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 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.

Circuit Connection Example
• Direct opening contacts used as safety-circuit input are indicated
with the
mark.
• Do not switch circuits for three or more standard loads at the same
time.
Doing so may adversely affect insulation performance.
• DC solenoids have polarity. (E1: Positive, E2: Negative)
Confirm terminal polarity before wiring.

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. If a current is detected in the solenoid lock model (built-in switches; N,P,Q,R), before the door is closed, the door will remain unlocked.
Be sure to supply power to the solenoid after the door is closed.

Safety Precautions
Refer to the “Precautions for All Switches” and
“Precautions for All Safety Door Switches”.
Precautions for Correct Use
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.
CAUTION
Injury may occasionally occur. When the Switch
function is damaged, some machines may continue
operating in situations where they should be stopped.
Do not impose a force exceeding the key holding
force. Always provide a lock separate from the Switch, attach a
warning seal to avoid excessive force applied to the Switch, or
provide an indicator lamp to show the locked/unlocked status of
the door.
Solenoid Lock Models
• If a current is detected in the solenoid lock model (built-in switches;
N,P,Q,R), before the door is closed, the door will remain unlocked.
Be sure to supply power to the solenoid after the door is closed
(after the Operation Key is inserted).
• 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).

Precautions for Safe Use
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, 1
A). Doing so may adversely affect insulation performance.
• Do not allow the load current to exceed the rated value.
• For metal connector, use a connector with the screw length of 9
mm or less. Otherwise it may result in electric shock.
• Do not use metallic conduits. In the event of damage to the conduit
opening, this may cause seal failure and may result in electric
shock.
• Do not use a metal connector for a 1/2-14NPT connector. 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.
Installation
• Make sure the Switch is mounted securely to prevent it from falling
off. Otherwise injury may result.
• Do not use a Switch as a stopper.
Head
Stopper
Be sure to install a stopper as shown in the
following illustration so that the Operation
Key does not touch the head.
Do not subject the Switch to a shock that
exceeds the Switch's shock resistance of
Operation Key
1,000 m/s2.

LOCK
LOCK
• 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-@@@A and to the lock position for the D4SL-@@@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.
D4SL
Mounting
Spacer
Appropriate Tightening Torque
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.
Loose screws may result in malfunction. Tighten the screws to the
specified torques.

• Direct opening contacts used as safety-circuit inputs are indicated
with the
mark. Terminals 11-42, and terminals 21-52 have
direct opening contacts.
• 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.

• Ensure that the alignment offset between the Operation Key and
the key hole does not exceed ±0.8 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.
• Mount a provided cap head to an unused Operation Key hole.
• Perform 3-point mounting including the head for side mounting.
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.
