Note: Contact your sales representative for details
on models with safety standard certification.
• A mechanical lock is applied automatically when the Operation
Key is inserted. A high level of safety is achieved using a
mechanism where the lock is only released when voltage is
applied to the solenoid.
• Conforms to EN (TÜV) standards corresponding to the CE
marking.
• Certified by UL, CSA and CCC standards.
• The Switch contact is opened by a direct opening mechanism
(NC contacts only) when the protective cover is opened.
Direct opening mechanism that is EN-certified is indicated by
on the Switch.
• Auxiliary release key ensures easy maintenance and unlocks the
door in the case of a power failure.
• Tough aluminum die-cast body incorporating a switch box with
degree of protection satisfying IP67, UL, and CSA TYPE6P, 13.
• Equipped with a horizontal and vertical conduit opening.
• Models incorporating easy-to-see indicators for monitoring and
those using an adjustable Operation Key for a swinging door are
available.
• The mounting direction of the head can be changed
to allow the Operation Key to be inserted from four
directions.
Be sure to read the “Safety Precautions” on page 13.

the operating conditions and environment beforehand. Although the switch box is protected from dust, oil or water penetration, do not use the
D4BL in places where dust, 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%.

Circuit Connection Example
• Terminals 11 and 32 are connected internally and so connect terminals 12 and 31 for safety-circuit input. (GS-ET-19).
• When using indicators, connect them to the auxiliary circuit side (monitor circuit) or in parallel between E1 and E2 as shown below.
• Do not connect the indicators in parallel with the direct opening contact. If the indicators are broken, a short-circuit current may flow, causing
equipment to malfunction.
• The 24 VDC solenoid terminals have polarity. Confirm the polarity before wiring.

Safety Precautions
● Be sure to read the precautions for all D4BL models in the website at: http://www.ia.omron.com/.
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.
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. 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.
Appropriate Tightening Torque
Loose screws may result in malfunction. Tighten the screws to the
specified torques.

Precautions for Safe Use
• 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.
• Make sure the Switch is mounted securely to prevent it from falling
off. Otherwise injury may result.

Auxiliary Release Key
Do not use a Switch as a stopper. Be sure to install a stopper as
shown in the following illustration when mounting the Switch so that
the Operation Key is within 0.5 to 5 mm of the set zone.
Do not subject the Switch to a shock that exceeds the Switch's shock
resistance of 1,000 m/s2.
• The auxiliary release key is used to unlock the D4BL in case of
emergency or in case the power supply to the D4BL fails.
• Use the enclosed Release Key to change the lock from LOCK to
UNLOCK so that the lock will be released and the door can be
opened. (Applies only to mechanical locks. Release key is not
provided with D4BL-2GRD-AT.)

• 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.
• Whenever the lock has been changed to UNLOCK, always return
it to LOCK before using the Switch.
• Do not use the auxiliary release key to start or stop machines.
• Make sure that the auxiliary release key is kept with the person in
charge.
• To prevent the auxiliary release key from being handled carelessly
by unauthorized people, seal the auxiliary release key with sealing
wax and the provided seal cap to ensure IP67.
• Before attaching the cover to the D4BL, make sure that the
auxiliary release key position is set to LOCK.

D4BL
Solenoid Lock Models
Head Direction
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.
Switch and Operation Key Mounting
Use four M5 screws and spring 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.
• The head can be mounted in four directions by loosening the four
screws holding the head. To remove the head, turn the head at the
surface mating with the Switch body by 45° as shown in figures (A)
and (B) below.
To change the direction of the head, make sure that the protruding
part of the rotating lever engages with the groove of the plunger.
Then turn the head clockwise or counterclockwise to the desired
direction. At that time, make sure that the groove of the plunger is
located under the rotating lever. If the direction of the head is not
set when the plunger is rotated by 45°, the groove of the plunger
presses the rotating lever. The head, plunger, or the built-in switch
may be damaged as a result.

• The D4BL is provided with a shock-absorbing damper to protect
the D4BL from damage that may result from dropping the D4BL
during transportation. Be sure to remove the damper after
mounting the D4BL.
• The mounting tolerance of the Operation Key is ±0.3 mm vertically
or horizontally. Be sure to mount the D4BL correctly without
misalignment, otherwise the D4BL may soon break or wear out.
• Observe the specified insertion radius for the Operation Key and
insert it in a direction perpendicular to the key hole.

• Be sure to check the mechanical lock and solenoid release
functions when mounting the D4BL.
• If the head direction is changed, recheck the tightening torque of
each of screw. Make sure that no foreign materials will enter
through the key hole on the head.

Cable Connection Example
1. Connect the wires to the terminals in the order shown below for
wiring efficiency.
• The following procedures are recommended for mounting and
wiring the indicator unit securely.
• To ensure IP67, use OMRON’s SC-@M and Nippon Flex’s
ABS-08Pg13.5 and ABS-12 Pg13.5 Connectors.
• Recommended cable: UL2464-type cable that is AWG20 to
AWG18 (0.5 to 1.0 mm2) in size and has seven conductors
• Connect the indicator unit after connecting the seven-conductor
cable.
Tighten each wired terminal clockwise to a torque of 0.59 to
0.78 N·m.

Twist the wire two or three times and make sure that no bare wire
exists outside the terminal when tightening the terminal.
2. The insulation sheath of the seven-conductor cable must come into
contact with the wall of the conduit mouth, side A or side B.

• Properly attach and securely tighten the provided conduit cap to
the unused conduit opening to the suitable tightening torque when
wiring the D4BL.
