INDICATOR LIGHTING CIRCUIT (Connector type only) 1) See the circuit diagram. 2) The LED only takes 24 DC V, but please use a connector designed for AC. 3) Since the LED lamp is connected to the N.O. side (contact No. 4), please connect the load to contact No. 4. The load side should be on the "+" power supply side. Be careful, because the LED will break if the connection is reversed. 4) The LED is turned on when the switch is at a free position. The LED is turned off when the switch operates. 5) Applicable power source is 24 V DC. Use it with care on leakage current. The leakage current is approx. 1.5 mA at 24 V DC. Confirm the fitting metal is on tightly. If it is loosen, it might be cause of the trouble. Circuit diagram Switch Contact No. 2 Load Contact No. 4 + LED Resistance Contact No. 3 - 31 HL (AZH) CAUTIONS Common for all types 1. There are limits to what type of environment can be tolerated. This limit switch is designed under the premise that it will be used in a standard industrial device. Accordingly, there are limits as to what can be tolerated if used outdoors or where water and oil, etc., may get on the device. The following table indicates how much water and oil can be withstood (classification of protective structure). Plastic case (AZH1*) Die casting case (AZH2*) Protective classification IP64 IP67 Testing method No harmful effect when sprayed with water for 10 minutes from all angles. Water does not enter product after immersion in water 1m deep for 30 minutes. Limits on use Cannot be used outdoors or in a place where water and oil, etc., will continually contact the device. Cannot be used outdoors where it can be rained on directly and cannot be used submersed in water or in oil, etc. Note: Although, initially, the protective classification complies under the testing above, due consideration must be taken because great differences may result depending on factors such as duration of operation, installation method, and environment. 2. The internal mechanism will break if the actuator is moved beyond its Total-travel (T.T.). Always use within the T.T. Die casting case 1) Do not expose HL limit switch to hot water (over 60C 140F) and in a water vapor environment. 2) Avoid the place where organic solvents, strong acid, strong alkali liquid and vapor may attach to the products directly. Prevent using the HL limit switch in place where inflammable or corrosive gas will be generated. 3) Do not change the operating position by bending the actuator. 4) Use within an ambient temperature of -10 to 80C. (However, do not allow it to freeze.) 5) If OT is too big, the life of limit switch will be shortened by switching friction. Use it with enough margin of OT. 70% of OT standard value will be good. 6) Attach the terminal cover securely to the body with the metal stop latch to the projection of the body. 7) Confirmation test in the actual application is highly recommended. 8) Do not use the switch in a silicon atmosphere. Care should be taken where organic silicon rubber, adhesive, seling material, oil, grease or lead wire generates silicon. 9) When used outdoors (in places where there is exposure to direct sunlight or rain such as in multistory car parks) or in environments where ozone is generated, the influence of these environments may cause deterioration of the rubber material. Please consult us if you intend to use a switch in environments such as these. 10) Avoid use in excessively dusty environments where actuator operation would be hindered. Plastic case 1) Do not use in water or oil. Do not place the switch where it is always exposed to water or dust splash. 2) Do not expose HL limit switch to hot water (over 60C 140F) and in a water vapor environment. 3) Avoid the place where organic solvents, strong acid, strong alkali liquid and vapor may attach to the products directly. Prevent using the HL limit switch is place where inflammable or corrosive gas will be generated. 4) Do not change the operating position by bending the actuator. 5) Use within an ambient temperature of -10 to 80C. (However, do not allow it to freeze.) 6) If OT is too big, the life of limit switch will be shortened switching friction. Use it with enough margin of OT. 70% of OT standard value will be good for use. 7) Attach the terminal cover securely to the body to the extent you can identify the clicking or locking sound. 8) A confirmation test in the actual application is highly recommended. 9) Do not use the switch in a silicon atmosphere. Case should be taken where organic silicon rubber, adhesive, sealing material, oil, grease or lead wire generates silicon. 10) When used outdoors (in places where there is exposure to direct sunlight or rain such as in multistory car parks) or in environments where ozone is generated, the influence of these environments may cause deterioration of the rubber material. Please consult us if you intend to use a switch in environments such as these. 11) Avoid use in excessively dusty environments where actuator operation would be hindered. 32 SELECTOR CHART Classification Subminiature size Product name SL (AZ3) Micro Limit Switches Compact size HL (AZH) Limit Switches (Die cast case) HL (AZH) Limit Switches (Die cast case) HL (AZH) Limit Switches (Plastic case) ML (AZ7) Limit Switches (standard) ML (AZ7) Limit Switches (Epoxy-Sealed terminal type) Appearance AZH20 AZH10 22 AZH23 12 AZ7 AZ7 * A limit switch with * Switches installed * An ML compact limit * High sealability that * High sealability that * Bifurcated type available. satisfies IEC IP67. high-density mounting satisfies IEC IP67. with both economical switch with an * Perfect for applicathat improves stroke * Wiring is screw-ter- * Less wiring, less and compact Z-basic epoxy-sealed case tions that prioritize installation conneccapacity through an microswitches and that completely minal type.

Limit switches come under contamination level 3. Pollution degree Contents 1 No contamination or, even if contamination is present, only non-conducting contamination is generated. 2 Normally, only non-conducting contamination is generated, but there remains the possibility of temporary conducting contamination when the circuit is formed. 3 Conducting contamination is generated, or else dry non-conducting contamination is generated by circuits which can be anticipated. 4 Permanent conducting contamination is generated by dust, rain, snow, and other conductors. PROTECTIVE CONSTRUCTION Protective construction Expresses the degree of protective construction that guards the level of functionability of the switch against ingress of solid objects, water, and oil. The standards are IEC529 (IEC: International Electrotechnical Commission) standards. IEC standards determine the level of protection against both water and solid objects, but not against oil. Protection against both water and solid objects IP- Level Protection level 0 Protection level and test methods -- No particular protection Protection against rain fall 3 Rain-proof No damage incurred when sprayed with water continuously for 10 minutes at angles of up to 60 from the perpendicular.

The talcum powder does not penetrate the inside. Note: 1. All of the tests cited above were conducted with the cord vent (conduit vent) tightly shut. 2. The above protective constructions are based on IEC standard but major differences may arise due to length of use and operating environment. This should be thoroughly discussed and verified. 3. When the corrosion-proof model is immersed in water for 30 minutes or more, verify that no water has penetrated the inside before use. 7 CAUTIONS FOR USE DESIGN OF OPERATING DOG AND OPERATING SPEED Pay attention to the following points when designing the dog for limit switch operation. 1. Make the dog faceplate as smooth as possible. 2. Adjust both the dog angle and the set arm angle as below, depending on the operating speed. 3. The depth (h) of the dog effects the lifespan of the limit switch. Therefore, set the depth to a maximum of 80% of the Total Travel (T.T.) 4. The relationship between the speed of the dog (V = m/s) and the tip angle () is as follows: 1) V&0.2m/s = 45 to 90 V h 5) Roller plunger type 3) 0.5m/s ! V&2m/s V h F o Vmax (m/s) 40 0.7 35 0.9 30 1.3 25 2.0 The maximum tolerable speed can be extended by further reducing the dog rise angle from 45 when 0.5m/s ! V&2m/s. It is necessary to set the arm so that the dog's cutting surfaces are always parallel ( o = 90- ) 4) Overriding the dog (V&0.2m/s) Vmax (m/s) 45 0.2 60 0.1 60 to 90 0.05 When V&0.2m/s, set the arm to perpendicular and set the arm rise angle to between 45 and 90. If the dog rise angle is reduced, the maximum tolerable speed is increased. As a rule, = 45 is optimum. 2) V&0.5m/s = 45 V h F o = 45 Because the arm jiggle is as a minimum at a comparative speed such as V&0.5m/s, setting both the dog angle so that it travels perpendicularly and the arm angle to 45 is optimum. 8 h h Vmax (m/s) 45 0.2 60 0.1 60 to 90 0.05 If overriding the dog, set the arm perpendicularly, so that =45. If the dog angle is reduced, the tolerable speed is increased. Vmax (m/s) h 20 0.5 (0.5 to 0.7) T.T. 30 0.25 (0.6 to 0.8) T.T. Even if overriding the dog, set the forwards and rearwards motion exactly the same, and avoid any settings that make the actuator accelerate rapidly from the dog. 5. Operation speed 1) When the operation (acting and reverting) speed is exceedingly slow, switching of the contacts will become unstable and this could cause problems such as failure to make contact and welding. As a guide, the speed should be at least 1mm/s. 2) When the operation (acting and reverting) speed is exceedingly fast, be careful because the violent motion could cause breakage and with increased frequency, contact switching will not be able to keep up. As a guide, the switching frequency should be within 20 times per minute. CAUTIONS FOR USE PROTECTION CIRCUIT 2. Do not connect either irregular poles or power sources to a switch contact. Power connection examples (irregular pole connection) 3. Avoid circuits where power may find a way between the contact points (as this may cause welding.) NO GOOD NO GOOD Load L ~ 1. The ON/OFF circuit for the guidance load may suffer contact damage due to surges or inrushes when the power is turned either ON or OFF. Consequently, insertion of a protective circuit as per the following diagram is recommended, in order to protect the contacts. Cautions for use Limit switch contact r c R Limit switch contact r c R (1) r must be a minimum of 10; (2) When using AC power: Q Impossible when R impedance is large. W Possible when c, r impedance is sufficiently small compared with R impedance. Can be used with both AC and DC as appropriate. r~R C: 0.1 F Load Load GOOD L Load Load connected to same pole Example of unsuitable power connection (abnormal power connection) Risk of AC and DC being mixed. Load NO GOOD L AC R (1) Dedicated DC use. (2) AC is impossible DC Limit switch contact ZNR Varistor R Can be used with both AC and DC as appropriate. 200V 100V Limit switch contact Diode ~ L Circuit Load 4. Using electronic switch circuits (low power, low current) 1) Bouncing and chattering are generated due to collision between the contacts when the limit switch is switching between them, and this sometimes causes such problems as white noises and error pulses in both the electronic circuit and the reverberation equipment. 2) If the generation of bouncing and chattering becomes a problem, it is necessary to consider installing a CR circuit or other absorption circuit given the circuit design. 3) This is particularly necessary when high contact reliability is needed, and is unsuitable for silver contact switches. Switches with gold contacts possess excellent performance. L 9 CAUTIONS FOR USE CAUTIONS FOR USE 1) Do not attempt to physically alter any part of the switch itself, such as the actuator, or switch attachment vent, as this may cause alterations to both characteristics and performance, and damage the insulation. 2) Do not pour any lubricants such as oil or grease onto the moving parts of the actuator, as there is a possibility that this will cause a malfunction due to seepage into the inside, and impair the motion. Silicon-based grease in particular affects the contact points badly. 3) If the switches are not to be used for an extended period of time, their contact reliability may be reduced due to oxidation of the contact points. Because accidents may result from the impaired conductivity, always implement a check beforehand. 4) Prolonged continuous use of the switch hastens deterioration of the parts (especially the seal rubber) and may cause a malfunction in the release. For this reason, always implement a check beforehand. 5) Usage in the vicinity of either the switch operating position (O.P.) or the release position (R.P.) results in unstable contacts. If using the NC contact point, set the actuator to return to the free position (F.P.) Also, is using the NO contact point, hold the ratings values down to 70 to 100% for the overtravel (O.T.) 6) If the actuator is forced beyond its total travel (T.T.), the internal mechanism may be damaged. Always use within the T.T. 7) Do not apply unreasonable force to the actuator, as this may result in damage and impaired movement. 8) The switch, if dropped, may break due to excessive vibration and impact. Therefore, please use extra caution when transporting and installing. 9) Condensation inside the switch may occur if there are rapid ambient temperature changes when the switch is in a high temperature and humidity. Since this occurs easily during marine transport, be extra cautious of what the environment will be when shipping. Condensation is the phenomenon in which water vapor condenses into switch-adhering water droplets when the temperature rapidly drops in a high-temperature, high-humidity atmosphere or when the switch is quickly moved from a low temperature location to a place of high temperature and high humidity. It is the cause of insulation deterioration and of rust. 10) Be careful of freezing in temperatures below 0C. Freezing is the phenomenon in which moisture adhering to the switch from condensation or when in unusually high-humidity environments freezes onto the switch when the temperature drops below the freezing point. Please extra caution because freezing can lock moving parts, cause operational delays, or interfere with conductivity when there is ice between the contacts. 11) In low-temperature, low-humidity conditions, plastic becomes brittle and the rubber and grease harden, which may lead to malfunction. 12) Long term storage (including during transport) in high temperature or high humidity environments or where the atmosphere contains organic or sulfide gas, will cause sulfide or oxide membrane to form on the contact surfaces. This in turn will cause unstable or failed contacting that may lead to functional malfunction. Please verify the atmosphere when storing and transporting. 13) Packaging should be designed to reduce as much as possible the potential influence of humidity, organic gas, and sulfide gas, etc. 14) Please avoid sudden changes in temperature. This is a cause of switch deformation and encourages the seal structure to breathe, which may lead to seal failure and operational malfunction. 15) If installing a thermoplastic resin case, the use of a spring washer tightened directly against the case will cause the case to collapse and become damaged. Therefore, please add a flat washer before tightening. Also, be careful not to install if the case is being twisted. 16) For the purpose of improving quality, materials and internal structure may be changed without notice. 17) When used outdoors (in places where there is exposure to direct sunlight or rain such as in multistory car parks) or in ambient temperature environments where ozone is generated, the influence of these environments may cause deterioration of the rubber material. Please consult us if you intend to use a switch in such environments. PRECAUTIONS RELATING TO THE INSTALLATION ENVIRONMENT Avoid using in silicon environments such as organic silicon-based rubber, solvents, sealants, oil, grease, or wiring. 10 IMPROVEMENT EXAMPLES Poor design Improved design Explanation @ r Problem * Dog adjustment is difficult.

Europe IEC standard EN standard International Electrotechnical Commission By promoting international cooperation toward all problems and related issues regarding standardization in the electrical and electronic technology fields, the IEC, a non-governmental organization, was started in October, 1908, for the purpose of realizing mutual understanding on an international level. To this end, the IEC standard was enacted for the purpose of promoting international standardization. 2. North America LISTING MARK Fig. 1 RECOGNITION MARK Fig. 2 Certification Fig. 3 Component Acceptance Fig. 4 Fig. 5 Fig. 6 78 UL (Underwiters Laboratories Inc.) This is a non-profit testing organization formed in 1894 by a coalition of U.S. fire insurance firms, which tests and approves industrial products (finished products). When electrical products are marketed in the U.S., UL approval is mandated in many states, by state law and city ordinances. In order to obtain UL approval, the principal parts contained in industrial products must also be ULapproved parts. UL approval is divided into two general types. One is called "listing" (Fig. 1), and applies to industrial products (finished products). Under this type of approval, products must be approved unconditionally. The other type is called "recognition" (Fig. 2), and is a conditional approval which applies to parts and materials. CSA (Canadian Standards Association) This was established in 1919 as a non-profit, nongovernmental organization aimed at promoting standards. It sets standards for industrial products, parts, and materials, and has the authority to judge electrical products to determine whether they conform to those standards. The CSA is the ultimate authority in the eyes of both the government and the people in terms of credibility and respect. Almost all states and provinces in Canada require CSA approval by law, in order to sell electrical products. As a result, electrical products exported from Japan to Canada are not approved under Canadian laws unless they have received CSA approval and display the CSA mark. Approval is called "certification", and products and parts which have been approved are called "certified equipment", and display the mark shown in Fig. 3. The mark shown in Fig. 4 is called the "Component Acceptance" mark, and indicates conditional approval which is applicable to parts. The C-UL mark shown in Fig. 5 (finished products) and Fig. 6 (parts) indicates that the product has been tested and approved in UL laboratories, based on UL and CSA standards, through mutual approval activities. European Standards/Norme Europeennee (France)/Europaishe Norm (Germany) Abbreviation for European Standards. A unified standard enacted by CEN/CENELEC (European Standards Committee/European Electrical Standards Committee). EU and EFTA member nations employ the content of the EN standards into their own national standards and are obligated to abolish those national standards that do not agree with the EN standards. (1) Germany VDE TUV Rheinland VDE (Verband Deutscher Elektrotechniker) The VDE laboratory was established mainly by the German Electric Technology Alliance, which was formed in 1893. It carries out safety experiments and passes approval for electrical devices and parts. Although VDE certification is not enforced under German law, punishment is severe should electrical shock or fire occur; therefore, it is, in fact, like an enforcement. TUV (Technischer Uberwachungs-Verein) TUV is a civilian, non-profit, independent organization that has its roots in the German Boiler Surveillance Association, which was started in 1875 for the purpose of preventing boiler accidents. A major characteristic of TUV is that it exists as a combination of 14 independent organizations (TUV Rheinland, TUV Bayern, etc.) throughout Germany. TUV carries out inspection on a wide variety of industrial devices and equipment, and has been entrusted to handle electrical products, as well, by the government. TUV inspection and certification is based mainly on the VDE standard. TUV certification can be obtained from any of the 14 TUVs throughout Germany and has the same effectiveness as obtaining VDE certification.

Moreover, the HL limit switch alone does not display the CE mark as standard. If the CE mark is necessary, add (CE) to the end of the part No. when ordering. What are EN standards? An abbreviation of Norme Europeenne (in French), and called European Standards in English. Approval is by vote among the CEN/CENELEC member countries, and is a unified standards limited to EU member countries, but the contents conform to the international ISO/IEC standards. If the relevant EN standard does not exist, it is necessary to obtain approval based on the relevant IEC standard or, if the relevant IEC standard does not exist, the relevant standard from each country, such as VDE, BS, SEMKO, and so forth. CE markings and EC directives The world's largest single market, the European Community (EC) was born on 1 January 1993 (changing its name to EU in November 1993. It is now always expressed as EU, apart from EC directives.) EU member country products have always had their quality and safety guaranteed according to the individual standards of each member country. However, the standards of each country being different prevented the free flow of goods within the EU. For this reason, in order to eliminate non-tariff barriers due to these standards, and to maximize the merits of EU unification, the EC directives were issued concomitant to the birth of the EU. The EN standards were established as universal EU standards in order to facilitate EU directives. These standards were merged with the international IEC standards and henceforth reflect the standards in all countries. Also, the CE markings show that products conform to EC directives, and guarantee the free flow of products within the EC. Appropriate EC directives for control equipment products The main EC directives that are to do with machinery and electrical equipment are the machinery directive, the EMC directive, the low voltage directive, and the telecom directive. Although these directives have already been issued, the date of their enactment is different for each one. The machinery directive was 1 January 1995. The EMC directive was 1 January 1996, and the low voltage directive was enacted from 1 January 1997. The telecom directive was established by the separate CTR (Common Technology references.) 79
