Note: 1. The above values are initial values. 2. The Switch contacts can be used with either standard loads or microloads. 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. *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 D4NS in places where foreign material may enter through the key hole on the head, otherwise Switch damage or malfunctioning may occur. *2. The durability is for an ambient temperature of 5 to 35°C 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. These figures are minimum requirements for safe operation. *5. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual load beforehand.

Refer to the “Precautions for All Switches” and “Precautions for All Safety Door Switches”. !CAUTION

  • Do not use the Switch submersed 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. (The IP67 degree of protection of the Switch specifies the amount of water penetration after the Switch is submerged in water for a certain 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. Stopper Installation Do not use a Switch as a stopper. Be sure to install a stopper as shown in the following illustration to ensure that the base of the Operation Key does not strike the Head, and adjust the stopper to be within the setting zone (0.5 to 3 mm) of the base of the Operation Key. Do not subject the Switch to a shock that exceeds the Switch's shock resistance of 1,000 m/s The Switch contacts can be used with either standard loads or microloads. 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. Mounting Method Appropriate Tightening Torque
  • Loose screws may result in malfunction. Tighten the screws to the specified torques.
  • When loosening a screw with an electrical screwdriver or similar tool while pressing down on the screw head, do not continue turning the screw past the point where the threads disengage. Doing so may strip the end of the threads. Mounting Holes
  • Use M4 screws and spring washers to mount the Switch and Operation Key, and tighten the screws to a suitable torque. To ensure safety, use screws that cannot be easily removed or another means to prevent the Switch and Operation Key from easily being removed.
  • As shown below, two studs with a maximum height of 4.8 mm and a diameter of 4 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.
  • Set the Operation Key so that it is within 1 mm of the center of the key hole. If the Operation Key is offset or at an angle, accelerated wear or breaking may result.
  • Observe the specified insertion radius for the Operation Key and insert it in a direction perpendicular to the key hole. Head Direction
  • The rotation of the Switch head may be adjusted to any of the four directions by loosening the head mounting screws at the four corners of the head. Make sure that no foreign materials enter through the head.
  • Do not insert or remove the Operation Key with the Switch head removed. Doing so may make it impossible to insert the Operation Key. Securing the Door When the door is closed (with the Operation Key inserted), the Operation Key may exceed the set zone because of, for example, the door's own weight, machine vibration, or the door cushion rubber. Secure the door with a stopper so that the Operation Key remains within the set zone. Electric shock may occasionally occur. Do not use metal connectors or metal conduits.

  • When connecting with insulation tubes and M3.5 crimp terminals, connect the terminals as shown in the following figure and wire without overriding to the case and the cover. Adequate conductor size is AWG 20 to AWG18 (0.5 to 0.75 mm2). Prepare lead wires using the lengths given in the following diagrams. If lead wires are too long, they will press against the cover causing the cover to not close properly.
  • Do not push the crimp terminal and the likes into the opening between the parts to prevent the case from being broken and deformed.
  • Use terminals having the thickness of 0.5 mm or less to avoid the contact between the terminal and the Switch case inside. <Reference> The crimp terminals listed below have a thickness of 0.5 mm or less. J.S.T is a Japanese manufacturer. Pin arrangement of connector type
  • Suitable socket is XS2F-D421 series (OMRON).
  • Refer to the Connector Catalog for corresponding Socket pin numbers and lead wire colors. Socket Tightening (Models with Connectors)
  • Turn the tightening screws on the Socket by hand and tighten them until the gap between the Socket and Plug essentially disappears.
  • Make sure that the Socket’s connector is tightened securely, otherwise the rated degree of protection (IP67) of the D4NS may not be maintained, or the Socket connector may be loosened by vibration. Conduit Opening
  • Use cables with suitable diameters for the connector being used.
  • When wiring, place the enclosed cap screw on unused conduit openings (for 2-Conduit Switches) and tighten them to the suitable tightening torque. Recommended Connectors Use the connector with thread section of 9 mm long or less. If a connector with a longer thread section is used, the protruding part may interfere with the other parts inside the body. Use the connectors listed below to ensure IP67 degree of protection. When use LAPP's products, use together with a Seal Packing which is sold separately (Type names, JPK-16, GP-13.5, or GPM20) and tighten with proper tightening torque.
