Helps Ensure Safety during Maintenance
Enabling grip switches are safety components used to prevent unexpected
machine operation when workers perform maintenance or other non-routine
tasks inside hazardous areas, such as areas inside protective shields.
For more information, refer to the Safety Components Series Catalog (Cat. No. Y106).
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.

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.

Safety Precautions
• Do not contact the enabling switch section to the mounting bracket
in Fig.2. Doing so may resoult in malfunction.
!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.
• 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 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 Switch while the Holding Key is being
inserted in the door switch.
• 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.

Precautions for Correct Use
• Do not hold the Enabling Switch Device at Position 2 by any other
methods except for handling. Otherwise, the original function of the
Enabling Switch Device is not worked.
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., H2S, SO2, NH3,
HNO3, or Cl2) 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.

Cover Mounting
• Dislocation of the seal rubber or foreign substance on the seal
rubber reduces seal performance of the switch. Mount the cover
after confirming that there is no abnormality on the seal rubber. If
the seal rubber cracks or breaks, replace the Cover with a new one
(A4EG-OP1 Rubber Cover, separately sold).
• Do not touch the rubber boot with sharp objects. Otherwise, the
rubber boot may break and the operating characteristics and the
seal performance may not be satisfied.

Installing Mounting Bracket
• Securely install the Mounting Bracket using M5 screws and
washers and tighten them to a torque of 2.4 to 2.8 N·m.
• Do not pull the cable when the Enabling
Switch Device is hung on the Bracket.
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.
• 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.
• Use the provide Spring washers and Mounting screws when
mounting the Holding Key. Fit a tip of a slotted-screw driver on the
head of the Mounting screw as shown in the following figure when
tightening Mounting screws. The Mounting screws cannot be
released once tightened.

• As shown in figure 1 in Precautions for Safe Use, install the D4NS
so that its mounting surface is above the highest part of the A4EG.
• As shown in figure 1 in the Precautions for Safe Use, use the
Holding Key inserted vertically to the insert hole.
Using the A4EG-BE2R041 (Enabling Grip Switch
Equipped with an Emergency Stop Button)
If the A4EG is installed in a machine, do not use the A4EG alone as
an emergency stop switch or as an emergency shutoff switch as
specified by SEMI-S2.
SEMI-S2 specifies the installation of emergency shutoff switches at
specified intervals on equipment. The A4EG can be removed from the
equipment, and so may not satisfy the requirements of SEMI. Use the
A4EG in combination with emergency stop switches or emergency
shutoff switches that are installed at fixed positions.
Wiring
• Confirm that safety is satisfied on the operation of the equipment
to wire.
• Do not put the electric power when wiring. Otherwise electric shock
may occur.
• Use an adequate diameter of cable. The seal performance is
reduced when the diameter is smaller than the adequate diameter.
• Use the conforming sizes of lead wires to the apply voltage and
current.
Conforming cable size
Recommended multi-wire cable size: AWG20 to 18
(0.5 to 0.75 mm2)
Recommended cable diameter:
8.0 to 13 mm
(used with provided Conduit
Connector)
• Do not pull the lead wires with excessive force. Doing so may
disconnect them.

• Both of the switches is ON when pushing the two push buttons
simultaneously. Confirm that safety is satisfied on the operation of
the equipment to wire. (A4EG-BM2B041)
• Perform maintenance inspections periodically.
