Weight Approx. 82 g (D4N-1120) Approx. 99 g (D4N-6120) Note: 1. The above values are initial values. 2. Once a contact has been used to switch a standard load, it cannot be used for a load of a smaller capacity. Doing so may result in roughening of the contact surface and contact reliability may be lost. *1. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are sufficient for the operating conditions and environment beforehand. Although the switch box is protected from dust or water penetration, do not use the D4N in places where foreign material such as dust, dirt, oil, water, or chemicals may penetrate through the head. Otherwise, accelerated wear, Switch damage or malfunctioning may occur. *2. The durability is for an ambient temperature of 5 to 35C and an ambient humidity of 40% to 70%. For more details, consult your OMRON representative. *3. Do not pass the 3 A, 250 VAC load through more than 2 circuits. *4. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual load beforehand. *5. The mechanical durability of fork lever lock models is 10,000,000 operations min. 6 D4N Structure and Nomenclature Structure Safety-oriented Lever Setting (Form-lock construction) Grooves which engage the lever are cut in the lever and rotary shaft to prevent the lever from slipping against the rotary shaft. There are resin-lever and metal-lever types. Head The direction of the switch head can be varied to any of the four directions. (Roller plunger models can be mounted in either of two directions at a 90 angle.) Conduit Opening A wide variety of conduits is available. Built-in Switch The built-in switch has a direct opening mechanism that forcibly separates the NC contact even when there is contact deposit. Cover The cover, with a hinge on its lower part, can be opened by removing the screw of the cover, which ensures ease of maintenance and wiring.

Switch Mounting !CAUTION Electric shock may occasionally occur. Do not use metal connectors or metal conduits. Precautions for Safe Use * Do not use the Switch submerged in oil or water, or in locations continuously subject to splashes of oil or water. Doing so may result in oil or water entering the Switch interior. (The IP67 degree of protection specification for the Switch refers to water penetration while the Switch is submersed in water for a specified period of time.) * Always attach the cover after completing wiring and before using the Switch. Also, do not turn ON the Switch with the cover open. Doing so may result in electric shock. * Do not switch circuits for two or more standard loads (250 VAC, 3 A). Doing so may adversely affect insulation performance. * Mount the Switch using M4 screws and spring washers and tighten the screws to the specified torque. * For safety, use screws that cannot be easily removed, or use an equivalent measure to ensure that the Switch is secure. * As shown below, two studs with a maximum height of 4.8 mm and a diameter of 4 -0.05 -0.15 mm can be provided, the studs inserted into the holes on the bottom of the Switch, and the Switch secured at four locations to increase the mounting strength.

Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The contact surfaces will become rough once they have been used and contact reliability for smaller loads may be reduced. 220.1 4-0.05 -0.15 dia. Height: 4.8 max. -0.05 4 -0.15 dia. Height: 4.8 max. * Make sure that the dog contacts the actuator at a right angle. Applying a load to the switch actuator (roller) on a slant may result in deformation or damage of the actuator or rotary shaft. Mounting Method Dog Dog Appropriate Tightening Torque Tighten each of the screws to the specified torque. Loose screws may result in malfunction of the Switch within a short time. 1 Terminal screw 0.6 to 0.8 N*m 2 Cover mounting screw 0.5 to 0.7 N*m 3 Head mounting screw 0.5 to 0.6 N*m 4 Lever mounting screw 1.6 to 1.8 N*m 5 Body mounting screw 0.5 to 0.7 N*m 6 Connector, M12 adaptor 1.8 to 2.2 N*m 7 Cap screw Incorrect Correct 1.3 to 1.7 N*m 3 4 5 1 7 2 6 17 D4N Wiring Wiring Contact Arrangement * When connecting to the terminals via insulating tube and M3.5 crimp terminals, arrange the crimp terminals as shown below so that they do not rise up onto the case or the cover. Applicable lead wire size: AWG20 to AWG18 (0.5 to 0.75 mm2). Use lead wires of an appropriate length, as shown below. Not doing so may result in excess length causing the cover to rise and not fit properly. One-conduit Type (3 Poles) * The contact arrangements are shown below.

Otherwise, the rated degree of protection (IP67) may not be maintained and vibration may loosen the socket connector. Conduit Opening * Connect a recommended connector to the opening of the conduit and tighten the connector to the specified torque. The case may be damaged if an excessive tightening torque is applied. * Use a cable with a suitable diameter for the connector. * Attach and tighten a conduit cap to the unused conduit opening when wiring. Tighten the conduit cap to the specified torque. The conduit cap is provided with the Switch (2-conduit types). Changing the Lever The lever mounting screws can be used to set the lever position to any position in a 360 angle at 7.5 increments. Grooves are incised on the lever and rotary shaft that engage to prevent the lever from slipping against the rotary shaft. The screws on adjustable roller lever models can also loosened to change the length of the lever. Remove the screws from the front of the lever before mounting the lever in reverse (front/back), and set the level so that operation will be completed before exceeding a range of 180 on the horizontal. 18 D4N Recommended Connectors Use connectors with screws not exceeding 9 mm, otherwise the screws will protrude into the case interior, interfering with other components in the case. The connectors listed in the following table have connectors with thread sections not exceeding 9 mm. Use the recommended connectors to ensure conformance to IP67.

Seal packing is sold separately. * LAPP is a German manufacturer. Others * When attaching a cover, be sure that the seal rubber is in place and that there is no foreign material present. If the cover is attached with the seal rubber out of place or if foreign material is stuck to the rubber, a proper seal will not be obtained. * Do not use any screws to connect the cover other than the specified ones. The seal characteristics may be reduced. * Make sure that foreign particles do not enter the head when removing the screws from the four corners to change the head position in any of the four directions. * Use the following recommended countermeasures to prevent telegraphing when using adjustable or long levers. 1. Make the rear edge of the dog smooth with an angle of 15 to 30 or make it in the shape of a quadratic curve. 2. Design the circuit so that no error signal will be generated. 19 Read and Understand This Catalog Please read and understand this catalog before purchasing the products.
