5 / 43 page 5 WL/WLM Selection Guide With the WL Series, OMRON will combine the switch, Actuator, and wiring method required to build the ideal switch for your application. *1. Not all functions can be combined with environment-resistant switches. Refer to the applicable models on the previous page. *2. Refer to page 25 for information on the construction of Hermetic Switches. The WL Series consists of four basic types: General-purpose, En- vironment-resistant, Spatter-prevention, and Long-life Switches. WLCA2 Switches can be used for the most common applications. Normal High-temperature Low-temperature Outdoors −10°C +80 °C +5 °C +120 °C −40°C +40 °C Water-resistant to IP67. Environment Key specifications Models WL @ General-purpose Switches WLM @ Long-life Switches WL @-TH Heat-resistant Switches *1 WL @-TC Low-temperature Switches *1 WL @-P1 Weather-proof Switches *1 Water drops and mist Uses an airtight built-in switch. WL @-55 Airtight Switches *1 WL @-RP Corrosion-proof Switches *1 WL @-S Spatter-prevention Switches Chemicals and oil WL @-139 Hermetic, Molded-terminal Switches *1, *2 WL @-RP40 Hermetic, Molded-terminal Switches *1, *2 WL @-140 Hermetic, Molded-terminal Switches *1, *2 WL @-141, -145 Hermetic, Molded-terminal Switches *1, *2 (Only the WLCA2, WLG2, WLGCA2, and WLH2 can be produced.) WL @-RP60 Hermetic, Molded-terminal Switches *1, *2 According to Operating Environment To increase heat resistance, the rubber material (silicon rubber) and the material of the built-in switch have been changed. Cables attached. Uses a general-purpose built-in switch. The case cover and conduit opening are molded from epoxy resin to increase the seal. The cover cannot be removed. Cables attached. Uses an airtight built-in switch. The cover screws, case cover, box interior, and conduit opening are molded from epoxy resin to increase the seal. (The cover cannot be removed.) Cables attached. Uses an airtight built-in switch. The cover screws, case cover, box interior, conduit opening, box head, and head screws are molded from epoxy resin to increase the seal. (The cover cannot be removed.) The Head opening is protected from cutting powder. -141: The Head section is molded from epoxy resin; Head direction cannot be changed. -145: The Head section is molded from epoxy resin; Head can be in any of 4 directions. Cables attached. Uses an airtight built-in switch. The case cover and box interior are molded from epoxy resin to increase the seal. The cover cannot be removed. The SC connector can be removed, so it is possible to use flexible conduits for the cable. To prevent spatter during welding, a heat-resistant resin is used for the indicator cover and screws and rollers are all made from stainless steel. Cables attached. Uses an airtight built-in switch. The case cover, box interior, conduit opening, and head screws are molded from epoxy resin to increase the seal. (The cover cannot be removed.) Rubber parts are made from fluorine rubber to increase resistance to coolant. 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. Corrosion-proof aluminum diecast has been used for the housing, fluorine rubber has been used for rubber parts, and stainless steel has been used for screws and nuts (except for actuator) to increase resistance to oils, chemicals, and weather. To increase resistance to cold, silicon rubber and other measures are used. Constant water drops and mist Coolant Spattering from welding Constant water drops or splattering cutting powder |
