WL-N/WLM-N Indicators Indicator Covers Indicator The indicator covered if outsert molded from diecast aluminum and has outstanding sealing properties. 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 Operating/Not Operating Lamp Holder 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-wired Connector, Pre-wired Connector, Three-core, and Four-core Switches cannot be switched to light-ON when operating (NC wiring).) Light-ON when Operating 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.

WLRG2-LDS WLRG2-LDS-N WLCA2-LDAS 44 WL-N WL WLRGCA2-LES WL-N WLRGCA2-LES-N WL-N/WLM-N Safety Precautions Precautions for Safe Use • 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. Precautions for Correct Use 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. • 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. Not Suitable Suitable • 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 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. Front Mounting : Four, 5.2 +0.2 0 dia. holes or M5 tapped holes 58.7±0.15 Rear Mounting : Four, 6.2 +0.2 0 dia. holes 30.2 ±0.15 45 WL-N/WLM-N Tightening Torque Overtravel Markers • 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. (1) (3) (6) • 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.

Ex.) V1.25-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. • 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 it’s possible to be destroyed or shorted. • The ground terminal is only installed on models with ground terminals. 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 In the case of prewired connecter and direct connecter • Holding the connecter certainly when pulling connecter. • Don’t pull the cable holding it. • By using the Terminal Plate (sold separately), as shown in the following diagram, the Switch can be used as a single-polarity double-break switch. Attach the Terminal Plate so that the “COM” mark is oriented as shown on the left. 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. 46 Terminal Plate Model WL-N TERMINAL PLATE Terminal Plate Mounting Diagram (with Two Terminal Screws Removed) WL-N/WLM-N 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.) • 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 Correct Dog Dog 64 58.7 Mounting Plate Plate mounting bolts (2) Set contents • Make sure that the actuator does not exceed the OT (overtravel) range, otherwise the Limit Switch may malfunction.

WLN-P001 70% of 100% of rated OT rated OT 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 Correct FP (Free position) OP (Operating position) OT (Overtravel) TTP (Total travel position) Optimum setting range Distance to the optimum setting range. Reference line • 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 Incorrect Stopper Correct • 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 Snapped back Abruptly Correct actuated Operating body • 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 Dog Operating body Correct Dog Others • Unbalanced force must not be imposed on the actuator. Otherwise, wear and tear on the actuator may result. Incorrect Dog Roller Correct • 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 Switch’s performance.
