Note: 1. The above values are initial values.
2. 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.
*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 D4NS in places where foreign
material may enter through the key hole on the head, otherwise
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. These figures are minimum requirements for safe operation.
*5. This value will vary with the switching frequency, environment,
and reliability level. Confirm that correct operation is possible with
the actual load beforehand.

Safety Precautions
Be sure to read the precautions for All Safety Door Switches in the website at:http://www.ia.omron.com/.
Indication and Meaning for Safe Use
CAUTION
Precautions
for Safe Use
Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or in property damage.
Supplementary comments on what to do
or avoid doing, to use the product safely.
Supplementary comments on what to do
or avoid doing, to prevent failure to
operate, or undesirable effect on product
performance.
Precautions
for Correct
Use
<Safety-door Switch D4NS>
!CAUTION
Electric shock may occasionally occur.
Do not use metal connectors or metal conduits.
Precautions for Safe Use
• Do not use the Switch submersed 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. (The IP67 degree of
protection of the Switch specifies the amount of water penetration
after the Switch is submerged in water for a certain 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.
Mounting Method
Appropriate Tightening Torque
• Loose screws may result in malfunction. Tighten the screws to the
specified torques.
Terminal screw
0.6 to 0.8 N·m
Cover mounting screw
0.5 to 0.7 N·m
Head mounting screw

Body mounting screw
0.5 to 0.7 N·m
Connector
1.8 to 2.2 N·m
Cap screw
1.3 to 1.7 N·m
• When loosening a screw with an electrical screwdriver or similar
tool while pressing down on the screw head, do not continue
turning the screw past the point where the threads disengage.
Doing so may strip the end of the threads.
Mounting Holes
• Use M4 screws and spring washers to mount the Switch and
Operation Key, and tighten the screws to a suitable torque. To
ensure safety, use screws that cannot be easily removed or
another means to prevent the Switch and Operation Key from
easily being removed.
• As shown below, two studs with a maximum height of 4.8 mm and
a diameter of 4 −0.05
−0.15 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.

Stopper Installation
Do not use a Switch as a stopper. Be sure to install a stopper as
shown in the following illustration to ensure that the base of the
Operation Key does not strike the Head, and adjust the stopper to be
within the setting zone (0.5 to 3 mm) of the base of the Operation Key.
Do not subject the Switch to a shock that exceeds the Switch's shock
resistance of 1,000 m/s2.

Precautions for Correct Use
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.
4-0.15 dia.
Height: 4.8 max.
• Set the Operation Key so that it is within 1 mm of the center of the
key hole. If the Operation Key is offset or at an angle, accelerated
wear or breaking may result.
• Observe the specified insertion radius for the Operation Key and
insert it in a direction perpendicular to the key hole.

D4NS/D4NS-SK
Head Direction
• The rotation of the Switch head may be adjusted to any of the four
directions by loosening the head mounting screws at the four
corners of the head. Make sure that no foreign materials enter
through the head.
• Do not insert or remove the Operation Key with the Switch head
removed. Doing so may make it impossible to insert the Operation
Key.

The crimp terminals listed below have a thickness of 0.5 mm or less.

Wiring
• When connecting with insulation tubes and M3.5 crimp terminals,
connect the terminals as shown in the following figure and wire
without overriding to the case and the cover. Adequate conductor
size is AWG 20 to AWG18 (0.5 to 0.75 mm2).
Prepare lead wires using the lengths given in the following
diagrams. If lead wires are too long, they will press against the
cover causing the cover to not close properly.

• Turn the tightening screws on the Socket by hand and tighten them
until the gap between the Socket and Plug essentially disappears.
• Make sure that the Socket’s connector is tightened securely,
otherwise the rated degree of protection (IP67) of the D4NS may
not be maintained, or the Socket connector may be loosened by
vibration.

• Do not push the crimp terminal and the likes into the opening
between the parts to prevent the case from being broken and
deformed.
• Use terminals having the thickness of 0.5 mm or less to avoid the
contact between the terminal and the Switch case inside.
• Use cables with suitable diameters for the connector being used.
• When wiring, place the enclosed cap screw on unused conduit
openings (for 2-Conduit Switches) and tighten them to the suitable
tightening torque.
Recommended Connectors
Use the connector with thread section of 9 mm long or less. If a
connector with a longer thread section is used, the protruding part
may interfere with the other parts inside the body. Use the connectors
listed below to ensure IP67 degree of protection.

Technical Specifications
!CAUTION
D4NS-SK30
Incorrect operation may cause injury. Also, the product is
designed to be mounted so that it slides horizontally.
Do not mount the product in a vertically sliding
configuration.
(excluding the D4NS-SK01)
Precautions for Safe Use
• Do not drop the Switch. Doing so may prevent the Switch from
functioning to full capacity.
• Mount the Switch securely to prevent it from falling. Otherwise,
injuries may occur.
• Do not attempt to disassemble or modify the Switch. Doing so may
cause the Switch to malfunction.
• Make sure that the gap between the short bolt and guide is (±3
mm. Otherwise, excessive wear or damage may cause
malfunction.
• To ensure safety, do not operate the Switch with anything other
than a Slide Key.
• Be careful to avoid pinching your hand when operating the Switch.
• Be sure to mount the Switch protective cover. Otherwise, your
hand may be injured by being pinched between the shot bolt and
Switch when closing the door with your hand on the Switch.
• When opening the door, be sure to lower the disable-prevention
cover into position, attach a padlock, or take other steps to prevent
other people from operating the Switch.
• The durability of the Switch is greatly influenced by the switching
conditions. Always test the Switch under actual working conditions
before application and use it in a switching circuit for which there
are no problems with performance.
• The user must not maintain or repair equipment incorporating the
Switch. Contact the manufacturer of the equipment for any
maintenance or repairs required.
• Do not shut the door while the shot bolt is extended. The Switch
may be damaged, preventing proper operation.
• Do not apply excessive force in the direction of the slide. This may
damage the product and cause it to malfunction.
