Warning Indications Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. Precautions for Correct Use Supplementary comments on what to do or avoid doing, to prevent failure to operate, malfunction or undesirable effect on product performance. Precautions for Safe Use • Protective structure Do not use the product with degrade protective structure such as swelling and crack in housing and/or sealing components. Otherwise cutting oil or other substance may enter the product, resulting in a risk of corruption or burning. • Do not disassemble or remodel the switch in any case, or the switch will not operate normally. • The durability of the Switch greatly varies with switching conditions. Before using the Switch, be sure to test the Switch under actual conditions. Make sure that the number of switching operations is within the permissible range. • If an actuator is kept pressed for an extended period of time, the actuator will deteriorate quickly and faulty reset of the Switch may occur. Check the Switch periodically and replace it when necessary. Precautions for Correct Use • The following conditions shall be observed if you use the product under an environment using cutting oil that may affect product's life and/or performance. • Usage under the cutting oil condition designated by the specification • Usage under the cutting oil dilution ration recommended by its manufacturer • Usage in oil or water is prohibited Impact on the product life may differ depending on the oil you use. Before using the cutting oil, make sure that it should not cause deterioration or degradation of sealing components. • The D4ER-@@@@N-DTK1EJ can be used in conditions of cutting oil use described in the specifications. The oil resistance may not be ensured when the products are not mated to XS5@R Connectors, so use the products correctly. • When mating the products to XS2 or other M12 Connectors, tighten the lock to a torque of 0.39 to 0.49 N-m. • To protect the Switch from damage due to short-circuits, be sure to connect a quick-response fuse with a breaking current 1.5 to 2 times larger than the rated current in series with the Switch. • Do not connect lead wires directly to the terminals. Use crimp terminals and attached them securely. • The switch is intended for indoor use only. Do not use the switch outdoor, or the switch will malfunction. • Do not use the switch in the atmosphere of hazardous gases (H2S, SO2, NH3, HNO3, Cl2, etc.) or high temperature and humidity, or it will cause the imperfect closing of the contacts or the breakage thereof stemming from corrosion. • When storing the Switch, do not subject it to hazardous gases (H2S, SO2, NH3, HNO3, Cl2, etc.), dust, dirt, high temperature, or high humidity. • Do not use the switch under any of the conditions mentioned below. • Locations subject to severe temperature changes • Locations where the interior of a protective door may come into direct contact with cutting chips, metal filings, or chemicals • Locations subject to high humidity or condensation • Locations subject to severe vibration • Locations subject to detergents, thinners, or other solvents • Locations where flammable or explosive gases are present • If the Switch is not turned ON and OFF for an extended period of time, contact oxidation may reduce the contact reliability. Continuity failure may result in an accident. • Do not drop the Switch. Doing so may prevent it from functioning to its full capacity. • Do not place an excessive load on the Switch. • Be sure to keep the load current less than the rated value. • Do not supply electric power when wiring. Otherwise electric shock may result. • Setting the stroke close to the operating position (OP) or releasing position (RP) will cause unstable contact. If the full stroke is set to the total travel position (TTP), the actuator or Switch may be damaged due to the inertia of the dog. Therefore, adjust the stroke with the mounting panel or the dog. • The body of the Switch is protected from the ingress of dirt, water, and other foreign matter, but the head is not protected from water or fine foreign matter. You must take measures to prevent water and fine foreign matter from entering the head. Not providing sufficient protection may result in accelerated wear or damage. • Perform inspections and tests to confirm the operating characteristics, insulation resistance, dielectric strength, and contact resistance of the Switch if it is left in a location that does not meet the storage conditions, if it is subjected to condensation, if it is dropped, or if it is stored for more than one year. • The user of the system must not attempt to perform maintenance and repairs. Contact the manufacturer of the system concerning maintenance and repairs. 11 D4ER-@N • Make sure that the dog does not strike the actuator of the Switch at an angle. If a load is placed on the actuator at an angle, the actuator may be deformed or damaged or the rotary shaft may be deformed or damaged. • Do not normally leave the Switch in oil or water. Water or oil may enter the Switch. • Perform scheduled, periodic inspections. Handling • Be sure to connect a fuse with a breaking current 1.5 to 2 times the rated current to the Limit Switch in series in order to protect the Limit Switch from damage due to short-circuiting. When using the Limit Switch under the EN ratings, use a gI or gG 10-A fuse that conforms to IEC 60269. Mounting • Use M4 screws to mount the Switch. Use washers or other means to prevent the screws from becoming loose and tighten the screws to a torque of 1.18 to 1.37 N·m. Mounting Holes Two, 4.3 dia. or M4 holes 33 ±0.15 Mounting pitch • When mounting the panel mount-type Switch with screws on a side surface, remove the hexagonal nuts from the actuator. • When mounting the panel mount type on a panel, tighten the hexagonal nuts of the actuator to a torque less than 7.85 N·m. The two nuts can be attached at the top or bottom and from either side. Mounting Hole 14.5±0.2 dia. • Operating method, shape of cam or dog, operating frequency, and the overtravel (OT) have significant effect on the service life and precision of the Limit Switch. Make sure that the shape of the cam or dog is smooth enough. • If the Limit Switch is used in a normally open condition (NO), sufficiently press the actuator to 70% to 100% of the value specified for the OT. • Do not change the operating position by remodeling the actuator. • Do not bend the cable to a radius that is smaller than 25 mm. 12 OMRON AUTOMATION AMERICAS HEADQUARTERS • Chicago, IL USA • 847.843.7900 • 800.556.6766 • www.omron247.com OMRON CANADA, INC. • HEAD OFFICE Toronto, ON, Canada • 416.286.6465 • 866.986.6766 • www.omron247.com OMRON ARGENTINA • SALES OFFICE Cono Sur • 54.11.4783.5300 OMRON ELECTRONICS DE MEXICO • HEAD OFFICE México DF • 52.55.59.01.43.00 • 01-800-226-6766 • mela@omron.com OMRON CHILE • SALES OFFICE Santiago • 56.9.9917.3920 OMRON ELECTRONICS DE MEXICO • SALES OFFICE Apodaca, N.L. • 52.81.11.56.99.20 • 01-800-226-6766 • mela@omron.com OTHER OMRON LATIN AMERICA SALES 54.11.4783.5300 OMRON ELETRÔNICA DO BRASIL LTDA • HEAD OFFICE São Paulo, SP, Brasil • 55.11.2101.6300 • www.omron.com.br OMRON EUROPE B.V. • Wegalaan 67-69, NL-2132 JD, Hoofddorp, The Netherlands. • +31 (0) 23 568 13 00 • www.industrial.omron.eu Controllers & I/O • Machine Automation Controllers (MAC) • Motion Controllers • Programmable Logic Controllers (PLC) • Temperature Controllers • Remote I/O Authorized Distributor: Robotics • Industrial Robots • Mobile Robots Operator Interfaces • Human Machine Interface (HMI) Motion & Drives • Machine Automation Controllers (MAC) • Motion Controllers • Servo Systems • Frequency Inverters Vision, Measurement & Identification • Vision Sensors & Systems • Measurement Sensors • Auto Identification Systems Sensing • Photoelectric Sensors • Fiber-Optic Sensors • Proximity Sensors • Rotary Encoders • Ultrasonic Sensors Safety • Safety Light Curtains • Safety Laser Scanners • Programmable Safety Systems • Safety Mats and Edges • Safety Door Switches • Emergency Stop Devices • Safety Switches & Operator Controls • Safety Monitoring/Force-guided Relays Control Components • Power Supplies • Timers • Counters • Programmable Relays • Digital Panel Meters • Monitoring Products Switches & Relays • Limit Switches • Pushbutton Switches • Electromechanical Relays • Solid State Relays Software • Programming & Configuration • Runtime C425I-E-01 03/17 Note: Specifications are subject to change. © 2017 Omron.
