Environment-resistant Switches

Item

Environment-resistant

Type

Model

Application

Environment-resistant construction

Applicable models

Airtight seal

@-55-N

For uses in locations sub-

ject to cutting oil or water

Uses an airtight built-in switch.

Note: Use the SC Connector for the conduit opening.

All models except the low-

temperature and heat-re-

sistant models

Note: Models can be produced

using standard

actuators.

Hermetic seal

(Molded terminals/

Anti-coolant)

@-139-N

Refer to page 29 for information on the environ-

ment-resistant construction of Switches with Her-

metic Seals.

All models except the low-

temperature and heat-re-

sistant models

Note: Models can be produced

using standard

actuators. Only the

WLCA2-N, WLGCA2-N,

or WLG2-N can be

produced for the WL

141-N and WL

@-145-N.

@-140-N

@-141-N

@-145-N

@-RP40-N

@-RP60-N

Low-temperature

@-TC-N

Can be used at a tempera-

ture of –40

°C (operating

temperature range: –40 to

°C), but cannot with-

stand icing.

• Uses a general-purpose built-in switch.

• Epichlorhydrin rubber is used for rubber parts

such as the O-ring, gasket, etc.

All models except airtight

seal, hermetic seal, heat-

resistant, corrosion-proof,

and indicator-equipped

models

Heat-resistant

@-TH-N

Can be used in tempera-

tures of 120

°C (operating

temperature range: 5 to

120

°C).

• Fluorine rubber is used for rubber parts such as

the O-ring, gasket, etc.

All models except airtight

seal, hermetic seal, heat-

resistant, corrosion-proof,

and indicator-equipped, ny-

lon roller (WLCA2-26N-N),

seal roller models, and res-

in rod (WLNJ-2-N) models

Corrosion-proof

@-RP-N

For use in locations sub-

ject to corrosive gases and

chemicals.

• Diecast parts, such as the switch box, are made

of corrosion-proof aluminum.

• Rubber sealing parts are made of fluorine

rubber, which aids in resisting oils and

chemicals.

• Exposed nuts and screws (except the actuator

section) are made of stainless steel.

• Moving and rotary parts such as rollers are

made of sintered stainless steel or stainless

steel.

• The Head, box, and cover are yellow.

All models except fork lever

lock (WLCA32-41 to -44-

N), low-temperature, heat-

resistant, and indicator-

equipped models

Weather-proof

@-P1-N

For use in parking lots and

other outdoor locations.

• Rubber parts are made from epichlorhydrin

rubber, which has a high-tolerance to changes in

temperature.

• Rollers are made of stainless steel to improve

corrosion resistance.

• Exposed nuts and screws are made of stainless

steel.

Only basic (WLCA2-N/

CA12-N/CL-N), and high-

sensitivity overtravel

(WLG2-N/G12-N/GL-N)

models (excluding heat-re-

sistant models).

This does not apply to Low-

temperature or Heat-resis-

tance, or Indicator-

equipped Switches.
