Solenoid Lock Models
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
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
0.49 to 0.59 N·m
Operation Key mounting screw
2.35 to 2.75 N·m
Switch mounting screw
0.49 to 0.69 N·m
Connector
1.77 to 2.16 N·m
Cap screw
1.27 to 1.67 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.
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.

• 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.
Head Direction
• Remove the four screws of the head to enable changing the
mounting direction of the head. The head can be mounted in four
directions. Ensure that no foreign material enters the interior of the
Switch.
• Do not change the head direction with the cover removed.
• Do not insert or remove the Operation Key with the Switch head
removed. Doing so may make it impossible to insert the Operation
Key.
Attaching a Cover
• 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.
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.
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.

Solenoid
• The solenoid will heat when it carries current. Do not touch it.
• A DC solenoid has polarity. Confirm terminal polarity before wiring
it.
Wiring
Circuit Connection Example for the D4NL-@F@@-B
• 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 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.
• 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.
