to 0.88 N·m
B Cover mounting screw 1.18 to 1.37 N·m

(for securing the lever)

D Terminal screw 0.59 to 0.78 N·m
E Connector 1.77 to 2.16 N·m
F Main Unit screws 4.90 to 5.88 N·m

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.

4.90 to 5.88 N·m
