Low Voltage Directive
EN50047
EN60947-5-1
EN ISO 14119
GS-ET-15
Certified Standards
*1. Certification for CSA C22.2 No. 14 is authorized by the UL mark.
*2. Only certain models have been certified.
Certified Standard Ratings
TÜV (EN60947-5-1), CCC (GB/T 14048.5)
Note: Use a 10 A fuse type gI or gG that conforms to IEC60269 as a
short-circuit protection device. This fuse is not built into the
Switch.
UL/CSA (UL508, CSA C22.2 No. 14)

Q300
Characteristics
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
<Safety-door Switch D4NS>
!CAUTION
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.
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.
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
Loose screws may result in malfunction.
Be sure to tighten each screw of the Switch properly.
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 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 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.
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.
Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or in property damage.

Operation Key
Use only the designated Operation Key. The Head has been
designed so that operation is not possible with a screwdriver or
other tools. Using anything other than the designated Operation
Key may damage the Switch or affect machine safety.
Do not operate the Switch with anything other than the special
OMRON Operation Key, otherwise the Switch may break or the
safety of the system may not be maintained.
Do not impose excessive force on the Operation Key while the Key
is inserted into the Switch or drop the Switch with the Operation
Key inserted. Doing either of these may deform the Key or break
the Switch.
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.
Securing the Door
When the door is closed (with the Operation Key inserted), the
Operation Key may exceed the set zone because of, for example, the
door's own weight, machine vibration, or the door cushion rubber.
Secure the door with a stopper so that the Operation Key remains
within the set zone.
Wiring
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.
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.
<Reference>
The crimp terminals listed below have a thickness of 0.5 mm or less.
J.S.T is a Japanese manufacturer.
Pin arrangement of connector type
Suitable socket is XS2F-D421 series (OMRON).
Refer to the Connector Catalog for corresponding Socket pin
numbers and lead wire colors.
Socket Tightening (Models with Connectors)
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.
Conduit Outlet
Use a cable conforming to the diameter of the cable gland to be
used.
When wiring, place the enclosed cap screw on unused conduit
outlets (for 2-Conduit Types) and tighten them to the suitable
tightening torque.
Cable Gland
Use a commercially available cable gland.
Use the cable gland with thread section of 9 mm long or less.
