Safety Sensors / Components
Characteristics
Note: 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 chem-
icals may penetrate through the key hole on the head, otherwise Switch damage or malfunctioning may occur.
2.
The durability is for an ambient temperature of 5°C to 35°C and an ambient humidity of 40% to 70%.
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 micro-loads. 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.
