G-174 Safety Sensors / Components
Characteristics
Note: 1. The above values are initial values.
2. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are suffi-
cient for the operating conditions and environment beforehand. Although the switch box is protected from dust or water penetration, do
not use the D4GL in places where foreign material may penetrate through the key hole on the head, otherwise Switch damage or mal-
functioning may occur.
3. The durability is for an ambient temperature of 5°C to 35°C and an ambient humidity of 40% to 70%. For more details, consult your OM-
RON representative.
4. If the ambient temperature is greater than 35°C, do not pass the 1-A, 125-VAC load through more than 2 circuits.
5. These figures are minimum requirements for safe operation.
6. This figure is based on the GS-ET-19 evaluation method.
7. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual
load beforehand.
Degree of protection (See note 2.) IP67 (EN60947-5-1)
(This applies for the Switch only. The degree of protection for the key hole is IP00.)

Connections

Internal Circuit Diagram
Circuit Connection Example
•Terminals 12 and 41 are connected internally and so connect ter-
minals 11 and 42 for safety-circuit input. (BIA GS-ET-19)
•Connect terminals 21 and 22 and terminals 51 and 52 in series
when using as safety-circuit input (redundancy circuit for terminals
11 and 12 and terminals 41 and 42 above). Connect the terminals
individually when using as auxiliary-circuit input (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 ter-
minals 51 and 52 are used as auxiliary-circuit input.
Connection Example for D4GL-1HFA-A
•Direct opening contacts used as safety-circuit input are indicated
with the mark. Terminals 11 and 12 and terminals 21 and 22
are direct opening contacts.
•Connect the indicators in parallel to the auxiliary circuits or termi-
nals E1 and E2.
•Although the 3 lines are connected at the time of delivery, rewire
them as necessary for the application.
•The following table shows the connection configuration required to
make the green indicator light when the door is closed and the
orange indicator light when the solenoid turns ON.
•If an indicator is connected in parallel to a direct opening contact,
when the indicator breaks, a short-circuit current will be generated,
possibly resulting in an installation malfunction.
•Do not switch standard loads for more than 2 circuits at the same
time. Otherwise, the level of insulation may decrease.
•The solenoid has polarity. Be sure to connect terminals with the
correct polarity.

Structure
Note: Terminal numbers vary with the model. Confirm terminal numbers by referring to the cover on the back of the Switch.
Mechanical
lock models
When the door is closed, it is locked by the
lock spring. The door will stay locked even
if there is a power interruption.
The solenoid is released only when the
lock is turned ON.
Solenoid
lock models
If the solenoid is OFF, the door will not be
locked when it is closed. This means that
the door can be opened and closed easily
when replacing workpieces or parts.
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 sys-
tems that would maintain a hazardous
state (e.g., systems requiring toxic gases,
high temperatures, or gears that would
continue to turn due to inertia).

G-182 Safety Sensors / Components
Precautions
!Caution
Do not insert the Operation Key with the door open. The
machine may operate and damage may result.
!Caution
Do not use metal connectors or conduits with this switch.
Damage to the broken conduit hole may cause electric shock.
!Caution
Change the head direction after inserting the Operation Key or
changing the release key to the UNLOCK position. Otherwise,
the switch may malfunction and damage may result.
Holding Force
•Do not apply a force exceeding the specified holding force. Doing
so may break the Switch and the machine may continue to operate.
•Either install another locking component (e.g., a stop) in addition to
the Switch, or use a warning sticker or an indicator showing the
lock status so that a force exceeding the specified holding force is
not applied.
Safety Precautions
•Turn OFF the power before disassembling the Switch or touching
any internal parts. Not doing so may result in electric shock.
•Mount the Operation Key in a location where it will not come in con-
tact with users when the door is opened or closed. Otherwise,
injury may result.
•Do not impose excessive force on the Operation Key when it is
inserted into the Switch or drop the Switch with the Operation Key
inserted. Otherwise, the Operation Key may be deformed or the
Switch may be broken.
•Observe the specified insertion radius for the Operation Key and
insert it in a direction perpendicular to the key hole.
•Do not use the Switch in starting circuits. (Use for safety confirma-
tion signals.)
•When using the Switch in emergency-stop circuits or other safety
circuits that have a direct impact on human lives, operate the NC
contacts that have a direct opening mechanism in direct opening
mode. For safety purposes, prevent easy removal by, for example,
mounting the Switch and Operation Key with one-way screws or
attaching a protective cover and warning label.
•In order to prevent short-circuit damage to the Switch, connect a
fuse to the Switch in series. Use a fuse with a breaking current of
1.5 to 2 times the rated current. To conform to EN ratings, use a
IEC269-compliant 10-A fuse type gI or gG.
•Turn the power OFF when wiring. After wiring is completed, be sure
to mount the cover before use.
•In order to prevent burning due to overvoltage, insert a protective
fuse in the solenoid circuits.
•Do not use the Switch where explosive gas, flammable gas, or any
other dangerous gas may be present.
•Ensure that the load current does not exceed the rated current.
•Be sure to wire the terminals correctly.
•Be sure to evaluate the Switch under actual operating conditions
after installation.
•Do not drop the package or the product. Do not disassemble inter-
nal parts.
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 using
an appropriate tool, the lock will be released and the safety door
can be opened (mechanical lock models only).
•After setting the release key to UNLOCK in order to, for example,
change the head direction or perform maintenance, be sure to
return it to LOCK setting before resuming operation.
•When the Switch is used for the door of a machine room to ensure
the safety of people performing adjustment work inside, if the
release key is set to UNLOCK, the door will not be locked when the
door is closed and no power will be supplied to the equipment.
•Do not use the release key to start or stop machines.
•The auxiliary lock must only be released by authorized personnel.
•Do not impose excessive force on the release key screws. The
release key may be damaged and may not operated properly.
•To prevent easy release of the auxiliary lock by unauthorized per-
sonnel, set it to LOCK and seal it with seal wax.
Mounting
•Do not use the Switch as a stopper. To prevent the door from com-
ing into contact with the flange of the Operation Key, be sure to
mount the Switch with a stopper as shown above.
•When the Switch is used for a hinged door at a location near to the
hinged side, where the Operation Key’s insertion radius is compar-
atively small, if an attempt is made to open the door beyond the
lock position, the force imposed will be much larger than for loca-
tions far from the hinged side, and the lock may be damaged.
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.

Correct Use
Operating Environment
•This Switch is for indoor use only. Do not use it outdoors. Other-
wise, it may malfunction.
•Do not use the Switch in the following locations:
•Locations subject to severe temperature changes
•Locations subject to high humidity levels or condensation
•Locations subject to severe vibration
•Locations where the Switch may come in contact with metal dust,
oil, or chemicals
•Locations subject to thinner, detergent, or other solvents
•Although the switch itself is protected from dust or water penetra-
tion, ensure that foreign material does not penetrate through the
key hole on the head, otherwise Switch damage or malfunctioning
may occur.
•Do not use the Switch submerged 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 interior. (The IP67 degree of pro-
tection specification for the Switch pertains to the amount of water
penetration after the Switch is submerged in water for a certain
period of time.)
Life Expectancy
The life expectancy of the Switch will vary with the switching condi-
tions. Before applying the Switch, test it under actual operating con-
ditions and be sure to use it at a switching frequency that will not
lower its performance.
Mounting
Tightening Torque
Be sure to tighten each screw of the Switch properly. Loose screws
may result in malfunction.
Switch and Operation Key Mounting
•Mount the Switch and Operation Key securely to the applicable
tightening torque with M5 screws.
]
•Use the designated OMRON Operation Key with the Switch. Using
another Operation Key may result in Switch damage.
•Ensure that the alignment offset between the Operation Key and
the key hole does not exceed ±1 mm.
Head Direction
By removing the four screws of the head, the mounting direction of
the head can be changed. The head can be mounted in four direc-
tions.
Ensure that no foreign matter penetrates the interior of the Switch.
Also, insert the head until the insertion line engraved on the head is
hidden by the reference line on the Switch, as shown in the following
diagram.
Securing the Door
When the door is closed (with the Operation Key inserted), it may be
pulled beyond the set zone because of, for example, the door’s
weight, or the door cushion rubber. Also, if a load is applied to the
Operation Key, the door may fail to unlock properly. Use hooks to
ensure that the door stays within the set zone.
Wiring
Wiring Precautions
•Applicable lead wire size: AWG22 to AWG24.
•When connecting lead wires directly to terminals, perform wiring
securely so that there are no loose wire strands.
•Do not push crimp terminals into gaps in the case interior. Doing so
may cause damage or deformation of the case.
•Use lead wires of an appropriate length. Not doing so may cause
the cover to rise.
•Use crimp terminals not more than 0.5 mm in thickness. Otherwise,
they will interfere with other components inside the case.

G-184 Safety Sensors / Components
Circuit Connection Example
•Terminals 12 and 41 are connected internally and so connect termi-
nals 11 and 42 for safety-circuit input. (BIA GS-ET-19)
•Connect terminals 21 and 22 and terminals 51 and 52 in series
when using as safety-circuit input (redundancy circuit for terminals
11 and 12 and terminals 41 and 42 above). Connect the terminals
individually when using as auxiliary-circuit input (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 ter-
minals 51 and 52 are used as auxiliary-circuit input.
Connection Example for D4GL-1HFA-A
•Direct opening contacts used as safety-circuit input are indicated
with the mark. Terminals 11 and 12, terminals 21 and 22, and
terminals 31 and 32 are direct opening contacts.
•Connect the indicators in parallel to the auxiliary circuits or termi-
nals E1 and E2.
•Although the 3 lines are connected at the time of delivery, rewire
them as necessary for the application.
•The following table shows the connection configuration required to
make the green indicator light when the door is closed and the
orange indicator light when the solenoid turns ON.
•If an indicator is connected in parallel to a direct opening contact,
when the indicator breaks, a short-circuit current will be generated,
possibly resulting in an installation malfunction.
•Do not switch standard loads for more than 2 circuits at the same
time. Otherwise, the level of insulation may decrease.
•The solenoid has polarity. Be sure to connect terminals with the
correct polarity.
Conduit Opening
•Connect a recommended connector to the opening of the conduit
and tighten the connector to the proper torque. The case may be
damaged if an excessive tightening torque is applied.
•In order to ensure IP67 degree of protection, wrap sealing tape
around the conduit end of the connector.
•Be sure that the outer diameter of the cable connected to the con-
nector is correct.
•Attach and tighten a conduit cap to the unused conduit opening
when wiring. The conduit cap is provided with the Switch.
Recommended Connectors
Use a connector with a screw section not exceeding 10 mm, other-
wise the screws will protrude into the case interior. The connectors
given in the following table have connectors with screw sections not
exceeding 10 mm.
Use LAPP connectors together with seal packing (JPK-16, GP-13.5,
or GPM20), and tighten with the applicable torque. Seal packing is
sold separately.
Maintenance and Repairs
The user must not perform repairs or maintenance. Contact the
machine manufacturer if repairs or maintenance are required.
Storage
Do not store the Switch in locations where harmful gases (e.g., H2S,
SO2, NH3, HNO3, or Cl2) or dust are present, or in locations subject to
high humidity levels.
Miscellaneous
•In conditions requiring greater rigidity, sealing performance, and oil
resistance, use OMRON’s D4BL.
•Perform regular inspections.
