Note: 1.
The above values are initial values.
2.
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 shown above is based on the test method specified in EN60947-5-1. Be sure to confirm in advance the sealing
performance under the actual operating environment and conditions.
Although the switch box is protected from dust, oil, or water penetration, do not use the D4GS-N in places where dust, oil, water, or chemicals
may enter through the key hole on the head, otherwise Switch damage or malfunctioning may occur.
*2.
The durability conditions are an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. For more details, consult your
OMRON representative.
*3.
When the ambient temperature is 35°C or higher, do not apply 1 A at 125 VAC to more than one circuit.
*4.
These figures are minimum requirements for safe operation.
*5.
The value given for minimum applicable load is a reference value for microloads. The value will vary depending on factors such as the switching
frequency, the ambient environment, and the reliability level. Be sure to confirm correct operation with the actual load before application.
