The Switch contacts can be used with either standard loads
or microloads. 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 D4NS in places where foreign
material may enter through the key hole on the head, otherwise
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.
These figures are minimum requirements for safe 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.
