* 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 (SiO

2

). 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.

Structure and Nomenclature

Structure

General-purpose Switches: WLCA2

Head-mounting Screws

Head

The Head used in the roller lever type, adjustable rod lever type, or horizontal plunger type (except for 90

° operation models) 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.

Operational Plunger *2

Bearing

The bearing smooths the plunger movement.

Built-in Switch

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

Terminal Screws

Four, M4 screws

Separator

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

Conduit Opening *1

The conduit threads are parallel threads for G½ tube and offer further increased sealing properties when used in conjunction with the SC connector.

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. For the

WLD2, insert the needle so that it is between the two main wires on the plunger.

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.

Cover

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

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 whether a neon lamp or 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

°.

(Molded terminals cannot be switched in this way.)

Light-ON when Operating Light-ON when Not Operating

LED at top

Indicator

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.

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.

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.

Spatter-prevention Switches: WLCA2-LEAS

Actuator

Roller, Roller Axis

Using stainless steel prevents spatter from adhering.

Operating Lever

Melamine sinter-painted, it is easy to peel off the spatter.

Double Nut

SUS is used for double nut.

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.

Screws

SUS is used, preventing spatter from adhering.

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

Refer to Safety Precautions for All Limit Switches.

Precautions for Safe 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 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.

Precautions for Correct Use

• 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

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 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% (

λ

60

).

The equation,

λ

60

= 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%.

• 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.

Built-in Switch

Do not remove or replace the built-in switch. If the position of the builtin 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.

• 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.

Rotating Lever Set Position (General-purpose or Spatterprevention Switches Only)

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.

Operation Set Position (Long-life Switches Only)

For all Long-life Switching, there is a set position marker slit on the rubber cap of the head. After operation, set the slit on the rubber cap so that the fluorescent color on the shaft section can be seen.

Terminal Plate

By using a short circuit plate, as shown in the following diagram, the

Switch can be fabricated into a single-polarity double-break switch.

When ordering, specify WL Terminal Plate (product code: WL-
