wl wl 7 general-purpose models these limit switches are two-circuit double-break switches housed in rugged diecast, thus making it an oil-tight, waterproof and dust- proof construction (complies with ip67). in addition to the standard models, microload models are also avail- able. 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 resist- ant 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 stain- less steel and boasts high resistance to wear. requires maintenance (excessive overtravel) shaft section seal by fitting an o-ring to the rotary shaft and with an appropriate interference of the screws, high-seal- ing properties are maintained. conduit opening (see note 1.) the conduit threads are parallel threads for g 1 / 2 tube and offer further increased sealing properties when used in conjunction with the sc connector. 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 cor- ners of the head. requires maintenance (excessive overtravel) proper range requires maintenance (insufficient overtravel) proper range head-mounting screws bearing the bearing smooths the plunger movement. built-in switch the built-in switch (for all models except the micro- load models) has an extended mechanical life of 15 million operations or more. lever the lever forged of anti-corrosive aluminium alloy features high corrosion resistances and outstand- ing 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 (see note 2.) cover seal by using an o-ring as the cover seal, an optimum squeeze can be obtained and high sealing proper- ties are assured as well. terminal screws m4 screws cover insulator the insulator has outstanding insulation proper- ties and prevents the generation of any gases which may corrode the internal parts. cover setscrew a phillips screw is used to ensure ease of use. note: 1. the display for conduit threads has changed from pf 1 / 2 to g 1 / 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 pos- sible with general-purpose roller lever, adjustable roller lever, and adjustable rod lever models. for the overtravel models, only -2n series models have this function.) ratings type rated l t non-inductive load inductive load y p voltage resistive load lamp load inductive load motor load nc no nc no nc no nc no standard, l 125 vac 10 a 10 a 3a 1.5 a 10 a 5a 2.5 a , overtravel ( e x c e p t 250 vac 10 a 10 a 2a 1a 10 a 3a 1.5 a ( excep t high-sensitivity 500 vac 10 a 10 a 1.5 a 0.8 a 3a 1.5 a 0.8 a h i g h s e n s i t i v i t y models), and h i g h p r e c i s i o n 8vdc 10 a 6a 3a 10 a 6a high-precision models. 14 vdc 10 a 6a 3a 10 a 6a m o d e l s . 30 vdc 6a 4a 3a 6a 4a 125 vdc 0.8 a 0.2 a 0.2 a 0.8 a 0.2 a 250 vdc 0.4 a 0.1 a 0.1 a 0.4 a 0.1 a overtravel ( h i h i i i ) 125 vac 5a --- --- --- (high-sensitivity) 250 vac 5a 125 vdc 0.4 a --- --- --- 250 vdc 0.2 a note: 1. the above figures are for standard currents. 2. inductive loads have a power factor of 0.4 min.

wl wl 39 application variations item appropriate model/actuator details changing the installation position of the actuator by loosening the allen-head bolt on the actuator lever, the position of the actuator can be set anywhere within the 360 _ . 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. roller levers: wlca2, wl01ca2, wlh2, wl01h2, wlg2, wl01g2 adjustable roller levers: wlca12, wl01ca12, wlh12, wl01h12, wlg12, wl01g12 adjustable rod levers: wlcl, wl01cl, wlhl, wl01hl, wlgl, wl01gl loosen the m5 12 bolt, set the actuator?s position and then tighten the bolt again. changing the orientation of the head 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. roller levers: wlca j , wl01ca j , wlgca j adjustable rod levers: wlcl, wl01cl horizontal plungers: wlsd j , wl01sd j roller plungers: wld2, wl01d2 sealed roller plungers: wld28, wl01d28. note: does not include -rp60 series or -141 series. loosen the screws. head loosen the screws. head changing the operating direction 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. the tightening torque for the screws on the head is 0.78 to 0.88 n s m.

wl wl 41 precautions cautions 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. correct use 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 cur- rent, 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 incor- rectly (assembly, tightening torque) can result in malfunction, leak- age current, or fire, so be sure to read the instruction manual thor- oughly 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. environmental precautions when the switch is used in locations subject to splashes of water or oil, the material of the seal, which ensures the sealing properties of the switch, may undergo changes in shape and quality. this is due to deterioration (including expansion and contraction), and may re- sult in reduced performance, ineffective return, and ineffective seal- ing (leading to ineffective contact, insulation, leakage current, and fire). confirm the possible effects of the operating environment on the switch before use. built-in switch 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 in- effective. correct 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 correct torque. no. type torque a head mounting screw 0.78 to 0.88 n s m b cover mounting screw 1.18 to 1.37 n s m c allen-head bolt (for securing the lever) 4.90 to 5.88 n s m d terminal screw 0.59 to 0.78 n s m e connector 1.77 to 2.16 n s m f main unit screws 4.90 to 5.88 n s m in particular, when changing the direction of the head, make sure that all screws are tightened again to the correct torque. do not al- low foreign objects to fall into the switch. installing the switch to install the switch, make a mounting panel, as shown in the follow- ing diagram, and tighten screws using the correct torque. standard/overtravel model overtravel model (side installation) mounting holes four, 5.2 +0.2 0 dia. holes mounting holes two, 5.2 +0.2 0 dia. holes
