For information on applicable models, see pages 26 to 29. 6 WL WL General-purpose Models These Limit Switches are two-circuit double-break switches housed in rugged diecast, thus making it an oil-tight, waterproof and dustproof construction (complies with IP67). In addition to the standard models, microload models are also available. A wide range of actuators with a range of functions are available; rotating lever, plunger, flexible rod etc. The rubber material in the standard models is designed to be resistant to water and most oils. Nomenclature 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 is is between the two main wires on the plunger. Roller The roller is made of self-lubricating sintered stainless steel and boasts high resistance to wear. Head-mounting Screws 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.) Requires maintenance (excessive overtravel) Proper range Requires maintenance (insufficient overtravel) Proper range Requires maintenance (excessive overtravel) Roller Lever Setscrew Operational Plunger (See note 2.) Head The Head used in the roller lever type, adjustable rod lever type, or horizontal plunger type (except the -2N Series) can be mounted in any of the four directions by removing the screws at the four corners of the Head. Cover Seal By using an O-ring as the cover seal, an optimum squeeze can be obtained and high sealing properties are assured as well. 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. Cover Terminal Screws M4 screws Insulator The insulator has outstanding insulation properties and prevents the generation of any gases which may corrode the internal parts. Bearing The bearing smooths the plunger movement. Built-in Switch The built-in switch (for all models except the microload models) has an extended mechanical life of 15 million operations or more. Note: Conduit Opening (See note 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 Setscrew A Phillips screw is 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, three operational directions can be selected electrically. (This is only possible with general-purpose roller lever, adjustable roller lever, and adjustable rod lever models. For the overtravel models, only -2N Series models have this function.)

The overtravel models are classified into three types; general-purpose, high-sensitivity, and models which are capable of one-side 90_ operation, the -2N Series. The -2N Series can also be installed on either side. Since this model is identical to the standard model in dimensions, both models are interchangeable. Like the standard model, it is oil-tight, waterproof, and dustproof (complies with IP67). Overtravel Models (1) Overtravel Models (2) General-purpose, high sensitivity models -2N Series Head can be mounted in any of the four directions. The lever operates on either side at 80_. One-side operation is impossible. The Head can be mounted in two directions, forward and backward. The lever operates on either side at 90_. One side operation is possible.

Nomenclature Double Nut Lever Roller, Roller Axis Using stainless steel prevents spatter from adhering. Allen-head Lever SUS304 is used for double nut. Screws SUS304 is used, preventing spatter from adhering. Operating Lever Melamine sinter-painted, it is easy to peel off the spatter. Head Cap Using Teflon prevents spatter from adhering. Note: Spatter means the Zn powder produced when welding. Adhering spatter to the Limit Switch may cause malfunction of lever or lamp cover. Lamp Cover Heat-resistant resin is used for the lamp cover.

Contact Form (White) (Blue) (Black) (Red) Lamp-equipped Models The operating status of the Switch can be checked using a neon lamp of LED indictor. Circuit checks and troubleshooting errors are easy done. The lamp-equipped models are ideal in locations using a conveyor belt where items need to be checked, or locations that are difficult to inspect for faults. Light-emitting diode (LED) Lamp holder Light-ON when Operating LED at top Contact spring Operation Indictor window The built-in switch’s terminal screws are used to connect the lamp terminal (indicator cover). Since the connection spring (coil spring) is used for this connection, it will not be necessary to connect to the lamp terminal. When a ground terminal is provided however, lead wire method must be used. WL-LD has a built-in rectifier stack, so it will not be necessary to change the polarity. The indicator cover is molded from diecast aluminum and has outstanding sealing properties. Furthermore, regardless of whether the power is connected or not, the operating status is shown (operating or not operating), and indicators can be switched from light-ON when operating and light-ON when not operating, by simply rotating the lamp holder by 180_.

With Lamp-equipped Switches, the actuator lever comes in contact with the top of the lamp cover, so use caution when rotating and setting the lever. When the lever only moves forwards and backwards, it will not contact the lamp cover. Adjustable Roller Levers: WLCA12, WL01CA12, WLH12, WL01H12, WLG12, WL01G12 Changing the orientation of the Head Roller Levers: WLCAj, WL01CAj, WLGCAj By removing the screws in the four corners of the Head, the Head can be set in any of the four directions. Be sure to change the plunger for internal operations at the same time. (The operational plunger does not need to be changed on overtravel general-purpose and high-sensitivity models.) The roller plunger can be set in either two positions at 90_. WLCA2-2N and WL01CA2-2N can only be set in either the forward or backward direction. Adjustable Rod Levers: WLCL, WL01CL Details Loosen the M5 × 12 bolt, set the actuator’s position and then tighten the bolt again.

Changing the operating direction Roller Levers: WLCAj, WL01CAj By removing the Head on models which can operate on one-side only, and then changing the direction of the operational plunger, one of three operating directions can be selected. In the case of overtravel models, as noted on page 20, by loosening the rubber holder using either a coin or a flat-blade screwdriver, and changing the direction of the internal rubber section, one of three operating directions can be selected. Adjustable Roller Levers: WLCA12, WL01CA12 Adjustable Rod Levers: WLCL, WL01CL The output of the Switch will be changed, regardless of which direction the lever is pushed. Operating Operating Not operating The output of the Switch will only be changed when the lever is pushed in one direction.

Loosen this Allen-head bolt and adjust the length of the lever. 40 Adjustment range: 25 to 89 mm Loosen this Allen-head bolt and adjust the length of the rod. WL WL Precautions Cautions Built-in Switch 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. Do not remove or replace the built-in switch. If the position of the built-in switch moves, it can cause reduced performance, and if the insulation sheet moves (separator), the insulation may become ineffective. Correct Use Correct Tightening Torque 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 parallel with the Switch. In order to meet EN approval ratings, use a 10-A fuse that corresponds to IEC269, either a gI or gG. When wiring terminal screws, use M4 round crimp terminals and tighten screws to the recommended torque. Wiring with broken wires, or the 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. 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.

This is due to deterioration (including expansion and contraction), and may result in reduced performance, ineffective return, and ineffective sealing (leading to ineffective contact, insulation, leakage current, and fire). Confirm the possible effects of the operating environment on the Switch before use. 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. Installing the Switch To install the Switch, make a mounting panel, as shown in the following diagram, and tighten screws using the correct torque.

To ensure high-sealing properties, use the SC Connector. (Refer to pages NO TAG to NO TAG.) (SC-1M to -5M and others.) All rotating lever models, except the fork lever lock, have a set position marker plate. (See page 7.) After operation, set the indicator needle on the marker plate so that is in the convex section of the bearing. Wiring Terminal Plate Use 1.25-mm lead wires and M4-insulation covered crimp terminals for wiring. By using a short circuit plate, as shown in the following diagram, the Switch can be fabricated into a single-polarity double-break model.
