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 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.

Shaft Section Seal By fitting an O-ring to the rotary shaft and with an appropriate interference of the screws, high-sealing properties are maintained. Actuator Roller The roller is made of self-lubricating sintered stainless steel and boasts high resistance to wear. Lever The lever forged of anti-corrosive aluminium alloy features high corrosion resistances and outstanding ruggedness. 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.) Roller Lever Setscrew Operational Plunger *2 Bearing The bearing smooths the plunger movement. Built-in Switch Built-in switch with SPST-NO+NC contact form. Set Position Marker Plate After operation, set the indicator needle on the marker plate so that is in the convex section of the bearing. For the WLD2, insert the needle so that it is between the two main wires on the plunger. Requires maintenance (excessive overtravel) Proper range Requires maintenance (insufficient overtravel) Proper range Requires maintenance (excessive overtravel) Terminal Screws Four, M4 screws Separator The separator has outstanding insulation properties and prevents the generation of any gases which may corrode the internal parts. Conduit Opening *1 The conduit threads are parallel threads for G1/2 tube and offer further increased sealing properties when used in conjunction with the SC connector. Cover Seal By using a packing seal as the cover seal, an optimum squeeze can be obtained and high sealing properties are assured as well. Cover Cover Setscrew Phillips screws are used to ensure ease of use. *1. The display for conduit threads has changed from PF1/2 to G1/2, according to revisions of JIS B 0202. This is only a change in the display, so the thread size and pitch have not changed. (Conduit threads Pg 13.5 and 1/2-14NPT are also available.) *2. By changing the orientation of the operational plunger, any one of the three operational directions (both sides, left, or right) can be selected electrically. 23 WL/WLM 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. Models with LED indicators have a built-in rectifier stack, so it is not necessary to change the polarity. Indicator Windows Operation (i.e., light-ON when operating or light-ON when not operating) depends on whether a neon lamp or LED is used. Contact Spring 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. 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. (Molded terminals cannot be switched in this way.)

Please check the load's OFF current before use the indicator-equipped switch. *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. 24 WL/WLM Environment-resistant Switches Mold Specifications for Hermetic Seal Switches WL@-139 : Molded parts WL@-140 WL@-141 Oil seal for protection against cutting powder X-ring Standard built-in switch WL@-145 Airtight built-in switch WL@-RP40 Oil seal for protection against cutting powder X-ring Airtight built-in switch WL@-RP60 O-ring Airtight built-in switch Airtight built-in switch Airtight built-in switch * Florine rubber is used for all rubber parts.

Spatter-prevention Switches: WLCA2-LEAS Actuator Roller, Roller Axis Using stainless steel prevents spatter from adhering. Operating Lever Melamine sinter-painted, it is easy to peel off the spatter. Double Nut SUS is used for double nut. Lamp Cover * Heat-resistant resin is used for the lamp cover. * By using spherical surface for the display part, it disperses the direction of spatter. Screws SUS is used, preventing spatter from adhering. Head Cap Using fluororesin prevents spatter from adhering. * Spatter means the zinc powder produced when welding. Adhering spatter to the Limit Switch may cause malfunction of lever or lamp cover. The lack of gap prevents spatter powder from clogging. 25 WL/WLM Long-life Switches: WLMGCA2-LD Release Plunger Set Position Marker Plate The set position is easy to view.

Unless otherwise indicated, a tolerance of 0.4 mm applies to all dimensions. 2. When using the adjustable roller (rod) lever, make sure that the lever is facing downwards. Use caution, as telegraphing (the Switch turns ON and OFF repeatedly due to inertia) may occur. 38 WL/WLM Safety Precautions Refer to Safety Precautions for All Limit Switches. * When a rod or wired-type actuator is used, do not touch the top end of the actuator. Doing so may result in injury. (Applicable models) WLHAL5 and WL01HAL5 Rod Spring Levers and WLNJ-S2 and WL01NJ-S2 Steel-wire Actuators. * A short-circuit may cause damage to the Switch, so insert a circuit breaker fuse, of 1.5 to 2 times the rated current, in series with the Switch. * In order to meet EN approval ratings, use a 10-A fuse that corresponds to IEC60269, either a gI or gG for general-purpose types and spatter-prevention models only. Precautions for Correct Use * When wiring terminal screws, use M4 round crimp terminals and tighten screws to the recommended torque. Wiring with bare wires, or incorrect crimp terminals, or not tightening screws to the recommended torque can lead to short-circuits, leakage current, and fire. * When performing internal wiring there is a chance of short-circuit, leakage current, or fire, so be sure to protect the inside of the Switch from splashes of oil or water, corrosive gases, and cutting powder. * 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 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. Using Switches for Micro Loads Contact faults may occur if a Switch for a general-load is used to switch a micro load circuit. Use switches in the ranges shown in the diagram below. However, even when using micro load models within the operating range shown here, if inrush current occurs when the contact is opened or closed, it may increase contact wear and so decrease durability. Therefore, insert a contact protection circuit where necessary. The minimum applicable load is the N-level reference value. This value indicates the malfunction reference level for the reliability level of 60% (60). The equation, 60 = 0.5 x 10-6/operations indicates that the estimated malfunction rate is less than 1/2,000,000 operations with a reliability level of 60%. Voltage (V) Precautions for Safe Use 5 mW 800 mW 0.16 mA 30 26 mA 24 Operating range for micro-load models Operating range for standard models 12 Unusable range 5 1 mA 100 mA 160 mA 0 0.1 1 10 100 1,000 Current (mA) Operating Environment * 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. 39 WL/WLM Built-in Switch Connectors Do not remove or replace the built-in switch. If the position of the builtin switch moves, it can cause reduced performance, and if the insulation sheet moves (separator), the insulation may become ineffective. Either the easy-to-use Allen-head nut or the SC Connector can be used as connectors. To ensure high-sealing properties, use the SC Connector. Refer to Limit Switch Connectors for details on SC Connectors. Tightening Torque Wiring * 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. * Use 1.25-mm2 lead wires and M4-insulation covered crimp terminals for wiring.

Rotating Lever Set Position (General-purpose or Spatterprevention Switches Only) Installing the Switch To install the Switch, make a mounting panel, as shown in the following diagram, and tighten screws using the correct torque. Mounting Mounting Mounting locations WL All rotating lever models, except the fork lever lock models, have a set position marker plate. (See page 23.) After operation, set the indicator needle on the marker plate so that is in the convex section of the bearing. Operation Set Position (Long-life Switches Only) For all Long-life Switching, there is a set position marker slit on the rubber cap of the head. After operation, set the slit on the rubber cap so that the fluorescent color on the shaft section can be seen.
