Two-circuit Limit Switch/Long-life Two-circuit Limit Switch WL-N/WLM-N Select the Best Two-circuit Switch for the Operating Environment and Application from a Wide Range of Models A wide selection of models is available, including general-purpose, environment-resistant, and spatter- prevention switches. Standard-feature gold-clad crossbar contacts provide high reliability. Applicable to either standard loads or microloads. Switches with lever actuators provide 90 overtravel, one-side operation, and four-direction head mounting. Approved standards: EN/IEC, UL, cUL, and CCC. Contact your OMRON representative for information on approved models. Be sure to read Safety Precautions on page 44 to 48 and Safety Precautions for All Limit Switches. Features Standard Switches Features Common to All Switches Many Variations in Standard Limit Switches DPDB Operation A Wide Range of Models The double-pole, double-break structure ensures circuit braking. The series includes includes many different actuators that you select 11 13 to match the workpiece shape and motion, and a wide range of Switch 12 14 variations, such as models with operation indicators for easier Za (NO)14 13(NO) working and maintenance and models with different types of connectors. (NC)12 11(NC) Load Load Environment-resistant Switches Select from Six Types of Environment Resistance Degree of Protection IP67 The series includes airtight switches, hermetic switches, heat- Approved Standards to Aid Export Machines resistant switches, low-temperature switches, corrosion-proof switches, and weather-proof switches. You can select the model The Switches are certified for EN/IEC, UL, cUL, and CCC making based on the onsite environment. them ideal for export machines. Applicable to Either Standard Loads or Microloads Spatter-prevention Switches Standard-feature gold-clad contacts provide high reliability. Excellent Performance on Arc Welding Lines or Sites with The use of a high-contact-pressure crossbar structure also increases Spattering Cutting Powder reliability. Ideal for Welding Sites Easy to Work With These Switches use stainless steel or resin to prevent the adhesion Downsizing of the built-in switch has increased the space to house the of spatter. wiring. They can be used to reduce problems caused by zinc power The insulating paper that was often in the way when wiring has been generated during welding. eliminated. Nickle-plated steel screws are used for the terminal screws. Long-life Switches The screws adhere to magnetized screwdrivers to prevent dropping and loosing them. Mechanical Endurance of 30 Million Operations Long-life Models for High-frequency Applications Models with Connectors to Reduce Wiring A mechanical durability of 30 million operations minimum is provided. A neon lamp or LED indicates the operating status. The head features a double-seal structure with a head cap and oil The 3D structure of the lamp cover disperses light so you can check seal. the operating status from the side. 1WL-N/WLM-N Product Configuration Basic Switches WLC -N High-sensitivity Switches WLG -N Standard High-precision Switches WLGCA2-N Protective Switches WLCA32- -N General-purpose Indicator-equipped Switches: Neon lamps WL -LE-N Operation indicators Indicator-equipped Switches: Light emitting diodes (LED) WL -LD-N Direct-wired Switches WL- LDK -N Sensor I/O connectors Pre-wired Switches WL - LD-M1 -N WL - LD-AGJ-N WL - LD-DGJ-N WL - LD-DK1EJ-N Airtight Switches WL -55-N Hermetic Switches WL -139-N WL -140-N WL -141-N WL -145-N WL -RP40-N WL -RP60-N Environment-resistant Heat-resistant Switches WL -TH-N Low-temperature Switches WL -TC-N Corrosion-proof Switches WL -RP-N Weather-proof Switches WL -P1-N Basic Switches WLC - S-N Spatter-prevention High-sensitivity Switches WLG - S-N High-precision Switches WLGCA2- S-N Basic Switches WLMCA2- -N Long-life High-sensitivity Switches WLMG2- -N High-precision Switches WLMGCA2- -N 2
