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 D4N-@R in places where foreign material such as dust, dirt, oil, water, or chemicals may penetrate through the head. Other-
wise, premature wear, Switch damage or malfunctioning 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. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the ac-
tual load beforehand.
