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 is tested using the method specified by
the standard (EN60947-5-1). Confirm that sealing properties are
sufficient for the operating conditions and environment
beforehand. Although the switch box is protected from dust or
water penetration, do not use the D4NS in places where foreign
material 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%. For more details, consult your
OMRON representative.
*3. Do not pass the 3 A, 250 VAC load through more than 2 circuits.
*4. These figures are minimum requirements for safe operation.
*5. This value will vary with the switching frequency, environment,
and reliability level. Confirm that correct operation is possible with
the actual load beforehand.

Use
!CAUTION
Electric shock may occasionally occur.
Do not use metal connectors or metal conduits.
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.
• Do not switch circuits for two or more standard loads (250 VAC,
3 A). Doing so may adversely affect insulation performance.
Mounting Method
Appropriate Tightening Torque
• Loose screws may result in malfunction. Tighten the screws to the
specified torques.
