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 roughening of the contact surface and contact reliability may be lost.
*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 D4N-[]R in places where foreign material such as dust, dirt,
       oil, water, or chemicals may penetrate 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. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is
       possible with the actual load beforehand.
