Environment-resistant Models
Airtight, Hermetic Seal, Low-temperature, Heat-resistive, Corrosion-proof, and Weather-
resistant Models
Using the general-purpose model, six types of environment-resistant models can be created to meet a variety of difficult operating conditions. Se-
lect the model most appropriate to your operating environment.
Note: 1.
Consult your OMRON representative for the microload WL01
@
models.
2.
Use the SC Connector for the conduit opening.
3.
The actuator can be created using the standard model.
4.
The actuator can be created using the standard model. For WL-
@
141 and -145, only WLG2, WLCA2, WLGCA2, and WLH2 can be used.

Airtight seal
For use in locations
subject to splashes of
water and anti-coolant
Uses the W-10FB3-55 Airtight Built-in Switch. (See note 2.) All models except the
low-temperature and
heat-resistive models.

Connection lead wires:
Standard 5-m VCT (vi-
nyl cabtire cable) cable
attached. Finished di-
ameter: 11.5 mm, 4-

Connection lead wires:
Standard 5-m VCT ca-
ble, with high flexibility
and good anti-oil prop-
erties attached. Fin-
ished diameter:
11.5 mm, 4-core.
The case cover, cover
box and conduit open-
ing are molded from
epoxy resin. The cover
cannot be removed

Low-temperature
Can be used at a tem-

C (The operating
temperature range is
–40

cannot withstand icing.
Uses the general-purpose built-in switch.
Silicone rubber is used for rubber parts such as the O-ring,
gasket, etc.
All models except air-
tight, hermetic, heat-
resistive, corrosion-
proof, or lamp-
equipped models.

Heat-resistive
Can be used in tem-

(The operating temper-
ature range is 5

Uses a special built-in switch made from heat-resistant res-
in.
Silicone rubber is used for rubber parts such as the O-ring,
gasket etc.
All models except air-
tight, hermetic, low-
temperature, corro-
sion-proof, lamp-
equipped, nylon roller
(WLCA2-26N), seal
roller models, and res-
in rod (WLNJ-2) mod-
els.

Corrosion-proof
For use in locations
subject 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 oil, chemicals and adverse weather conditions.
Exposed nuts and screws (except the actuator section) are
made of stainless steel.
Moving and rotary parts such as rollers are made of sin-
tered stainless steel or stainless steel.
All models except over-
travel model (-2N), fork
lever lock models
(WLCA32-41 to -43),
low-temperature, heat-
resistive, and lamp-
equipped models.

Outdoor specifica-
tions
For use in parking lots
and other such outdoor
locations.
Rubber parts are made from silicone rubber, which has a
high-tolerance to deterioration over time, and changes in
temperature.
Rollers are made of stainless steel to improve corrosion re-
sistance.
Exposed nuts and screws are made of stainless steel.
Only the general-pur-
pose overtravel models
(WLH2/12), the over-
travel high-sensitivity
models (WLG2/12)
and some standard
models (e.g., WLCA2)
can be used. Excluding
heat-resistive models.
