WL-N Series limit switches simplify installation
Models focus on the most popular features to make stocking easier.
• Improved durability and performance
• Applicable to either standardloads or microloads
•LED with3D light-dispersing structure
• Reduced part numbers
• Easy wiring
• Direct and pre-wiring
• Ground terminal models are approved by EN andIEC and bear the CE marking UL,CSA

*1The values are calculated at an operating temperature of 5 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.
*2Durability is 1,000,000 operations min. for high-sensitivity models. 500,000 operationsmin. for weather-proofmodels.
*3Durability is 500,000 operations min. for high-sensitivity models. 500,000 operations min. for weather-proofmodels.
*4For low-temperature models this is –40 to 40°C (with no icing). For heatresistant models the range is 5 to 120°C.
Note:1. The above figures are initial values.
2. The figures in parentheses for dielectric strength are those for the highsensitivity overtravel models.
