Enabling Grip Switch with Distinct Feel
for Three Easily Discernible Positions
• In addition to the standard models, the lineup also includes
models with an emergency stop switch and models with a
momentary operation switch.
• An optional Holding Key (sold separately) provides a versatile
method for selecting modes.
• Equipped with conduit connector.
Be sure to read the “Safety Precautions” on page 10.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Features
Positive Operating Feel
Original Double Snap Action switch mechanism lets the operator
precisely confirm the enable position.
Safety Circuits Are Easy to Configure
Safety circuits can be easily configured by combining the A4EG with
the G9SX-GS Safety Guard Switching Unit.

Press the top part... Press the bottom part...
Single-press design ensures a
positive click feel when only one
part of the switch is pressed, to
enable positive confirmation.
The Selector Switch can be used to switch between
normal operating mode (using the Door Switch) and
maintenance mode (using the Enabling Grip Switch).
Selection Based on Application
In addition to the standard models, the lineup also includes models
with an emergency stop switch and models with a momentary
operation switch.
Note: Refer to page 8 for information on
connecting to the G9SX-GS.

Note: The above PL is only the evaluation result of the example. The PL must be evaluated in an actual application by the customer after confirming
the usage conditions.
Application Overview
1. When the emergency stop switch S1 is pressed.
• The power supply to the motor M1 and M2 is turned OFF immediately when the emergency stop switch S1 is pressed.
• The power supply to the motor M1 is kept OFF until the reset switch S2 is pressed while the emergency stop switch S1 is released.
• When normal operating mode (M1 = ON, M2 = OFF) is selected on the selector switch S8, the power supply to the motor M2 is kept OFF until
the guard is closed and the reset switch S2 and S7 are pressed while the emergency stop switch S1 is released.
• When maintenance mode (M1 = OFF, M2 = ON) is selected on the selector switch S8, the power supply to the motor M2 is kept OFF until the
enabling switch is gripped to the middle position and the reset switch S2 and S7 are pressed while the emergency stop switch S1 is released.
2. Normal operating mode (the emergency stop switch S1 is released)
• Normal operating mode (M1 = ON, M2 = OFF) is selected on the selector switch S8. The enabling switch S3 is disabled.
• Power is supplied to motor M2 when the guard is closed.
• After opening of the guard is permitted by turning ON of the lock release enable signal, the lock release switch S5 is pressed, then the guard
lock is released and the guard is opened. Opening of the guard is detected by S4 and S6, and the power supply to the motor M2 is turned OFF
immediately (The power supply to the motor M1 is kept ON).
• The power supply to the motor M2 is kept OFF until the guard is closed and the reset switch S7 is pressed.
3. Maintenance mode (the emergency stop switch S1 is released)
• Maintenance mode (M1 = OFF, M2 = ON) is selected on the selector switch S8 after the motor M2 is stopped. S4 and S6 for detecting the
opening and closing of the guard are disabled.
• After opening of the guard is permitted by turning ON of the lock release enable signal, the lock release switch S5 is pressed, then the guard
lock is released and the guard is opened.
• The power supply to the motor M2 is turned ON while the enabling switch is gripped to the middle position.
• If the enabling switch is released or gripped past the middle position, the power supply to the motor M2 is turned OFF immediately.
• The power supply to the motor M2 is kept OFF until the enabling switch is gripped again to the middle position and the reset switch S7 is pressed.

!WARNING
Fig. 2
Enabling switch section
Always verify the operation of the safety functions before
starting the system. Not doing so may result in the safety
functions not performing as expected if the wiring or
settings are incorrect or the switches have failed.
Do not drop the switch. Doing so may damage the switch
and the system may continue to operate, possibly
causing injury or death.

Precautions for Safe Use
• This product is a switch for teaching the machine such as robot in
hazardous area. The machine is allowed to operate only when
operating the switch continuously. Configure the system so that the
machine can be operated only at position 2.
Precautions for Correct Use
• Apply load current not to exceed the rated value.
• 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.
• Do not hold the Enabling Grip Switch Device at Position 2 by any
other methods except for handling. Otherwise, the original function
of the Enabling Grip Switch Device is not worked.
• Do not use the switch in locations where explosive or flammable
gasses may be present.
• Mount the switch securely to prevent it from falling. Otherwise,
injuries may occur.
• The durability of the switch is greatly influenced by the switching
conditions. Always test the switch under actual conditions before
application and use it in a switching circuit for which there are no
problems with performance.
• Always attach the cover after completing wiring and before using
the switch. Electric shock may occur if the switch is used without
the cover attached.
• The user must not maintain or repair equipment incorporating the
switch. Contact the manufacturer of the equipment for any
maintenance or repairs required.
• Do not disassemble or remodel the switch in any case, or the
switch will not operate normally.
• Do not override by inserting the Holding Key itself in the door
switch.
• Configure the circuit so that the machine does not operate when
operating the Enabling Grip Switch while the Holding Key is being
inserted in the door switch.
Operating Environment
• This switch is designed for use indoors. Using the switch outdoors
may damage it.
• The switch contacts can be used with either standard loads or
microloads. Once the contact 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.
• Do not use the switch in the following locations.
• Locations where the interior of the Protective Door may into
direct contact with cutting chips, metal filings, oil chemicals
• Locations subject to detergents, thinners, or other solvents
• Locations subject to sudden temperature changes
• Locations subject to high humidity and condensation
• Locations subject to severe vibration
• Do not use the switch where corrosive gasses (e.g., H2S, SO2,
NH3, HNO3, or Cl2) are present or in locations subject to high
temperature and humidity. Doing so may result in damage to the
switch as a result of contact failure or corrosion.
• Do not store the switch where corrosive gasses (e.g., H
2S, SO2, NH3,
HNO , or Cl ) or dust are present or in high temperature and humidity.

• If the switch is not turned ON and OFF for a long period of time,
contact resistance may be increased or continuity failure may
occur due to contact oxidation.
• Do not impose excessive vibration or shock on the Door Switch
while the Holding Key is inserted. Excessive vibration or shock
may cause the Switch to fail or break.
• Do not incline and pull the switch body or do not impose shock on
the switch body in the directions shown with the arrows in Fig.1.
Otherwise, the switch may be damaged and may not operate
properly.
• Refer to the D4NS Safety-door Switch Datasheet and Instruction
Sheet about the storage, ambient conditions, the details and
handling of the Switch.

Holding Key Type (sold separately)
• Use the A4EG-OP3 Holding Key when using the A4EG combining
with the door switch.
• Use the D4NS Safety-door Switch.
• Use crimp terminals with insulator tube for wiring.

insulated): J.S.T. Mfg Co. FN1.25-3.7 (F Type)/
N1.25-3.7 (Straight Type)
• Loose screws may result in malfunction. Tighten the screws at the
specified torques. Adhesive is recommended to prevent screws
from being loose.
The specified torque: 0.5 to 0.7 N·m (Mounting screw, 2pcs.)
• Do not impose excessive force on the tip of the Holding Key or do
not drop the switch body when the Holding Key is mounted on the
switch body. Otherwise the Holding Key may deform or break. Stop
using in case that deformation or breakage of the Holding Key
occurs.
