Characteristics
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.

M12 connector
Note: M12 connector types are not available for
Switches with three contacts.
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.
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.
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.

Note: The terminal numbers are according to EN 50013 and the contact symbols are according to EN 60947-5-1.
*MBB (Make Before Break) contacts have an overlapping structure, so that before the normally closed contact (NC) opens, the normally open
contact (NO) closes.

Safety Precautions
Be sure to read the precautions for All Safety Limit Switches in the website at:http://www.ia.omron.com/.
Indication and Meaning for Safe Use
!CAUTION
•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.
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
Tighten each of the screws to the specified torque. Loose screws may
result in malfunction of the Switch within a short time.
Switch Mounting
•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 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.
Switch Mounting Holes
•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.
Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or in property damage.
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, or undesirable effect on product
performance.
Electric shock may occasionally occur.
Do not use metal connectors or metal conduits.

Wiring
Wiring
•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)
Two-conduit Type (3 Poles)
•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.
[Reference] The crimp terminals shown below are not more than
0.5 mm thick.
Contact Arrangement
•The contact arrangements are shown below.
Screw Terminal Type
Connector Type
•Applicable socket: XS2F-D421 series (OMRON).
•Refer to the Connector Catalog for details on socket pin numbers
and lead wire colors.
Socket Tightening (Connector Type)
•Turn the socket connector screws by hand and tighten until no
space remains between the socket and the plug.
•Make sure that the socket connector is tightened securely.
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.

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.
