General-purpose Switches
A Wide Range of Models
You can select the optimum product for the workpiece shape and movement from a variety of actuators, including Roller Lever, Plunger, Flexible Rod, and Fork Lock Lever Switches.
Environment-resistant Switches
Six environment resistant models are available
Airtight Switches, Hermetic Switches, Heat-resistant Switches, Low-temperature Switches, Corrosion-proof Switches, and Weather-proof Switches are available.
You can select the model based on the onsite environment.
Spatter-prevention Switches
Ideal for Welding Sites
Uses stainless steel and plastic materials that prevent the adhesion of spatter.
They can be used to reduce problems caused by zinc power generated during welding.
Long-life Switches
Long-life Models for High-frequency Applications
A mechanical durability of over 30 million cycles is achieved by improving slidability and the wear resistance of the head.
Features Common
DPDB Operation
The two-circuit double-break structure ensures circuit braking.
• Basic/Retention type Switches (WL-N)
• High-sensitivity/High-precision Switches (WL)
Degree of Protection; IP67
Models with Connectors to Reduce Wiring
A neon lamp or LED indicates the operating status. This makes startup checks and maintenance easy.
Sensor I/O Connector Models to Match Wiring Specifications
Direct-wire types and pre-wired types are available for easy replacement of limit switches.

* The standard cable length for a pre-wired connector is 0.3 m. Contact your OMRON representative for information on
other cable lengths.
Note: The default setting is light-ON when not operating (NO wiring).
Turn the lamp holder by 180° to change the setting to light-ON when operating (NC wiring).
(However, Three-core and Four-core Switches cannot be switched to light-ON when operating (NC wiring).)

Limit Switch Connectors
Connectors (SC Series)
Cabtire cables and flexible tubes with various diameters are used to connect machine tools and controllers with Limit Switches. To ensure the watertightness of the edges of the conduits, use an SC Connector that is suitable for the external diameter of cable and model of Limit Switch.
