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
D4NL 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 figure is based on the GS-ET-19 evaluation method.
*6. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual
load beforehand.

• Terminals 12 and 41 are connected internally. When connecting
inputs to safety circuits, use terminals 11 and 42. (GS-ET-19).
• Connect terminals 21 and 22 and terminals 51 and 52 in series
when using as safety-circuit inputs (redundancy circuit for
terminals 11 and 12 and terminals 41 and 42 below). Connect the
terminals individually when using as auxiliary-circuit inputs (e.g.,
terminals 21 and 22 for safety-door open/closed monitoring and
terminals 51 and 52 for monitoring the lock status).
• In the following connection example, terminals 21 and 22 and
terminals 51 and 52 are used as auxiliary-circuit inputs.
• Direct opening contacts used as safety-circuit inputs are indicated
with the
mark. Terminals 11 and 42, and terminals 21 and 22
have direct opening contacts.
• Connect the indicators in parallel to the auxiliary circuits or
terminals E1 and E2 (D4NL-@@@A-B, -@@@G-B, -@@@B-B, and
-@@@H-B only).
Connecting to contacts with direct opening mechanisms may result
in short-circuit current flowing if the indicator is destroyed, possibly
resulting in incorrect equipment operation.
• Do not switch circuits for two or more standard loads at the same
time. Doing so may adversely affect insulation performance.
• DC solenoids have polarity. Confirm terminal polarity before wiring.

models
If the solenoid is OFF, the door will not be
locked when the Operation Key is
inserted. This means that the door can be
opened and closed easily when replacing
workpieces or parts.
Spring
Lock plate
The door is locked only when the solenoid
is turned ON. This means that the door will
be unlocked if there is a power interruption
and so this model cannot be used in
systems that would maintain a hazardous
state (e.g., systems requiring toxic gases,
high temperatures, or gears that would
continue to turn due to inertia).

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
DANGER
CAUTION
Indicates an imminently hazardous
situation which, if not avoided, is likely to
result in serious injury or may result in
death. Additionally there may be severe
property damage.
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.
• Always attach the cover after completing wiring and before using
the Switch. Do not supply power when the cover is not attached.
Electric shock may occur if the Switch is used without the cover
attached.
Installation
• Make sure the Switch is mounted securely to prevent it from falling
off. Otherwise injury may result.
• Do not use the 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.
Operation Key
Stopper
Set zone
(0.5 to 3 mm)
DANGER
Injury may occasionally occur. Always check to make
sure that the safety functions operate correctly before
using the machine. The safety functions may not operate
correctly because of wiring mistakes, setting mistakes,
or Switch malfunction, causing some machines to
continue operating in situations where they should be
stopped.
Injury may occasionally occur. If the machine is used
with the release key in the UNLOCK position, the
electromagnetic lock may not operate, causing some
machines to continue operating in situations where they
should be stopped. Be sure to put the release key in the
LOCK position before using the machine. Also, check
the condition of the lock and safety circuits.
Injury may occasionally occur. Always ensure that the
release key is set to "UNLOCK" or that the Operation
Key is inserted before changing the direction of the head.
Not doing so may damage the Switch, causing some
machines to continue operating in situations where they
should be stopped. Refer to “Release Key” on page 16.
Injury may occasionally occur. When the
electromagnetic lock function or Switch function is
damaged, some machines may continue operating in
situations where they should be stopped. Do not use the
electromagnetic lock function of the Switch in place of a
door lock. Always provide a lock separate from the
Switch, attach a warning seal to prevent people from
using excessive force to open the door when it is locked,
or provide an indicator lamp to show the locked/unlocked
status of the door.
UNLOCK
LOCK
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.
Release Key
• The release key is used to unlock the Switch in case of emergency
or if the power supply to the Switch stops.
• If the release key setting is changed from LOCK to UNLOCK, the
lock will be released and the safety door can be opened
(mechanical lock models only).
• When a Switch with a solenoid lock is in a locked state (i.e., when
the solenoid is ON), do not change the release key from the LOCK
to the UNLOCK position. Internal parts may be damaged.
• The release key is set in the unlock position at the factory for the
D4NL-@@@A/B/C and to the lock position for the D4NL-@@@G/H/J.
• Do not use the release key to start or stop machines.
• The auxiliary lock must only be released by authorized personnel.
• Do not impose a force exceeding 1 N·m on the release key screws.
The release key may be damaged and may not operate properly.
• To prevent the release key from being used by unauthorized
personnel, set it to LOCK and seal it with sealing wax.

Precautions for Safe Use
Installation Environment
• 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.)
Wiring
• Do not switch circuits for two or more standard loads (250 VAC,
3 A). Doing so may adversely affect insulation performance.

LOCK
Hinged Door
If an attempt is made to open the door beyond the lock position when the
Switch is used for a hinged door at 3a location near to the hinged side,
where the Operation Key’s insertion radius is comparatively small, the
force imposed will be much larger than for locations far from the hinged
side, and the lock may be damaged. Mount the Switch close to the handle.

Solenoid Lock Models
Attaching a Cover
The solenoid lock locks the door only when power is supplied to the
solenoid. Therefore, the door will be unlocked if the power supply to
the solenoid stops. Therefore, do not use solenoid lock models for
machines that may be operating and dangerous even after the
machine stops operating.
Mounting
Securing the Door
Appropriate Tightening Torque
• Be sure to tighten each screw of the Switch properly. Loose screws
may result in malfunction.
Type
Appropriate tightening torque
Terminal screw
0.59 to 0.78 N·m
Cover mounting screw
0.49 to 0.69 N·m
Head mounting screw

• 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.
Switch and Operation Key Mounting
• 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.

• 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.

• If the Switch is back-mounted, the release key can be operated
only from the bottom and the indicator cannot be used.
• Ensure that the alignment offset between the Operation Key and
the key hole does not exceed ±1 mm. If the Operation Key is offset
or at an angle, accelerated wear or damage to the Switch may
result.
• Observe the specified insertion radius for the Operation Key and
insert it in a direction perpendicular to the key hole.
• 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.
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.
Then, when an attempt is made to open the door, it may result in
damage or malfunction. Also, it may not be possible to unlock the
Switch if there is weight placed on the Operation Key. Do not rely on
the Switch to substitute for a door locking device. Secure the door with
a stopper so that the Operation Key remains within the set zone.

terminals 11 and 12 and terminals 41 and 42 below). Connect the
terminals individually when using as auxiliary-circuit inputs (e.g.,
terminals 21 and 22 for safety-door open/closed monitoring and
terminals 51 and 52 for monitoring the lock status).
• In the following connection example, terminals 21 and 22 and
terminals 51 and 52 are used as auxiliary-circuit inputs.
• Connect the indicators in parallel to the auxiliary circuits or
terminals E1 and E2 (D4NL-@@@A-B, -@@@G-B, -@@@B-B, and
-@@@H-B only).
Connecting to contacts with direct opening mechanisms may result
in short-circuit current flowing if the indicator is destroyed, possibly
resulting in incorrect equipment operation.

Wiring Precautions
• Do not wire the Switch while power is being
supplied. Doing so may result in electric shock.
• Do not let particles, such as small pieces of lead
wire, enter the switch body when wiring.
• When connecting to the terminals via insulating
tube and M3.5 crimp terminals, cross the crimp
terminals as shown above 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. Not doing so may result in
excess length causing the cover to rise and not fit properly.
• Do not push crimp terminals into gaps in the case interior. Doing so
may cause damage or deformation of the case.
• Use terminals having the thickness of 0.5 mm or less to avoid the
contact between the terminal and the interior of the Switch case.
[Reference] The terminals listed below have thickness of 0.5 mm or
less.
