Characteristics
Note: 1. The values in the table on the previous page 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 D4NH 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. For safe use, make sure that the allowable operating speed is not exceeded.
7. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the ac-
tual load beforehand.

tacts
When
opening
the guard
When the guard is opened, the cam that is directly coupled to
the shaft rotates to press the Switch in the direction shown by
the (vertical) arrow. This action separates the contacts to stop
the machine.
The built-in switch has a direct opening mechanism
that forcibly separates the NC contact even when
there is contact deposit.
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.
* The housing and head of the D4NH are made of resin. Use D4BS Miniature
Electromagnetic Lock Safety Door Limit Switches for applications requiring
safety door switches of tough, high-sealing, or oil-resistant construction.
A wide variety of conduits is available.
The arm lever is mounted upwards in the center
position before shipping. To change the position,
loosen the arm lever mounting screw, dismount
the arm lever, and mount the arm lever in the left
or right position.
Cam
The joint between the shaft and
arm lever is formed with form-
lock construction which remains
secure even when the
screw becomes loose.

G-214 Safety Sensors / Components
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.
•Install the Switch in a location away from close body contact. Not
doing so may result in malfunction.
• 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 a 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.
•If the Switch is to be used in an emergency stop circuit or in a
safety circuit for preventing accidents resulting in injuries or deaths,
use a model that has an NC contact equipped with a direct opening
mechanism and make sure that the Switch operates in the direct
opening mode.
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
•Mount the shaft or arm lever securely with a one-way screw, or an
equivalent so that the shaft or arm lever cannot be easily removed.
•Align the rotational center of the shaft with the door, so that the
switch shaft and head will not be subjected to mechanical stress
when the door opens or closes.
Do not impose a force of 50 N or more on the shaft.
Be sure that the arm lever and door are mounted as shown in the fol-
lowing diagram so that the arm lever and head are not subjected to
mechanical stress when the door opens or closes.

Changing the Head Direction
By removing the four screws of the head, the mounting direction of
the head can be changed. The head can be mounted in four direc-
tions. Be sure that no foreign material will enter the head during a
change in direction.
Arm Lever Mounting Position
The arm lever is mounted upwards in the center position before ship-
ping. To change the position, loosen the arm lever mounting screw,
dismount the arm lever, and mount the arm lever in the left or right
position.
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).

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,
GPM20, or GPM12), and tighten to the specified tightening torque.
Seal packing is sold separately.
LAPP is a German manufacturer. Ohm Denki is a Japanese
manufacturer.
Before using an M12 type, attaching the provided changing adaptor
to the Switch and then connect the recommended connector.
Before using a 2-conduit 1/2-14NPT type, attach the provided
changing adaptor to the Switch and then connect the recommended
connector.
Storage
Do not store the Switch in locations where hazardous gases (e.g.,
H2S, SO2, NH3, HNO3, Cl2) or dust is present, or in locations subject
to high temperatures and humidity.
Others
•Do not allow the load current to exceed the rated value.
•Confirm that the seal rubber has no defects before use.
If the seal rubber is displaced or raised, or has foreign particles
adhered to it, the sealing capability of the seal rubber will be
adversely affected.
•Use the correct cover mounting screws only, or the sealing
capability of the seal rubber will deteriorate.
•Inspect the Switch regularly.
•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.
3. Use or set a Switch that is operated in one direction only.
Production Termination
Following the release of the D4NH, production of the D4DH will be
terminated.
Date of Production Termination
Production of the D4DH Series will be terminated in March 2006.
Product Replacement
1. Dimensions
The D4DH and D4NH use the same mounting method, and
mounting hole. The multi-contact structure and the extra 4 mm in
length, however, are different.
2. Terminal Numbers
For the 2-contact model, the terminals 21, 22, 23, and 24 on the
D4DH are 31, 32, 33, and 34 on the D4NH.
3. Recommended Terminals
If the recommended terminals are not used, the Switch may not
be compatible. Make sure that the Switch is compatible with the
terminals.
Comparison of the D4DH and Substitute Products
