Features Standard Models Many Variations in Standard Limit Switches A Wide Range of Models The WL Series provides a complete range of Limit Switches with a long history of meeting user needs. Select environment-resistant specifications, actuators for essentially any workpiece, operating sensitivity matched to the workpiece, operation indicators to aid operation and maintenance, and various wiring specifications. Environment-resistant Models Select from Six Types of Environment Resistance The series includes Airtight Switches, Hermetic Switches, Heatresistant Switches, Low-temperature Switches, Corrosion-proof switches, and Weather-proof Switches. Select the one required by the onsite environment. Spatter-prevention Models Excellent Performance on Arc Welding Lines or Sites with Spattering Cutting Powder Ideal for Welding Sites Stainless steel and resins that resist adhesion of spatters are used to prevent troubles caused by zinc powder generated during welding. Long-life Models Mechanical Endurance of 0 Million Operations Long-life Models for High-frequency Applications Long life has been achieved by increasing the resistance to friction and creating better sliding properties in the head mechanism. Greater visibility is provided when setting with a fluorescent display for setting the stroke. Features Common to All Models DPDB Operation The double-pole, double-break structure ensures circuit braking. (NO)4 (NC)1 (NO) Degree of Protection; IP7 O-rings, cover seals, and other measures provide a water-proof, dripproof structure (IP7). Approved Standards to Aid Export Machines Various WL/WLM switches are approved by UL, CSA, TÜV, EN/IEC, and CCC making them ideal for export machines.

Uses the W-10FB- Airtight Built-in Switch. Note: Use the SC Connector for the conduit opening. Refer to page 2 for information on the environment-resistant construction of Switches with Hermetic Seals. Uses a general-purpose built-in switch. Silicone rubber is used for rubber parts such as the O-ring, gasket, etc. Uses a special built-in switch made from heatresistant resin. Silicone rubber is used for rubber parts such as the O-ring, gasket etc. Diecast parts, such as the switch box, are made of corrosion-proof aluminum. Rubber sealing parts are made of fluorine rubber which aids in resisting oil, chemicals and adverse weather conditions. Exposed nuts and screws (except the actuator section) are made of stainless steel. Moving and rotary parts such as rollers are made of sintered stainless steel or stainless steel. The Head, box, and cover are yellow. Rubber parts are made from silicone rubber, which has a high-tolerance to deterioration over time and changes in temperature. Rollers are made of stainless steel to improve corrosion resistance. Exposed nuts and screws are made of stainless steel. All models except the lowtemperature and heat-resistant models Note: Models can be produced using standard actuators. All models except the lowtemperature and heat-resistant models Note: Models can be produced using standard actuators. Only the WLCA2, WLGCA2, or WLH2 can be produced for the WL@-141 and WL@-14.

Silicon rubber, however, can generate silicon gas. (This can occur at room temperature, but the amount of silicon gas generated increases at higher temperatures.) Silicon gas will react as a result of arc energy and form silicon oxide (SiO2). If silicon oxide accumulates on the contacts, contact interference can occur and can interfere with the device. Before using a Switch, test it under actual application conditions (including the environment and operating frequency) to confirm that no problems will occur in actual. 4

Selection Guide With the WL Series, OMRON will combine the switch,, and wiring method required to build the ideal switch for your application. The WL Series consists of four basic types: General-purpose, Environment-resistant, Spatter-prevention, and Long-life Switches. WLCA2 Switches can be used for the most common applications. According to Operating Environment Environment Key specifications Models Ambient operating temperature Normal High-temperature Low-temperature 40 C 10 C Water-resistant to IP7. + C +40 C +80 C +120 C To increase heat resistance, the rubber material (silicon rubber) and the material of the built-in switch have been changed.

Ambient operating temperature 10 C to +80 C (with no icing) Ambient operating humidity % to 9%RH Weight Approx. 27 g (in case of WLCA2) Note: 1. The above figures are initial values. 2. The figures in parentheses for dielectric strength are those for the highsensitivity overtravel models. *1. The values are calculated at an operating temperature of + C to + C and an operating humidity of 40% to 70%RH. Contact your OMRON sales representative for more detailed information on other operating environments. *2. Durability is 10,000,000 operations min. for general-purpose or highsensitivity overtravel models. *. Durability is 00,000 operations min. for high-precision models. All microload models however, are 1,000,000 operations min. 21
