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

* 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.

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.

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.

• 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.

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-mm²lead wires and M4-insulation covered crimp

terminals for wiring.

Installing the Switch

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

following diagram, and tighten screws using the correct torque.

Mounting

All rotating lever models, except the fork lever lock models, have a set

position marker plate. (See page 23.) After operation, set the indicator

needle on the marker plate so that is in the convex section of the

bearing.
