Two-circuit Limit Switch WL-N/WL Two-circuit limit switches that can be selected to match the operating environment and application Wide variety of head shapes, including Roller Lever, Plunger, Flexible Rod, and Fork Lock Lever Switches. You can select the optimum actuator shape for the workpiece shape and movement from a variety of actuators. In addition to general detection, we also have environment resistant models for harsh environments, sputter resistant models for welding processes, and long-life models for high-frequency use. 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 page 62 to 67 and Safety Precautions for All Limit Switches. Features General-purpose Switches Features Common A Wide Range of Models DPDB Operation You can select the optimum product for the workpiece shape and The two-circuit double-break structure ensures circuit braking. movement from a variety of actuators, including Roller Lever, Basic/Retention type Switches (WL-N) Plunger, Flexible Rod, and Fork Lock Lever Switches. 11 14 12 13 Za Environment-resistant Switches (NO)14 13(NO) Six environment resistant models are available (NC)11 12(NC) Airtight Switches, Hermetic Switches, Heat-resistant Switches, Low- Load Load temperature Switches, Corrosion-proof Switches, and Weather-proof Switches are available. High-sensitivity/High-precision Switches (WL) You can select the model based on the onsite environment. 1 4 2 3 Spatter-prevention Switches Za (NO)4 3(NO) Ideal for Welding Sites Uses stainless steel and plastic materials that prevent the adhesion (NC)1 2(NC) Load Load of spatter. They can be used to reduce problems caused by zinc power generated during welding. Degree of Protection IP67 Long-life Switches Models with Connectors to Reduce Wiring Long-life Models for High-frequency A neon lamp or LED indicates the operating status. This makes Applications startup checks and maintenance easy. A mechanical durability of over 30 million cycles is achieved by improving slidability and the wear resistance of the head. Sensor I/O Connector Models to Match Wiring Specifications Direct-wire types and pre-wired types are available for easy replacement of limit switches. 1WL-N/WL Product Configuration Head/Actuator Operating Characteristic Typical models WLC -N General- Standard *1 Roller Lever Actuators Basic Switches purpose High-sensitivity Switches WLG High-precision Switches WLGCA2 WLD -N Plunger Actuators Basic Switches WLSD -N WLNJ- -N Flexible Rod Actuators Basic Switches WLCA32-4 -N Retention type Switches Fork Lock Lever Actuator Indicator-equipped WLC -LE-N Operation indicators *1 Roller Lever Basic Switches Actuators Switches:Neon lamps High-sensitivity Switches WLG -LE High-precision Switches WLGCA2-LE Indicator-equipped Basic Switches WLC -LD-N Switches: Light emitting High-sensitivity Switches WLG -LD diodes (LED) High-precision Switches WLGCA2-LD Basic Switches WLD -LE-N Plunger Indicator-equipped WLSD -LE-N Actuators Switches: Neon lamps Indicator-equipped Basic Switches WLD -LD-N WLSD -LD-N Switches: Light emitting diodes (LED) Indicator-equipped Flexible Rod Basic Switches WLNJ- LE-N Actuators Switches: Neon lamps Indicator-equipped Basic Switches WLNJ- LD-N Switches: Light emitting diodes (LED) Indicator-equipped Retention type Switches WLCA32-4 LE-N Fork Lock Lever Actuator Switches: Neon lamps Indicator-equipped Retention type Switches WLCA32-4 LD-N Switches: Light emitting diodes (LED) Direct-wired Types WLCA2-LDK -N Sensor I/O connectors Roller Lever Basic Switches Actuators High-sensitivity Switches WLG2-LDK High-precision Switches WLGCA2-LDK Pre-wired Types WLCA2- LD-M1 -N Basic Switches WLCA2- LD-D J-N High-sensitivity Switches WLG2- LD-M1 WLG2- LD-D J High-precision Switches WLGCA2- LD-M1 WLGCA2- LD-D J Basic Switches WLD28- LDK -N Plunger Direct-wired Types Actuators Pre-wired Types Basic Switches WLD28- LD-M1 -N WLD28- LD-D J-N *1.
