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.

Structure and Nomenclature  
Structure  
Safety-oriented Lever Setting  
(Form-lock construction)  
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.  
Conduit Opening  
A wide variety of conduits is available.

Safety Precautions  
Be sure to read the precautions for all D4N models in the website at: http://www.ia.omron.com/.  
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.  
Mounting Method

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.

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.

Do not push crimp terminals into gaps in the case interior. Doing so  
may cause damage or deformation of the case.  
Use crimp terminals not more than 0.5 mm in thickness. Otherwise,  
they will interfere with other components inside the case.

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

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.  
Use the recommended connectors to ensure conformance to IP67.

Use LAPP connectors together with seal packing (JPK-16, GP-13.5,  
or GPM20), and tighten to the specified tightening torque. 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.
