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 rough-
ening of the contact surface and contact reliability may be lost.
3. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are suffi-
cient 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,
premature wear, Switch damage or malfunctioning may occur.
4. The durability is for an ambient temperature of 5°C to 35°C and an ambient humidity of 40% to 70%. For more details, consult your
OMRON representative.
5. If the ambient temperature is greater than 35°C, do not pass the 3-A, 250-VAC load through more than 2 circuits.
6. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the ac-
tual load beforehand.
7. The mechanical durability of fork lever lock models is 10,000,000 operations min.

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.

Contact Form
Note: 1. Terminals are numbered according to EN50013 and the contact forms are according to IEC947-5-1.
2. 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
Refer to OMRON SAFETY COMPONENTS SERIES (Y106) for
common precautions for Switches and Safety Limit Switches.
Do not use metal connectors or metal conduits with this Switch.
Doing so may occasionally result in electric shock.
Precautions for Safe Use
•Do not drop the Switch . Doing so may result in the Switch not
performing to its full capacity.
•Do not attempt to disassemble or modify the
Switch . Doing so may
cause the Switch to malfunction.
•Do not use the
Switch where explosive gas, flammable gas, or any
other hazardous gas may be present.
• 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.)
•Protect the head from foreign material. Subjecting the head to
foreign material may result in premature wear or damage to the
Switch. Although the switch body is protected from penetration by
dust or water, the head is not protected from penetration by minute
particles or water.
•Turn the power OFF before wiring. Doing so may result in electric
shock.
•Install the cover after wiring. Not doing so may result in electric
shock.
•Connect a fuse to the Switch in series to protect the Switch from
short-circuit damage. Use a fuse with a breaking current 1.5 to 2
times larger than the rated current. To conform to EN ratings, use
an IEC60269-compliant 10-A fuse type gI or gG.
•Do not switch circuits for two or more standard loads (250 VAC,
3 A) at the same time. Doing so may adversely affect insulation
performance.
•The durability of the Switch is greatly affected by operating
conditions. Evaluate the Switch under actual working conditions
before permanent installation and use within a number of switching
operations that will not adversely affect the Switch’s performance.
•Be sure to indicate in the machine manufacturer’s instruction
manual that the user must not attempt to repair or maintain the
Switch and must contact the machine manufacturer for any repairs
or maintenance.
•Check the Switches before use and inspect regularly, replacing
them when necessary. If a Switch is kept pressed for an extended
period of time, the components may deteriorate quickly, and the
Switch may not release.
Precautions for Correct Use
Environment
•The Switch is intended for indoor use only.
•Do not use the Switch outdoors. Doing so may cause the Switch to
malfunction.
•Do not use the Switch where hazardous gases (e.g., H2S, SO2,
NH3, HNO3, CI2) are present or in locations subject to high
temperature and humidity. Doing so may result in damage to the
Switch caused by contact failure or corrosion.
•Do not use the Switch under any of the following conditions.
•Locations subject to extreme temperature changes.
•Locations where high humidity or condensation may occur.
•Locations subject to excessive vibration.
•Locations where metal dust, processing waste, oil, or chemicals
may penetrate through the protective door.
•Locations subject to detergents, thinner, or other solvents.
Mounting Method
Mounting Screw 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 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.
•Secure the Switch with two M4 bolts and washers. Provide studs
with a diameter of 4−0.05/−0.15 and a height of 4.8 mm max. at two
places, inserting into the holes at the bottom of the Switch as
shown below so that the Switch is firmly fixed at four points.
Switch Mounting Holes One-conduit Type
Two-conduit Type
•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.

G-238 Safety Sensors / Components
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. The crimp
terminals shown below are not more than 0.5 mm thick.
J.S.T is a Japanese manufacturer.
Contact Arrangement
•The following diagrams show the contact arrangements used for
screw terminal types and connector types.
Screw Terminal Type
Connector Type
•Applicable socket: XS2F (OMRON).
•Refer to the G010 Connector Catalog for details on socket pin num-
bers 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. Other-
wise, 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.
•When using 1/2-14NPT, wind sealing tape around the joint between
the connector and conduit opening so that the enclosure will con-
form to IP67.
•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.
