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. 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. Contact Spring Light-ON when Not Operating Indicator up Light-ON when Not Operating Indicator down Spatter-prevention Switches Light-ON when Operating Lamp Holder The built-in switch's terminal screws are used to connect the indicator terminal. Since the connection spring (coil spring) is used for this connection, it will not be necessary to connect the indicator terminal. When a ground terminal is provided however, a lead wire must be used. Environment-resistant Switches Light-ON when Operating/Not Operating Indicators can be switched from light-ON when operating and light-ON when not operating, by simply rotating the indicator holder by 180. (However, Direct-wire connector, Pre-wired Connector, Three-core, and Four-core Switches cannot be switched to light-ON when operating (NC wiring).)

For countermeasures, refer to technical support on your OMRON website. 2. For details on accessories (sold separately), refer to page 79. *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. *3. The wiring varies depending on when the loads and indicator lamps are operating. For contacts that include an internal circuit (indicator circuit), connect a resistor for protection. To find the resistance value and capacity, calculate using the voltage, current, and power that is actually used. * Resistance () = Voltage (V) / Current (I) * Power (W) = Current (A) x Voltage (V) * Capacity (W) = Power (W) x Margin (approximately 2x) Use the values below for reference. Reference: Example of Protection Resistance The capacity value is a numerical value that does not account for the margin. Select a resistor with sufficient capacity. When calculating using the leakage current in this catalog, the display becomes slightly dim. Use of a current that is at least around twice the leakage current is recommended.

Connector Pin Layout Diagram AC Positioning piece * DC Positioning piece * 2 2 3 1 4 3 Safety Precautions * Light-ON when not operating means the operation 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. The above shows details of the switch interior. External wires (external resistances) are not shown. For details, refer to Operation on pages 18. 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 4 * 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. 69 WL-N/WL Structure and Nomenclature WLMCA2-N Shield Structure Head Cap The head cap helps prevent the entry of cutting chips.You can use the protrusion on the cap to confirm the set position. A head cap and oil seal form a double-seal structure. Excellent durability and reliability are ensured. Oil seal Actuator Roller The roller is made of self-lubricating sintered stainless steel. It provides superior resistance to wear. Head cap Lever The lever is forged from anti-corrosive aluminum alloy. It provides superior corrosion resistance and outstanding strength. With a roller lever actuator, the actuator position can be set anywhere within 360. (The lever cannot be mounted in the opposite direction.) Head You can remove the two screws to mount the head in any of the four possible directions. Operating Plunger Built-in Switch PEEK resin is used. It provides superior resistance to wear. You can change the mounting direction to use any one of the three operating directions (both sides, left side, or right side). Built-in switch with an SPST-NO+NC contact form. Main unit 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. Terminal Screws Four, M3.5 screws. Cover Setscrew Conduit Opening In addition to parallel threads for G1/2 tubing, direct-wired and pre-wired connector types are available. 70 Cover A combination Philips-slotted screw is used. A retainer prevents the screw from falling from the cover even when the screw is loose. WL-N/WL Set Position Marker Plate Release Plunger The set position is easy to view. Hardening method changed for greater abrasion resistance. Standard Model Long-life Model Sintered alloy Stainless steel + Hardening The stroke is indicated in fluorescent color that is visible from the slit in the rubber cap. General-purpose Switches WLMGCA2 Head Fluorescent paint Requires maintenance (excessive overtravel) Proper range Requires maintenance (insufficient overtravel) Proper range Shaft Section Seal By fitting a double seal consisting of an oil seal and an X-ring to the rotary shaft, even greater sealing properties are achieved. X-ring Actuator Head Mounting Screws Roller The roller is made of self-lubricating stainless sintered and boasts high resistance to wear. Lever The lever forged of anti-corrosive aluminium alloy features high corrosion resistance and outstanding ruggedness. With roller lever models, the actuator position can be set anywhere within 360. (The lever cannot be mounted in the opposite direction.) Smoother Movement A grease holder is provided on the shaft to prevent the grease from running out. Standard Model Operational Plunger Cover Seal Terminal Screws Grease holder Four, M4 screws Smooth movement is achieved using olefin grease. (Standard models use molybdenum disulfide grease.) Cover Separator Bearing The separator has outstanding insulation properties and prevents the generation of any gases which may corrode the internal parts. The bearing smooths the plunger movement. Cover Mounting Screw Conduit Opening In addition to parallel threads for G1/2 tubing, direct-wired and pre-wired connector types are available. A combination Phillips-slotted screws are used to ensure ease of use. Accessories Built-in Switch Built-in switch with SPST-NO+NC contact form. Long-life Switches By using a packing seal as the cover seal, an optimum squeeze can be obtained and high sealing properties are assured as well. Long-life Model Spatter-prevention Switches Oil seal Requires maintenance (excessive overtravel) Environment-resistant Switches The Head can be mounted in any of the four directions by removing the screws at the four corners of the Head.

Indicates an action that must be performed or avoided for preventing operation failure or malfunction of the product or adverse impact on performance or functionality. * This switch is only for indoor use. If it is used in outdoor, it may be cause of switch failure. * 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. * 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. Not Suitable Suitable * To install the Switch, make a mounting panel, as shown in the following diagram, and tighten screws using the appropriate tightening torque. Long-life Switches Installing the Switch Spatter-prevention Switches * 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 (SiO2) 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 suppressor) or remove the source of silicon gas. Environment-resistant Switches Precautions for Safe Use Front Mounting : Four, 5.2 +0.2 0 dia. holes or M5 tapped holes 58.70.15 Rear Mounting : Four, 6.2 +0.2 0 dia. holes 30.2 0.15 Accessories Safety Precautions * Be sure to ground. Otherwise electric shock may result. * Do not touch charged switch terminals while the switch has carry current, Otherwise electric shock may result. * Do not disassemble the limit switch or touch inside of it under supplying power, Otherwise electric shock may result. * Do not disassemble or touch the inside while the power is turned on. Otherwise electric shock may result. * Do not touch the wire or rod type actuator in order to prevent injury. Doing so may result in 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 EN/IEC/GB ratings, use a 10 A 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. * Otherwise, there is the possibility of spoiling the normal operation. Do not drop the switch. * Do not connect a Single Limit Switch to two power supplies that are different in polarity or type. Risk of interference. * 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. * 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. * Using the Switch in a pressed-in state for an extended period of time can accelerate part deterioration and also lead to failure to return to the original position. Check the Switch beforehand, and perform periodic inspection and replacement. * 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. Where exposed to cutting powder, machining chips, oil, and chemicals inside the protective doors. Where exposed to cleansers, thinners, and other solvents * Do not use or store 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. * 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. * If the Switch will not be switched ON or OFF for an extended period of time, contact reliability may degrade due to oxidation of the contact points, resulting in inadequate conductivity, which could lead to an accident. Precautions for Correct Use Operating Environment General-purpose Switches For the Safety Precautions for All Limit Switches, refer to the OMRON website. 81 WL-N/WL Appropriate Tightening Torque * If screws are too loose they can lead to an early malfunction of the Switch, so ensure that all screws are tightened using the appropriate tightening torque. * In particular, when changing the direction of the Head, make sure that all screws are tightened again to the appropriate tightening torque. Do not allow foreign objects to fall into the Switch.

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. For the WL-N, the P level is at the min. operating load of 5 VDC and 1 mA resistive load. Note: The P level indicates the standard malfunction level at a reliability level of 60% (60). (JISC5003) 60 = 0.1x10-6/ operations indicates that the estimated malfunction rate is less than 1/10,000,000 operations with a reliability level of 60%. 82 In the case of mounting screw Basic models * Use M3.5-nylon insulation covered crimp terminals (round type) for wiring. Ex.) N1.25-M3.5 (RAP1.25-3.5) (J.S.T. Mfg. Co.,Ltd.) * Appropriate wire size is AWG16 (1.25 mm2). * 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. * Avoid connecting the wires directly to the terminal. Instead, attach using a crimp terminal. * In the case of indicator unit, to avoid interference between lump unit and crimp terminals, wire according to right wiring figure. * Attach the indicator unit spring to terminal screw certainly, otherwise it's possible to be destroyed or shorted. * The ground terminal is only installed on models with ground terminals. In the case of prewired connector and direct connector * Holding the connector certainly when pulling connector. * Don't pull the cable holding it. How to handle Changing direction of the head * By removing two head screws or four head screws, mounting in any of four orientations is possible. 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. Risk of malfunctioning. Overtravel Markers * All Switches with Roller Lever Actuators except for Switches with Fork Lock Levers 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 the overtravel markers (pages 15, 16). This enables usage in the optimum state. WL-N/WL Terminal Plate By using the Terminal Plate (sold separately), as shown in the following diagram, the Switch can be used as a single-polarity doublebreak switch. Use in basic and high-sensitivity switches that are general-purpose, environment-resistant, spatterprevention, and long-life WL-N TERMINAL PLATE Attach the Terminal Plate so that the "COM" mark is oriented as shown on the left. Terminal Plate Terminal Plate Mounting Diagram (with Two Terminal Screws Removed) Use in long-life high-sensitivity switches To customers using the WL@-2N series model in a sidemounted configuration We provide a special mounting plate (sold separately) that features mounting compatibility when replacing with the WL@-2N-N series.

Environment-resistant Switches * The connector must be tightened at a suitable tightening torque (1.77 to 2.16 N). Tightening with excessive torque could damage the case. * Select the connector based on the sealed rubber inner diameter for matching the cable outer diameter. For details, refer to Accessories (Sold Separately) - Connector (Conduit size: JIS B0202G1/2) on page 77. * When mounting the connector, use seal tape (not needed if the connector includes an O-ring) on the threaded section of the connector to ensure sealing performance. * To ensure compliance of this Switch with the CSA standards, use of a waterproof connector compliant with the CSA is recommended. * Using an inappropriate connector or assembling Switches incorrectly (assembly, tightening torque) can result in malfunction, leakage current, or fire, so be sure to read the connector instruction manual thoroughly beforehand. * 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. * The following wiring is recommended for preventing the entry of fluids from the conduit opening. General-purpose Switches Conduit opening preparation Microload Applications Accessories * The WL-N basic model, WL high-sensitivity model, and highprecision model 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. Operaition indicator Safety Precautions 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. 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. 83 WL-N/WL Operation Procedures 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. Incorrect * Mount so that the actuator travel after operation (OT) is not exceeded. If the travel after operation (OT) exceeds the limit, switch failure could result. When mounting the Limit Switch, be sure to adjust the Limit Switch carefully while considering the whole movement of the actuator. Operating body PT (Pretravel) Install a stopper. 70% of 100% of rated OT rated OT FP (Free position) OP (Operating position) OT (Overtravel) TTP (Total travel position) Optimum setting range Correct Distance to the optimum setting range. Snapped back Abruptly actuated Reference line Incorrect Correct * 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. Correct Snapped back Abruptly actuated Stopper * 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. Incorrect Correct Dog * 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. Incorrect Dog Correct Operating body Operating body * Unbalanced force must not be imposed on the actuator. Otherwise, wear and tear on the actuator may result. Incorrect Correct Others Dog Dog Roller Roller * 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. Incorrect Dog 84 Correct Dog * If the Switch will be left in a location outside the storage environment conditions, if condensation has formed, or after longterm storage exceeding one year, at the minimum, check the operating characteristics, contact resistance, insulation resistance, and dielectric strength, and conduct a check under the operating conditions. * If using normal open (NO), be sure to fully press in the actuator. The proper press-in depth is about 60% to 80% of the entire motion (TT). * Conduct periodic inspection on a regular schedule.
