Environment-resistant Switches
Item Environment-resistant
Type Model Application Environment-resistant construction Applicable models
Airtight seal WL@-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)
WL @ -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.

Low-temperature WL@-TC-N
Can be used at a tempera-
ture of –40°C (operating
temperature range: –40 to
40°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 WL@-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 WL@-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 WL@-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.
