Description

• Can be used over a wide range, from positioning to

workpiece detection.

• Easy to use because the stroke in the direction of revolution

can be set to an angle from 45° to 90° (varies by model),

and the lever can be set to any angle over 360°.

• High-sensitivity Switches with minimal movement before

activation (example: WLG2) and High-precision Switches

with high repeatability (example: WLGCA2) are available.

• The tip of the plunger is made of a steel ball, which can be

operated in any direction with no limitations.

• The ball plunger is convenient when the mounting side is not

aligned with the movement direction of the dog or the Limit

Switch is actuated by two dogs in X and Y directions.

• Operation from any direction over 360° is possible,

excluding the axial direction.

• Lowest activation force of the limit switches. Effective for

detection of non-uniform directions and shapes.

• Large tolerance for workpiece play because the actuator

absorbs movement after activation.

* The standard cable length for a pre-wired connector is 0.3 m. Contact your OMRON representative for information on other cable lengths.

Note: The default setting is light-ON when not operating (NO wiring).

Turn the lamp holder by 180

° to change the setting to light-ON when operating (NC wiring).

(However, Three-core and Four-core Switches cannot be switched to light-ON when operating (NC wiring).)

Note: Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current

is higher than the leakage current. For countermeasures, refer to technical support on your OMRON website.

*1. Light-ON when not operating means the operation indicator is lit when the actuator is free and is not light when the Switch contacts (NO) close

when the actuator rotates or 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.

Indicator Covers

Indicator

The indicator covered if outsert molded

from diecast aluminum and has outstanding

The indicator is either a neon lamp or an

LED. Switches with LED indicators have a

built-in rectifier stack, so there is no

connection polarity.

Indicator Windows

Operating status (i.e., light-ON when

operating or light-ON when not operating)

depends on whether a neon lamp or an

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

Lamp Holder

Indicators can be switched from light-ON

when operating and light-ON when not

operating, by simply rotating the indicator

holder by 180°.

(However, Direct-wired Connector,

Pre-wired Connector, Three-core, and

Four-core Switches cannot be switched to

light-ON when operating (NC wiring).)

Safety Precautions

• 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

suppressor) or remove the source of silicon gas.

Precautions for Safe Use

• Be sure to ground. Otherwise electric shock may result.

• Do not touch charged switch terminals while the switch has carry

current, Otherwise electric shock may result.

• Do not disassemble the limit switch or touch inside of it under

supplying power,

Otherwise electric shock may result.

• Do not disassemble the limit switch or touch inside of it under

supplying power, otherwise there is the possibility that electrical

shock occurs.

• Do not touch the wire or rod type actuator in order to prevent injury.

• Connect a fuse which has 1.5 to 2 times higher breaking current

than the switch rated current to the switch in series in order to

prevent the switch from short-circuit damage.

Installing the Switch

• To install the Switch, make a mounting panel, as shown in the

following diagram, and tighten screws using the appropriate

tightening torque.

• On the occasion when using the switch with GB ratings, use a 10A

fuse that complies IEC60269, either type gG.

• The durability of switch is depends on the operating condition Be

sure to check the condition with actual using condition before

using, and use with the number of times of operating without a

performance problem.

• Otherwise, there is the possibility of spoiling the normal operation.

Do not drop the switch.

• Do not connect a Single Limit Switch to two power supplies that are

different in polarity or type. Risk of interference.

• Be sure to keep the load current less than the rated value.

Otherwise, there is the possibility that the switch may be damage

and/or burnout.

• Do not use the Switch by itself in atmospheres containing

flammable or explosive gases. Arcs and heating resulting from

switching may cause fire or explosion.

• Be sure to prevent the foreign materials such like a scrapped cable

intrusion in to the switch when wiring. Otherwise, there is the

possibility of spoiling the normal operation.

• Never wire to the wrong terminals.

• Do not store or use the switch with following place.

Where the temperature fluctuates greatly

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 microload 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.

For the WL-N, the P level is at the min. operating load of 5 VDC and

1 mA resistive load.

Note: The P level indicates the standard malfunction level at a

reliability level of 60% (λ⁶⁰).

Where the humidity is very high and condensation may occur.

Where the vibration is too much

Where receiving direct sunshine.

(JISC5003) λ⁶⁰=0.1×10^-6/operations indicates that the

estimated malfunction rate is less than 1/10,000,000

operations with a reliability level of 60%.

Where receiving salty wind.

For the WL01G@, the N level is a reference value at the min.

operating load of 5 VDC and 1 mA resistive load. An estimated

malfunction rate of 1/2,000,000 operations at a reliability level of 60%

is indicated as a reference value.

• Do not disassemble and/or modify the switch at anytime.

Otherwise, there is the possibility of spoiling the normal operation.

• Do not apply the force such like deformation and/or degeneration

to the switch.

or chlorine gas (Cl²), or high temperature and humidity.Otherwise,

contact failure or corrosion damage may result.

• 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.

ensure that all screws are tightened

using the appropriate tightening torque.

• In particular, when changing the

direction of the Head, make sure that all

screws are tightened again to the

appropriate tightening torque. Do not

allow foreign objects to fall into the

Switch.

• Holding the connector certainly when pulling connector.

• Don’t pull the cable holding it.

• To conform to CSA, use a CSA certified water tight treated conduit

hub.

• 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

Basic Switches

• Use M3.5-nylon insulation covered crimp terminals (round type) for wiring.

Ex.) V1.25-M3.5(RAP1.25-3.5) (J.S.T. Mfg. Co.,Ltd.)

• Appropriate wire size is AWG16 (1.25 mm²).

• Do not supply electric power when wiring. Otherwise electric shock

may result.

Microload Applications

• The WL-N Basic Models contacts can be used both for standard

loads and microloads, but once a contact has been used to open

and close a load it can no longer be used for lower loads. Doing so

will damage the contact surface and reduce contact reliability.

• If an inrush current or other sudden load occurs during a switch

operation, the switch will begin to degrade severely which can

result in reduced durability. Use a contact protection circuit if

required.

• Do not pull out the wires with excessive force. It may cause of

coming off the wire.

• Use crimp terminals for wiring.

• In the case of indicator unit, to avoid interference

between lump unit and crimp terminals, wire

according to right wiring figure.

Attach the indicator unit spring to terminal screw

certainly, otherwise it's possible to be destroyed or

shorted.

Indicator

• The ground terminal is only installed on models

with ground terminals.

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. Leakage current may cause

load malfunction (i.e., the load may remain ON). Make sure that the

load operating current is higher than the leakage current. For

countermeasures, refer to technical support on your OMRON

website.

High-sensitivity and High-precision Switches

• Use 1.25-mm²lead wires and M4-insulation covered crimp

terminals for wiring.

• Make sure that the actuator does not exceed the OT (overtravel)

range, otherwise the Limit Switch may malfunction. When

mounting the Limit Switch, be sure to adjust the Limit Switch

carefully while considering the whole movement of the actuator.

Operation

• Carefully determine the position and shape of the dog or cam so

that the actuator will not abruptly snap back, thus causing shock.

In order to operate the Limit Switch at a comparatively high speed,

use a dog or cam that keeps the Limit Switch turned ON for a

sufficient time so that the relay or valve will be sufficiently

energized.
