Features

Many Variations in Standard Limit Switches A Wide Range of Models The series includes includes many different actuators that you select to match the workpiece shape and motion, and a wide range of Switch variations, such as models with operation indicators for easier working and maintenance and models with different types of connectors. Select from Six Types of Environment Resistance The series includes Airtight Switches, Hermetic Switches, Heat- resistant Switches, Low-temperature Switches, Corrosion-proof switches, and Weather-proof Switches. You can select the model based on the onsite environment. Excellent Performance on Arc Welding Lines or Sites with Spattering Cutting Powder Ideal for Welding Sites These Switches use stainless steel or resin to prevent the adhesion of spatter. They can be used to reduce problems caused by zinc power generated during welding. Mechanical Endurance of 30 Million Operations Long-life Models for High-frequency Applications A mechanical durability of 30 million operations minimum is provided. The head features a double-seal structure with a head cap and oil seal. DPDB Operation The double-pole, double-break structure ensures circuit braking. Degree of Protection; IP67 Approved Standards to Aid Export Machines The Switches are certified for EN/IEC, UL, cUL, and CCC making them ideal for export machines. Applicable to Either Standard Loads or Microloads Standard-feature gold-clad contacts provide high reliability. The use of a high-contact-pressure crossbar structure also increases reliability. Easy to Work With Downsizing of the built-in switch has increased the space to house the wiring. The insulating paper that was often in the way when wiring has been eliminated. Nickle-plated steel screws are used for the terminal screws. The screws adhere to magnetized screwdrivers to prevent dropping and loosing them. Models with Connectors to Reduce Wiring A neon lamp or LED indicates the operating status. The 3D structure of the lamp cover disperses light so you can check the operating status from the side.

Screw Terminal Switches Screw Terminal Switches Indicator-equipped (Light-ON when Not Operating) Switches *1 Direct-wired Connectors/Pre-wired Connectors Indicator-equipped (Light-ON when Not Operating) Switches *1 Note: Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current is higher than the leakage current. For countermeasures, refer to technical support on your OMRON website. *1. Light-ON when not operating means the indicator is lit when the actuator is free and is not light when the Switch contacts (NO) close when the actuator rotates or is pushed down. *2. The position of the positioning piece is not always the same. If using an L-shaped connector causes problems in application, use a straight connector.

Cover Cover Seal High sealing performance is achieved. The seal also serves as a spacer. There is no troublesome insulating paper, making it easy to work with the Switch. Head-mounting Screws Head You can remove the two screws to mount the switch in any of the four possible orientations. Shaft Section Seal An oil seal is fitted on the inlet of the shaft section to maintain a tight seal. You can change the direction of the operational plunger to electrically switch the direction of operation between both sides, left only, or right only. Operational Plunger Built-in Switch Built-in switch with SPST -NO+NC contact form. Terminal Screws Four, M3.5 screws Conduit Opening *1 The conduit screw is a parallel screw for G1/2 piping, and is used together with an SC connector to maintain a tight seal. Roller Actuator The roller is made of self-lubricating sintered stainless steel and boasts high resistance to wear. Lever The lever is forged from corrosion-resistant aluminum alloy. It provides superior corrosion resistance and outstanding strength. With roller lever, adjustable rod and flexible rod models, the actuator position can be set anywhere within 360°. (The lever cannot be mounted in the opposite direction.)

Note: 1. Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current is higher than the leakage current. For countermeasures, refer to technical support on your OMRON website. *1. Light-ON when operating means that the lamp lights when the Limit Switch contacts (NC) release, or when the actuator rotates or is pushed down. *2. Light-ON when not operating means the lamp remains lit when the actuator is free, or when the Limit Switch contacts (NO) close when the actuator rotates or is pushed down. Indicators Indicator The indicator is either a neon lamp or an LED. Switches with LED indicators have a built-in rectifier stack, so there is no connection polarity. Contact Spring Use the terminal screws on the built-in switch to connect to the lamp terminals. A coil spring is used to make contact, so connecting to the lamp terminals is not necessary. Indicator Covers The indicator covered if outsert molded from diecast aluminum and has outstanding sealing properties. Indicator Windows Operating status (i.e., light-ON when operating or light-ON when not operating) depends on whether a neon lamp or an LED is used. Indicators can be switched from light-ON when operating and light-ON when not operating, by simply rotating the indicator holder by 180°.

• Be sure to ground. If not, there is the possibility that electrical shock occurs.
• Do not touch charged switch terminals while the switch has carry current, otherwise there is the possibility that electrical shock occurs.
• Do not disassemble the limit switch or touch inside of it under supplying power, otherwise there is the possibility that electrical shock occurs.
• Do not touch the wire or rod type actuator in order to prevent injury.
• Connect a fuse which has 1.5 to 2 times higher breaking current than the switch rated current to the switch in series in order to prevent the switch from short-circuit damage. On the occasion when using the switch with GB ratings, use a 10A fuse that complies IEC60269, either type gG.
• The durability of switch is depends on the operating condition. Be sure to check the condition with actual using condition before using, and use with the number of times of operating without a performance problem.
• Do not drop the switch. Otherwise, there is the possibility that the switch functions may be spoiled.
• Do not connect a Single Limit Switch to two power supplies that are different in polarity or type.
• Be sure to keep the load current less than the rated value. Otherwise, there is the possibility that the switch may be damage and/or burnout.
• Minimum operating load: 5 VDC 1 mA, resistive load, P level Note: The P level indicates the standard malfunction level at a reliability level of 60% (λ60). (JISC5003) λ60 = 0.1 × 10 -6 per operation, which indicates an estimated malfunction of 1 out of every 10,000,000 operations at a reliability level of 60%.
• Do not use the Switch by itself in atmospheres containing flammable or explosive gases. Arcs and heating resulting from switching may cause fire or explosion.
• Be sure to prevent the foreign materials such like a scrapped cable intrusion in to the switch when wiring. Otherwise, there is the possibility of spoiling the normal operation.
• Never wire to the wrong terminals.
• Do not store or use the switch with following place. Where the temperature fluctuates greatly Where the humidity is very high and condensation may occur. Where the vibration is too much Where receiving direct sunshine. Where receiving salty wind.
• Do not disassemble and/or modify the switch at anytime. Otherwise, there is the possibility of spoiling the normal operation.
• Do not apply the force such like deformation and/or degeneration to the switch. Otherwise, there is the possibility that the switch functions may be spoiled. Environment
• Take special care to use where there is fine powder, mud and/or foreign materials stacking. And check the condition with actual using condition before using. Then use without a performance problem.
• This switch is only for indoor use. If it is used in outdoor, it may be cause of switch failure.
• Do not keep the Switch in locations with corrosive gas, such as sulfuric gas (H2S or SO2), ammonium gas (NH3), nitric gas (HNO3), or chlorine gas (Cl2), or high temperature and humidity. Otherwise, contact failure or corrosion damage may result.
• Seal material may deteriorate if a Switch is used outdoor or where subject to special cutting oils, solvents, or chemicals. Always appraise performance under actual application conditions and set suitable maintenance and replacement periods.
• Install Switches where they will not be directly subject to cutting chips, dust, or dirt. The Actuator and Switch must also be protected from the accumulation of cutting chips or sludge.
• Constantly subjecting a Switch to vibration or shock can result in wear, which can lead to contact interference with contacts, operation failure, reduced durability, and other problems. Excessive vibration or shock can lead to false contact operation or damage. Install Switches in locations not subject to shock and vibration and in orientations that will not produce resonance.
• The Switches have physical contacts. Using them in environments containing silicon gas will result in the formation of silicon oxide (SiO 2) due to arc energy. If silicon oxide accumulates on the contacts, contact interference can occur. If silicon oil, silicon filling agents, silicon cables, or other silicon products are present near the Switch, suppress arcing with contact protective circuits (surge killers) or remove the source of silicon gas. Installing the Switch
• To install the Switch, make a mounting panel, as shown in the following diagram, and tighten screws using the correct torque. Precautions for Safe Use Precautions for Correct Use Not Suitable Suitable +0.2 +0.2 Front Mountig : Four, 5.2 dia. holes or M5 tapped holes Rear Mountig : Four, 6.2 dia. holes ±0.1530.2 58.7±0.15

• If screws are too loose they can lead to an early malfunction of the Switch, so ensure that all screws are tightened using the correct torque.
• In particular, when changing the direction of the Head, make sure that all screws are tightened again to the correct torque. Do not allow foreign objects to fall into the Switch. Wring In the case of mounting screw
• Use M3.5-nylon insulation covered crimp terminals (round type) for wiring.
• Appropriate wire size is AWG16 (1.25mm2).
• Do not supply electric power when wiring. Otherwise electric shock may result.
• Do not pull out the wires with excessive force. It may cause of coming off the wire.
• Use crimp terminals for wiring.
• In the case of lump unit, to avoid interference between lump unit and crimp terminals, wire according to right wiring figure. Attach the lump unit spring to terminal screw certainly otherwise itÅfs possible to be destroyed or shorted.
• The ground terminal is only installed on models with ground terminals. In the case of prewired connecter and direct connecter
• Holding the connecter certainly when pulling connecter.
• Don’t pull the cable holding it. How to handle Changing direction of the head
• By removing the screws in the two corners of the head, the head can be set any of four directions. Be sure to change the plunger for internal operations at the same time. Built-in Switch
• Do not remove or replace the built-in switch. Overtravel Markers
• All Switches with Roller Lever Actuators except for Switches with Fork Lever Locks and Low-temperature Switches have a set position marker plate.
• To allow the roller lever type actuator to travel properly, set the roller lever according to the dog or cam stroke so that the arrowhead of the lever is positioned within overtravel markers as shown. Connectors
• Tighten the connector with the appropriate torque to prevent deformation.
• Use the OMRON type SC connector series, which is prepared separately, suitable for outer diameter of cable and inner diameter of seal rubber.
• Make sure to wrap the connector with the seal tape, except the connector which has O-ring, to keep the sealability.
• To conform to CSA, use a CSA certified water tight treated conduit hub.
• Even when the connector is assembled and set correctly, the end of the cable and the inside of the Switch may come in contact. This can lead to malfunction, leakage current, or fire, so be sure to protect the end of the cable from splashes of oil or water and corrosive gases. Microload Applications
• The switch contacts can be used both for standard loads and microloads, but once a contact has been used to open and close a load it can no longer be used for lower loads. Doing so will damage the contact surface and reduce contact reliability.
• If an inrush current or other sudden load occurs during a switch operation, the switch will begin to degrade severely which can result in reduced durability. Use a contact protection circuit if required. Indicator Indicator-equipped switch has contacts and indicator in parallel. When contacts are open, leakage current flows through the indicator circuit and may cause load's malfunction. Please check the load's OFF current before use the indicatorequipped switch. Leakage current may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current is higher than the leakage current. For countermeasures, refer to technical support on your OMRON website. Terminal Plate

Using a WL@-2N Switch Mounted from the Side If you replace a previous Switch with a WL@-2N-N Switch, a Mounting Plate (sold separately) is available to maintain mounting compatibility. If you use the Mounting Plate, the Switch mounting holes and actuator position will be compatible. (The position of the dog will not need to be changed.) Operation

• Carefully determine the position and shape of the dog or cam so that the actuator will not abruptly snap back, thus causing shock. In order to operate the Limit Switch at a comparatively high speed, use a dog or cam that keeps the Limit Switch turned ON for a sufficient time so that the relay or valve will be sufficiently energized.
• The method of operation, the shape of the cam or dog, the operating frequency, and the travel after operation have a large influence on the durability and operating accuracy of the Limit Switch. The cam or dog must be smooth in shape.
• Appropriate force must be imposed on the actuator by the cam or dog in both rotary operation and linear operation. If the dog touches the lever as shown below, the operating position will not be stable.
• Unbalanced force must not be imposed on the actuator. Otherwise, wear and tear on the actuator may result.
• With a roller actuator, the dog must touch the actuator at a right angle. The actuator or shaft may deform or break if the dog touches the actuator (roller) at an oblique angle.
• Make sure that the actuator does not exceed the OT (overtravel) range, otherwise the Limit Switch may malfunction. When mounting the Limit Switch, be sure to adjust the Limit Switch carefully while considering the whole movement of the actuator.
• The Limit Switch may soon malfunction if the OT is excessive. Therefore, adjustments and careful consideration of the position of the Limit Switch and the expected OT of the operating body are necessary when mounting the Limit Switch.
• When using a pin-plunger actuator, make sure that the stroke of the actuator and the movement of the dog are located along a single straight line. Others
• For long term (over a year) storage, check according to Operating characteristics, Contact resistance and Dielectric strength at least. And check with using condition.
• The durability of the Switch is greatly affected by operating conditions. Evaluate the Switch under actual working conditions before permanent installation and use the Switch within a number of switching operations that will not adversely affect the SwitchÅfs performance. 30.2 58.7 WL@-2N Mounting Plate Replacing a Switch with the WL@-2N-N Mounting Plate Set

Operation of Fork Lever Locks A Switch with a Fork Lever Lock is constructed so that the dog pushes the lever to invert the output and this inverted state is maintained even after the dog moves on. If the dog then pushes the lever from the opposite direction, the lever will return to its original position. Adjusting the Length of the Rod or Lever The length of the rod or lever can be adjusted by loosening the Allen-head bolt. Adjustable Roller Levers: (WLCA12-N, WLCA12-2-N, WLCA12-2N-N, WLG12-N) Adjustable rod lever: (WLCL-N, WLCL-2-N, WLCL-2N-N, WLGL-N, WLCAL4-N) Selecting the Roller Position There are four types of Switches with Fork Lever Locks for use depending on the roller position.

Connectors (SC Series) Cabtire cables and flexible tubes with various diameters are used to connect machine tools and controllers with Limit Switches. To ensure the watertightness of the edges of the conduits, use an SC Connector that is suitable for the external diameter of cable and model of Limit Switch. Connector for Cabtire Cable Note: Please use sealling tape with SC Connectors. SC-1M to SC-5M, however, are provided with an O-ring (NBR) and therefore seal ing tape is not necessary to ensure a proper seal. Simple Connectors (Not Suitable for Locations Subject to Oil or Water) Note: Simple connector are made of resi n. If more sealing capability is required, use one of SC-1M to SC-5M, which have metal casings. Models marked with an asterisk (*) however, can only be used with resin connectors.
