Operating Cycle Examples for Standard Models
D4SL-N@@@A-@ (Mechanical Lock Models)
D4SL-N@@@G-@ (Solenoid Lock Models)
Door open/closed detection and lock monitor contacts: Can be used in safety circuits because of the direct opening mechanisms.
Door open/closed detection contact: Can be used to confirm whether the key is inserted and to monitor the open/closed status of a door.
Lock monitor contact: Can be used to confirm whether power is supplied to the solenoid and to monitor whether or not a door can be opened or closed.
Note: 1. The door open/closed detection and lock monitor contact configuration depends on the model.
2. For solenoid lock models, be sure to supply power to the solenoid after the door is closed (after the operation key is inserted).
If the door is closed after power is supplied to the solenoid, locking the operation key may not be possible.
For details, refer to “Solenoid Lock Models” on page 23.

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, oil or water penetration, do not use the D4SL in places where cutting chips, oil, water or
chemicals 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 1 A, 125 VAC load through more than 3 circuits.
*4. These figures are minimum requirements for safe operation.
*5. This figure is based on the ISO 14119 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.

D4SL-N
Operating 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 three or more standard loads (125 VAC,
1A). Doing so may adversely affect insulation performance.
•Do not allow the load current to exceed the rated value.
•For metal cable glands, use a cable gland with the screw length of
9 mm or less. Otherwise it may result in electric shock.
•Do not use metal conduits. Damage to the conduit outlet may result
in an improper seal or electric shock.
•Do not a use metal cable gland for the conduit outlet of 1/2-14NPT.
In the event of damage to the conversion adapter, this may cause
seal failure and may result in electric shock.
•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.
•When using the terminal block type, make sure that foreign
material does not adhere to the terminal block board. Otherwise a
short circuit may occur between terminals and safety functions
may fail to work properly.

damage the product. The cable should be fixed at
a point separate from the switch.
D4SL-N
Solenoid Lock Models
•For solenoid lock models, be sure to supply power to the solenoid
after the door is closed (after the operation key is inserted). If the
door is closed after power is supplied to the solenoid, locking the
operation key may not be possible. (The solenoid carry current is
applied for Approx. 10 seconds, after which the internal circuit
switches to a constant current. The lock may not operate properly
while the constant current is applied.)
•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.
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).
Å@
•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.
•After setting the release key to UNLOCK to, for example, perform
maintenance, be sure to return it to LOCK setting before resuming
operation.
•The release key is set in the unlock position at the factory for the
D4SL-N@@@A and to the lock position for the D4SL-N@@@G.
•In the unlock position, even when the door of large machines or
stamping machines is closed during preliminary adjustment, the
door will remain unlocked and the machines will not be activated.
•Do not use the release key to start or stop machines.
•The auxiliary lock must be released only by authorized personnel.
•Do not impose a force exceeding 0.2 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.

Mounting Covers
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.
Hinged Door
•If the Switch is mounted too close to the hinge, the force imposed
on the lock will be much larger than for locations far from the hinge
and the lock may be damaged. Mount the Switch close to the
handle.
Mounting
Appropriate Tightening Torque
Loose screws may result in malfunction. Be sure to tighten each
screw of the Switch properly.
Switch and Operation Key Mounting
•Mount the Switch and Operation Key securely to the applicable
tightening torque with M4 screws. Always use washers.
•The switch can be fastened more firmly by a stud (4 mm dia., 1.5
mm max height) inserted from back side at the hole of the switch.
•Do not impose excessive force on the key top while the operation
key is inserted into the switch body or drop the switch with the
operation key inserted to avoid the deformation of the key or the
breakage of the switch body.
•Do not use the operation key other than dedicated OMRON's
(D4SL-NK@). Otherwise switch may be damaged.
•Do not use the operation key D4SL-K@. A lock will not be closed
and a machine will not be activated.
•Be sure that the operation key can be inserted properly to key hole
with a tolerance of ±0.8 mm.
•Insert the operation key into the key hole according to the specified
“operation key insertion radius in horizontal direction”.
•When mounting at the side of switch body, mount the switch with 3
points including the head.
•Attach cap heads to any operation key holes that are not being
used.
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 (hook)
so that the Operation Key remains
within the set zone.
Spacer
Do not remove a spacer. Rotate the spacer in accordance with the
Switch mounting direction. Use of the Switch without spacer will
reduce the lock strength.
Wiring
•DC solenoids have polarity. (E1: +, E2: −) Confirm terminal polarity
before wiring.
•The current of the 24 VDC solenoid is different from when it is first
turned ON as to when it is in operation. To take into account
possible voltage drops, it is important to apply a rated operation
voltage.
•To enable the 24 VDC solenoid, it is necessary to select the
appropriate power supply capacity.
•The ON and OFF contact operation will not engage
simultaneously.
Be sure to confirm operation under actual operating conditions.
•If a lock is required for safety, design the system so that the closing
of the NC contacts on both the door open/closed detection switch
and the lock monitor switch is detected.
