Safety Sensors / Components
Characteristics
Note: 1.
The above values are initial values.
2.
Once a contact has been used to switch a standard load, it cannot be used for a load of a smaller capacity. Doing so may result in rough-
ening of the contact surface and contact reliability may be lost.
3.
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 D4NS in places where foreign material may penetrate through the key hole on the head, otherwise Switch damage or mal-
functioning may occur.
4.
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
OMRON representative.
5.
If the ambient temperature is greater than 35
°
C, do not pass the 3-A, 250-VAC load through more than 2 circuits.
6.
These figures are minimum requirements for safe operation.
7.
This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the ac-
tual load beforehand.
Degree of protection (See note 3.)
IP67 (EN60947-5-1)
(This applies for the Switch only. The degree of protection for the key hole is IP00.)
