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 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. 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.

Head
Grooves which engage the lever are cut in the lever and
rotary shaft to prevent the lever from slipping against the
rotary shaft.
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.)
There are resin-lever and metal-lever types.

Safety Precautions
Refer to the “Precautions for All Switches” and “Precautions for All Safety Limit Switches”.
Switch Mounting
• Mount the Switch using M4 screws and spring washers and tighten
the screws to the specified torque.
!CAUTION
Electric shock may occasionally occur.
Do not use metal connectors or metal conduits.
• 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
−0.05
−0.15
a diameter of 4
mm can be provided, the studs inserted into the
Precautions for Safe Use
holes on the bottom of the Switch, and the Switch secured at four
locations to increase the mounting strength.
• 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.

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.

• 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.

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.
• The contact arrangements are shown below.

• 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.

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.

packing is sold separately.
• LAPP is a German manufacturer.
• Before using a 2-conduit 1/2-14NPT type, attach the provided
changing adaptor to the Switch and then connect the
recommended connector.
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.

: The actuator on the D4D-N is a non-safety type. The D4N is recommended for safety applications (form lock type). Be sure to mount it
correctly.
: M screws are recommended to comply with European standards. Therefore, the M20 type is recommended as a substitute when the Pg13.5
conduit-type is not available in a D4N model.

machine, system, or other application or use.
The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles,
safety equipment, and installations subject to separate industry or government regulations.
Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE
SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCTS ARE PROPERLY RATED AND
INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
PROGRAMMABLE PRODUCTS
OMRON shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
Disclaimers
CHANGE IN SPECIFICATIONS
Product specifications and accessories may be changed at any time based on improvements and other reasons.
It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
PERFORMANCE DATA
Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the
result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.
