Features

Easy to Select

The contacts can be used with either standard loads or microloads.

Standard features include 90

°

overtravel, one-side operation, and four-direction mounting.

Easy to Work With

Downsizing of the built-in switch has increased the space to house the wiring.

Steel screws that are attracted by magnetic screwdrivers have been used for the terminal screws inside the Switches.

Resin and elastomer resistance has replaced the insulating paper.

Easy to See (Models with Operation Indicators)

An indicator with a wide field of view has been used.

A 3D structure disperses light !

Whether the indicator is lit can be clearly seen from the side.

More space!

Light-ON when not operating means the 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.

Structure and Nomenclature

Structure

General-purpose Switches: WLCA2-N

Actuator

Roller

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

Set Position Marker Plate

After operation, set the indicator needle on the marker plate so that is in the convex section of the bearing.

Requires maintenance (excessive overtravel)

Proper range

Proper range

Requires maintenance (excessive overtravel)

Cover Setscrew

Phillips screws are used to ensure ease of use.

Cover

Cover Seal

By using a packing seal as the cover seal, an optimum squeeze can be obtained and high sealing properties are assured as well.

*1.

The available conduit screws are Pg 13.5, M20 and 1/2-14 NPT.

WL-N

Head-mounting Screws

Head

You can remove the two screws to mount the switch in any of the four possible orientations.

Shaft Section Seal

An oil seal is fitted on the inlet of the shaft section to maintain a tight seal.

Operational Plunger

You can change the direction of the operational plunger to electrically switch the direction of operation between both sides, left only, or right only.

Built-in Switch

Built-in switch with SPST-NO+NC contact form.

Terminal Screws

Four, M3.5 screws

Conduit Opening *1

The conduit screw is a parallel screw for G1/2 piping, and is used together with an SC connector to maintain a tight seal.

Indicators

Indicator Covers

The indicator covered if outsert molded from diecast aluminum and has outstanding sealing properties.

Indicator Windows

Operation (i.e., light-ON when operating or light-ON when not operating) depends on

LED is 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°.

Li g ht-ON when Operatin g Li g ht-ON when Not Operatin g

LED at top

Indicator

The indicator is an LED. Models with LED indicators have a built-in rectifier stack, so it is not necessary to change the polarity.

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.

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.

*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.

Spatter-prevention Switches: WLCA2-LDS-N

Actuator

Roller, Roller Axis

Using stainless steel prevents spatter from adhering.

Operating Lever

A baking finish is applied to the surface so that any adhering spatter is easily removed.

Roller Lever Setscrew

Stainless steel construction to prevent spatter adherence.

Double nut models are also available.

Screws

Externally visible screws on the head and cover are made of stainless steel to prevent spatter adherence.

Head Cap

Using fluororesin prevents spatter from adhering.

* Spatter means the zinc powder produced 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.

Safety Precautions

Precautions for Safe Use

Be sure to ground. If not, there is the possibility that electrical shock occurs.

Do not touch charged switch terminals while the switch has carry current, otherwise there is the possibility that electrical shock occurs.

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.

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.

Do not drop the switch. Otherwise, there is the possibility that the switch functions may be spoiled.

Do not connect a Single Limit Switch to two power supplies that are different in polarity or type.

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

Where the humidity is very high and condensation may occur.

Where the vibration is too much

Where receiving direct sunshine.

Where receiving salty wind.

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. Otherwise, there is the possibility that the switch functions may be spoiled.

Precautions for Correct Use

Environment

Take special care to use where there is fine powder, mud and/or foreign materials stacking. And check the condition with actual using condition before using. Then use without a performance problem.

This switch is only for indoor use. If it is used in outdoor, it may be cause of switch failure.

Do not keep the Switch in locations with corrosive gas, such as sulfuric gas (H

2

S or SO

2

), ammonium gas (NH

3

), nitric gas (HNO

3

), or chlorine gas (Cl

2

), 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.

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

(SiO

2

) 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.

Installing the Switch

To install the Switch, make a mounting panel, as shown in the following diagram, and tighten screws using the correct torque.

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.

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.

In the case of mounting screw

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 (1.25mm

2

).

Do not supply electric power when wiring.

Otherwise electric shock may result.

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 lump unit, to avoid interference between lump unit and crimp terminals, wire according to right wiring figure.

Attach the lump unit spring to terminal screw certainly otherwise itÅfs possible to be destroyed or shorted.

The ground terminal is only installed on models with ground terminals.

In the case of prewired connecter and direct connecter

Holding the connecter certainly when pulling connecter.

Don’t pull the cable holding it.

How to handle

Changing direction of the head

By removing the screws in the two corners of the head, the head can be set any of four directions. Be sure to change the plunger for internal operations at the same time.

Built-in Switch

Do not remove or replace the built-in switch.

Overtravel Markers

To allow the roller lever type actuator to travel properly, set the roller lever according to the dog or cam stroke so that the arrowhead of the lever is positioned within overtravel markers as shown.

Connectors

Tighten the connector with the appropriate torque to prevent deformation.

Use the OMRON type SC connector series, which is prepared separately, suitable for outer diameter of cable and inner diameter of seal rubber.

Make sure to wrap the connector with the seal tape, except the connector which has O-ring, to keep the sealability.

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 corrosive gases.

Microload Applications

The switch 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.

Minimum operating load: 5 VDC 1 mA, resistive load, P level

Note: The P level indicates the standard malfunction level at a reliability level of 60% (

λ

60).

(JISC5003)

λ

60 = 0.1

×

10

-6 per operation, which indicates an estimated malfunction of 1 out of every 10,000,000 operations at a reliability level of 60%.

Indicator

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.

Please check the load's OFF current before use the indicatorequipped switch.

Others

For long term (over a year) storage, check according to Operating characteristics, Contact resistance and Dielectric strength at least.

And check with using condition.
