Note: 1. The above values are initial values.
2. The Switch contacts can be used with either standard loads or microloads. Once the contacts have been used to switch a load, however,
they cannot 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.
*1. The degree of protection shown above is based on the test method specified in EN60947-5-1. Be sure to confirm in advance the sealing
performance under the actual operating environment and conditions.
Although the switch box is protected from dust, oil, or water penetration, do not use the D4GS-N 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 conditions are an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. For more details, consult your
OMRON representative.
*3. When the ambient temperature is 35°C or higher, do not apply 1 A at 125 VAC to more than one circuit.
*4. These figures are minimum requirements for safe operation.
*5. The value given for minimum applicable load is a reference value for microloads. The value will vary depending on factors such as the switching
frequency, the ambient environment, and the reliability level. Be sure to confirm correct operation with the actual load before application.

Safety Precautions
Be sure to read the precautions for All Safety Door Switches in the website at:http://www.ia.omron.com/.
Precautions for Safe Use
Supplementary comments on what to do or avoid doing,
to use the product safely.
• 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.)
• Although the Switch body is protected from the ingress of dust or
water, the head is not protected. Do not allow foreign substance to
enter through the head. Otherwise, accelerated wear or breaking
may result.
• Do not switch circuits for two or more standard loads (125 VAC,
1 A). Doing so may adversely affect insulation performance.
• Do not use the D4GS-N@ Switch or D4GS-NK@ Operation Key
(rubber color: red) in combination with the D4GS-@ Switch or
D4GS-K@ Operation Key (rubber color: black).
Stopper Installation
Do not use a Switch as a stopper.
Be sure to install a stopper as shown in the following illustration when
mounting the Switch and adjust the stopper so that the Operation Key
is within the setting zone.
Do not subject the Switch to a shock that exceeds the Switch's shock
resistance of 1,000 m/s2.
Stopper
Handling Cables
• Cables must not be bent repeatedly.
• A cable is fixed with sealing materials on the bottom of the
D4GS-N. When excessive force may be imposed on the cable, fix
the cable with a fixing unit at the distance of 5 cm from the bottom
of the D4GS-N as shown.
• When bending the cable, secure the cable with more than 45 mm
bending radius so as not to cause damage to the insulator or
sheath of the cable. Otherwise, fire or electrical shock may result.

Fixing unit
• Do not fasten or loosen the conduit at the bottom of the D4GS-N.
• When wiring, be sure not to allow a liquid such as water or oil into
the tip of cable.

Precautions for Correct Use
Supplementary comments on what to do or avoid doing,
to prevent failure to operate, malfunction or undesirable
effect on product performance.
The Switch contacts can be used with either standard loads or
microloads. Once the contacts have been used to switch a load,
however, they cannot 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.
Wiring
Identifying Wires
Identify wires according to the color (with or without white lines) of the
insulation on the wire.

Appropriate Tightening Torque

• Use the specified sizes of mounting screws flat or spring washers
to mount the Switch and Operation Key, and tighten the screws to
the proper tightening 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.
Mounting Hole Dimensions for Switches
Terminal Numbers
• Identify terminal numbers based on the color of the insulation on
the wire.
• The safety and auxiliary contacts of D4GS-N models of
three-terminal contact construction and those of two-terminal
contact construction are described below. The following shows
contact form with key inserted.
• The auxiliary contacts (orange) can be used as safety contacts.
• The safety contacts are direct opening contacts certified by EN and
each of them is indicated with the mark

• Cut the black dummy insulator and all unused wires at the end of
the external insulation sheath when wiring the cable.
• Depending on the conditions in which the Switch is used, the
rubber of the Operation Key may deteriorate. If the rubber
becomes deformed or cracked, replace it as soon as possible.
