Note: 1. The above values are initial values.
2. 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 D4NH in places where foreign material such as dust, dirt,
oil, water, or chemicals may enter through the head. Otherwise, accelerated wear, 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. Be sure to provide this amount to ensure safety in 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.
