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 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.
*5.The mechanical durability of fork lever lock models is 10,000,000 operations min.

Caution: In the interenst of product improvement, specifications are subject to change without notice.
