Note 1. When determining the operation key insertion radius, adjust the adjusting screw so that the tip of the operation
             key is positioned to the center of the key insertion hole of the Switch.
         2. The operation key cannot be inserted or adjusted in a direction different from the one shown above.
              Use the D4GS-NK1 or D4GS-NK2 if necessary.

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.
