Environment-resistant Limit Switches
WL-N/WLG
Wide range of available models to
match your onsite environment
• Variety of head shapes, including Roller Lever, Plunger,
and Flexible Rod Switches
• Select the optimum actuator model for the ambient operating
temperature and operating environment for use in a wide
range of applications
• Wiring specifications are available in Direct-wire cable types
in addition to standard screw terminals types
Features
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Be sure to read Safety Precautions on pages 83 to 88 and
Safety Precautions for All Limit Switches.
Select based on the operating temperature
Ambient operating temperature of 5°C to 120°C: Heat-resistant type (WL@-TH-N/WL@-TH)
Ambient operating temperature of -40°C to 40°C: Cold-resistant type (WL@-TC-N/WL@-TC)
Select based on the operating environment
Outdoor use: Weather-resistant type (WL@-P1-N/WL@-P1)
Chemicals and oils: Corrosion-resistant type (WL@-RP-N/WL@-RP)
Coolant drops and mist: Coolant-resistant type (WL@-RP60-N/WL-RP60)
Mist Molded terminal 139 type (WL@-139-N/WL@-139)
The SC connector can be removed, so it is possible to use flexible conduit for the cable.
Constant water drops and mist Molded terminal 140 type (WL@-140-N/WL@-140)
Constant water drops or splattering cutting powder Molded terminal 141 type (WL@-141-N/WL@-141)
Molded terminal 145 type (WL@-145-N/WL@-145)

Characteristics
Note: The above figures are initial values.
*1. The values are calculated at an operating temperature of +5°C to +35°C, and an operating humidity of 40% to 70%RH. Contact your OMRON
sales representative for more detailed information on other operating environments.
*2. Except Switches with Flexible Rod Actuators.
*3. 500,000 operations min. for Weather-resistant models.
*4. In case of models without operation indicators.
*5. For low-temperature models this is -40°C to +40°C (with no icing). For heat-resistant models the range is +5°C to 120°C.
* Except models with operation indicators.
Circuit Configuration/Terminal Connection Diagram
Note: Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current
is higher than the leakage current.
For countermeasures, refer to technical support on your OMRON website.
* Light-ON when not operating means the operation indicator is lit when the actuator is free and is not lit when the actuator rotates or is pushed
down, and the Switch contacts contact to NO.
The above shows details of the switch interior. External wires (external resistances) are not shown. For details, refer to Operation on page 18.

* The WL-2H1100-K, WL-2H2100-K, and WL-2H4100-K correspond with each set model WLG@, the design of which was changed in April 2019.
Please inquire if you desire a single-item head manufactured before the design change. On products that underwent the design change in April
2019, the front of the switch box cover at the bottom front has a protruding shape, and on earlier products has a depressed shape.

Connector (Conduit size: JIS B0202G1/2)
Note: 1. Please use sealling tape with SC Connectors. SC-1M to SC-5M, however, are provided with an O-ring (NBR) and therefore sealing tape
is not necessary to ensure a proper seal. The SC-6 and SC-P2 models are made of resin. If higher sealing performance is required, use
one of SC-1M to SC-5M, which have metal connectors.
2. Unless otherwise indicated, a tolerance of ±0.4 mm applies to all dimensions.
